Operating Manual
3 Installation and Set-to-work
3.1 Installation
The iUPS101 is supplied ‘close-coupled’ to an Ex ‘e’ terminal box using potted cable
transits. All equipment is suitably certified, and assembled under the relevant codes
of practice (see section 7). This allows simple connection to suitably rated Ex ‘e’
cable terminals by the user.
For reference, the drilled cable entries on the bottom face of the Ex ‘d’ enclosure can
be up to 1-1/2”NPT type or up to M40. The information on the exact type of entry can
be found on the enclosure rating plate. The Ex ‘d’ box should never be opened apart
from scheduled maintenance / inspection by a qualified person. Please see Safety /
Information notes in section 2.
The iUPS101 is only permitted to be mounted in a vertical orientation.
The system weighs approximately 90Kg, so suitable lifting equipment and safety
provisions must be taken to ensure safe installation.
Correct Vertical Installation:

Operating Manual
3.2 Fitting the Cables
Warning!
3.2.1
Installation to be by skilled electricians and instructed personnel in
accordance with national legislation, including the relevant standards
and, where applicable, in accordance with IEC 79.17 on electrical
apparatus for explosive atmospheres.
Grid-connected emergency systems
The UPS can be used as an emergency system, also known as an uninterruptible
power supply (UPS) – enabling a reliable supply to a site connected to an unreliable
network. In the event of an interruption to the energy supply from the public grid, the
UPS, connected to a battery, substitutes the faulty source and enables a support
supply to the users connected downstream.
These will be supplied as long as the energy stored in the battery allows. The battery
will quickly be recharged at the next reconnection to the public grid.
The AC input to the iUPS101 unit must be powered via an external site circuit
breaker/switch to allow disconnection of the power. This should be located close to
the unit and be suitably marked to identify it as the isolating device for the iUPS101
unit.
The use of the UPS must be carried out by qualified personnel who have been
checked by the responsible local authorities. The applicable local standards and
regulations must be adhered to.
3.2.2
Distributed Minigrid
The implementation of the UPS on top of a distributed minigrid requires special care
in choosing the distribution system. A TT distribution is recommended for the DC grid
as well as for the AC grid.
Warning!
3.2.3
The IT system (Power distribution system which is isolated from earth) is
not recommended for the distribution. This distribution is generally
forbidden by local laws
Earthing system
The UPS is a protection class I unit, which is intended for cabling in a grid type TT,
TN-S or TNCS. The earthing of the neutral conductor *(E) is carried out at a sole
installation point, upstream of the RCD circuit breaker *(D).
*(E) Earth-neutral connection bridge:
The neutral is earthed at a single point of the installation, downstream of the source
and upstream of the protection device(s) at the default current (DDR). When several
sources are available, each source must have an earthed neutral. If the source has to
be retained with an isolated earthling system (IT) the applicable local provisions and
regulations must be applied.
*(D) Differential circuit breaker:
A protection device must be installed downstream of the source according to the local
requirements and in compliance with the applicable regulations and standards.
10
Operating Manual
The UPS can be operated with any earthing system. In all cases it is imperative that
the protective earth be connected in compliance with the applicable standards and
regulations. The installer is responsible for the conformity of the installation with the
applicable local standards.
3.2.4
Mobile installation or installation connected to the grid via plug connector
When the input of the device is connected directly to the grid via a plug, the length of
the cable must not exceed 2 m and the plug must remain accessible.
In the absence of voltage at the input, the neutral and live are interrupted, thereby
guaranteeing complete isolation and protection of the cabling upstream of the UPS.
The earthing system downstream of the UPS is determined by the upstream earthing
system when the grid is present. In the absence of the grid, the earthing system
downstream of the inverter is in isolated mode. The safety of the installation is
guaranteed by the equipotential bonding.
Warning!
The connection (link) between the neutrals *(C) upstream and
downstream of the UPS is not permitted in this configuration.
*(C) Connection of the neutrals:
In a fixed installation where the neutral is connected to the earth at a single
installation point upstream of the UPS, it is permissible to carry out a connection of
the neutrals in order to preserve an unchanged earthing system downstream,
independent of the operating mode of the UPS. This choice shows the advantage of
keeping the differential protection devices downstream of the UPS.
This connection (C) is not permitted if a socket is installed upstream of the UPS.
This connection type guarantees the optimal continuity for supplying the UPS loads.
The first isolation fault will not lead to an interruption in the supply. If the installation
requires the use of a permanent isolation controller this would have to be deactivated
when the TT network is present at the UPS input.
Warning!
3.2.5
All sockets and protection class I devices connected downstream of the
UPS must be properly connected to the earth (earthed socket). The
cabling rules above remain valid, including fixed installations, in all
cases where the UPS input is connected to the grid via a plug connector.
Fixed Installation
The installation may be equivalent to a mobile installation (with interrupted neutral). In
a fixed installation where the neutral is connected to the earth at a single installation
point upstream of the UPS, it is permissible to carry out a connection of the neutrals
in order to preserve an unchanged earthing system downstream, independent of the
operating mode of the UPS. This choice has the advantage of keeping the protection
devices downstream of the UPS. This connection can be carried out by modifying the
configuration using the control panel.
In this case the appearance of the first fault will lead to the installation stopping or the
disconnection of the protection devices upstream and/or downstream of the UPS.
Safety is guaranteed by the equipotential bonding and by any RCD circuit-breakers
placed downstream.
This connection (C) is not permitted if a socket is installed upstream of the UPS.
11
Operating Manual
3.2.6
Installation with automatic PE-neutral switching
In certain applications, it is desirable to keep the neutral upstream and downstream
of the UPS separated (C) while re-establishing the earthing system (TN-S, TT or
TNC-S) in the absence of voltage at the input. This can be programmed by the
configuration via the control panel. This modification must be carried out possessing
technical knowledge, at the responsibility of the installer and in conformity with the
applicable regulations and standards.
3.2.7
Connecting the cables
IMPORTANT!
All cables should be connected to the iUPS101 via the correct
cable gland and fitted by a competent person.
IMPORTANT!
Changes in the design and modifications to the equipment are not
permitted. If any changes are performed on the enclosure the
ATEX certification will become void.
Important
The installer MUST ensure that all cables have adequate
mechanical protection to avoid damage to the wires.
IMPORTANT!
Users must read the Installation and maintenance instructions
supplied for the iSTB Enclosure assembly before terminating any
cables. (Included in Chapter 10 for reference)
Remove the cover from the Ex ‘e’ Terminal box and fit the cables in the correct
positions shown below for your product:

3.2.12 Emergency Shutdown Signal
This signal is disabled by default. You must enter the Ex’d’ enclosure to enable this
functionality. More detail on the configuration and behaviour of this signal can be
found in section 4 of this manual.
Emergency shutdown signal is a ‘hot’ 24-48Vdc signal provided by the user. Please
see fig 3.5 for details. The signal is not polarity dependant, and therefore can be the
wires can be inserted in either of the terminals shown in fig 3.5.
3.2.13 CAN bus connections
These are not required on standalone iUPS101 units. These connections are used
when multiple iUPS101 units are connected in a parallel configuration (as per 3.2.10)
with a common battery bank. This is a communication connection between the UPS’s
and is used to allow synchronisation of the AC outputs for parallel UPS’s. Failure to
provide this connection could lead to the system failing to power on or stoppage of
the UPS.
If you are connecting units in parallel, please ensure you have consulted Extronics to
advise that systems are to be connected in this manor, as correct termination of
CANBUS cabling is required internally to the Ex’d’ enclosures. Providing you are
happy your UPS has been configured for parallel operation, you can connect the
CAN wires between the UPS’s as shown in section 3.2.11
Please note connecting cable should be a 3x twisted pair connected in a 1:1 manor
between each UPS.
3.2.14 Connecting the AC supply sources
The UPS is intended to be supplied by alternative voltage sources such as the public
grid or a generator. Check that the rated voltage of the source corresponds to the
rated voltage of the UPS specified on the rating plate.
The source must be connected to the correct ‘Mains AC IN’ shown in the product
diagrams above with sufficient wire section at least equal to the max AC input current
shown in the table 3.0 below.
The AC input current ratings are higher than the output ratings as the system may be
supplying the load and recharging the batteries at the same time following a
discharge.
Important!
There is no circuit protection on the AC input to the UPS. Users should
provide adequate protection against overload by way of a suitable circuit
protection device such as a RCB / MCB or fuse that is correctly rated for
the system– see the table below.

Operating Manual
4 Description and Functioning
4.1 Circuit Diagram
4.2 Description of the main functions
4.2.1
Overview
The iUPS101 contains two major components which work completely independently
to each other to give a high performance industrial inverter charger with the additional
protection required for charging of batteries in hazardous areas. The first component
is the main UPS inverter charger as depicted in the circuit diagram above, and the
second component the Extronics bespoke design battery charge protection circuitry.
4.2.2
Inverter
The IUPS101 is equipped with a high-performance inverter which supplies a perfect
and very precise sine wave. Any unit designed for the 230 V/50 Hz electrical grid may
connect to it without any problem, up to the rated power out of your IUPS101. The
inverter is protected against overloads and short-circuits.
4.2.3
Battery protection circuit
This bespoke circuitry works completely independently to the UPS, providing a fault
tolerant battery charge protection required as per EN60079-7:2007 for charging of
batteries in a hazardous areas. Its function is to monitor the charging voltage and
current from the inverter / charger to ensure they do not exceed dangerous limits
advised by the battery manufacturer. In the event of battery charge failure the battery
protection circuit will ‘trip’ causing the connection between the UPS and the batteries
to be isolated and prevent any dangerous fault conditions transferring to the
batteries.
19
Operating Manual
4.2.4
Automatic load detection
In order to save battery energy, the IUPS101 inverter stops and automatically goes
into load search when the detected load is lower than the sensitivity set by the
configuration. It automatically goes back into operation when a power consumer
greater than this value demands it.
4.2.5
Transfer relay
The IUPS101 can be connected to an alternative power source such as a generator
or public network. When the voltage at the entry satisfies the voltage and frequency
parameters, the transfer relay will be activated after a delay. This delay may be
adjusted (extended) to allow a fully stable status of the generator before transfer.
When the transfer relay is activated, the voltage present at the input of the iUPS101
is available at the output for the consumers connected. At the same time the battery
charger goes into operation.
Important
When the transfer relay of the iUPS101 is active, the voltage at the output
of the IUPS101 is equivalent to that which is present at the input and
cannot be influenced or improved by the iUPS101. The consumers are
supplied by the source present at the “AC IN” input via the transfer relay.
The maximum current of the transfer relay is 50 A. The sharing of energy between
consumers and the battery charger is adjusted automatically. The transfer relay will
be deactivated when the input voltage no longer satisfies the voltage and frequency
requirements at the input or when the current limit is exceeded. If the exceeding of
this limit is prohibited, the UPS passes immediately into inverter mode. In this case
the loads are supplied exclusively by the battery via the inverter. This switching
always takes place automatically. The presence of increased dynamic loads (such as
pneumatic angle grinders, etc.) may lead to an undesirable opening of the transfer
relay due to the weakness of the source. To this case, a delay in the opening of the
transfer relay can be adjusted. The transfer normally takes place without any
interruption when the generator stops. It would typically be 40 ms in the event of the
immediate loss of input voltage at “AC IN”.
4.2.6
Fast voltage loss detection mode (fast transfer):
When the iUPS101 is connected to the public grid or to a generator supplying stable
and clean AC voltage, a fast voltage loss detection mode can be used. In this mode,
perturbation or lack of voltage of less than 1 millisecond can be detected, switching
the unit in inverter mode immediately.
The sensitivity of this detection is adjustable. This mode guarantees a zero or
maximum of 15 ms transfer time, and should not be used in presence of highly
disturbed utility grid or with a low power generator or a generator supplying a poor
quality voltage.
20
Operating Manual
4.2.7
Battery charger
The battery charger for the iUPS101 is completely automatic and is designed in such
a way as to guarantee an optimum charge for the lead-acid batteries. Once the
transfer relay is activated, the battery charger goes into operation.
The battery charger is designed in such a way as to guarantee charging of the
battery that is as complete as possible. The charging process is at four levels by
default and guarantees optimum charging of the batteries. The charging current
should not be adjusted from the supplied settings.
Important!
In its default configuration the iUPS101 does not use constant current
charging.
Important!
Alternative charge profiles can be set up by Extronics for the charging of
NiCd batteries in accordance with battery manufacturers operating
instructions.
4.2.8
The inverter as source backup (“smart boost” function)
The UPS contains a smart boost function where the batteries can provide additional
power to that of the source to increase the available output power; however this must
remain disabled as this will cause the system to operate outside of its rated output
power, and therefore invalidate the safety parameters of the ATEX certificate.
4.2.9
Battery protection
The battery is protected against deep discharge. When the battery has reached the
low voltage disconnection threshold the inverter will stop. The inverter will restart
automatically when the battery voltage has reached the restarting threshold.
This restarting threshold can be automatically readjusted if set to do so, in order to
better protect the battery against repeated cycling in an "almost empty" state of
charge. The restarting threshold is then incremented up to a maximum value,
whenever the LVD (low voltage disconnection) is reached.
If the inverter is repeatedly encountering a low voltage disconnection in a short
period, it will stop permanently and will only start again via an operator’s restart.
When the inverter has stopped permanently and there is no AC input supply, there
will be a natural discharge of the connected batteries by the iUPS101 and internal
battery safety monitoring circuitry.
In order to prevent situations which may cause the UPS to continually draw power
from the batteries, a deep discharge protection module is included. In the event that
there is no AC input voltage present on the iUPS101 for a period of 24hrs, the deep
discharge protection module will disconnect the batteries from the inverter by
deliberately ‘tripping’ the battery protection circuitry. This will cause the battery
isolation relays to open and the system will shut down; requiring the user to reset the
system to power the UPS back on.
21
Operating Manual
IMPORTANT!
For systems with periods of inactivity, such as a long shutdown
or moving/storing a mobile system where the UPS is not in use
and there is no AC mains supply. Users should remove the
incoming AC and DC supplies to the system when not in use.
WARNING!
If the batteries are to be disconnected in a hazardous area, then
an appropriately certified means of isolation must be provided.
WARNING!
All parts of the enclosure must never be opened while energised,
or when an explosive gas atmosphere is present.
4.2.10
iUPS101 protection
The IUPS101 is protected electronically against overloads, short-circuit, overheating
and reverse current (cabling of a voltage source on AC out).
In the event of overload or short-circuit at the output, the inverter stops for some
seconds and restarts. If the inverter is repeatedly encountering this situation in a
short period, it will stop permanently and will only start again via an operator’s
manual control.
If the battery voltage exceeds the programmed value the inverter stops and starts up
again when the voltage is less than the set level. If the iUPS101 is repeatedly
encountering this situation in a short period, it will stop permanently and will only start
up again via an operator’s control.
Important:
4.2.11
Overheating of the UPS due to operation in increased ambient
temperature or rated loads above those specified for your product may
lead to overheating of certain internal components of the unit. In this
case, the device will automatically limit its power output as long as this
abnormal situation persists.
The IUPS101 is protected from reverse polarity by means of a fuse
installed within the Ex ‘d’ enclosure.
Auxiliary contacts
The iUPS101 has two dry reversing contacts that are potential-free. The status of the
contacts in idle mode (deactivated) is indicated by the annotations, N.C. = normally closed
and N.O. = normally open.
Maximum contact loads: 230 Vac / 24 Vdc: 16 A or: max. 50Vdc/ 3A
These dry contacts are programmed by default for the following functions:
Contact no. 1 (AUX 1): The contact has a function of automatic start of generator (two wires).
The contact will be activated when the battery voltage is below a set value, during a given
time. The contact will be deactivated when the charge cycle as reached floating, or when the
Aux. 1 deactivation voltage is reached.
Contact no. 2 (AUX2): Alarm contact by default. It is deactivated when the inverter is out of
service or is working at reduced performance, either because of manual control or if there is
an operational fault such as overload, under-voltage of the battery, over-temperature, etc.
The functions of the two auxiliary contracts can be modified and programmed variously –
contact Extronics for details
22
Operating Manual
If the operator or installer requires different behaviour for the auxiliary contacts, they are both
freely and individually programmable depending on the battery voltage and the inverter
status and the internal clock. The intelligent programming of the auxiliary contacts allows
many applications to be considered such as:
Automatic start-up of the generator (two or three wires)
Automatic load shedding of the inverter (2 sequences)
Global or individual alarm
Automatic disconnection (load shedding) of the source
4.2.12
Remote Emergency Disconnect
Note: This is a comprehensive signal and leads to the stoppage of the
iUPS101
Important:
This function is disabled by default, and can only activated by the
removal of Jumper links LK2 and LK3 on the battery protection PCB
contained within the Ex’d’ enclosure of the iUPS101. See Fig 4.1 below
for location of the jumper links.
23
Operating Manual
The remote emergency disconnect allows users to deliberately ‘trip’ the battery
protection circuitry, which will disconnect the batteries from the UPS and shuts the
system down. This should only be done in the event of an emergency that requires
the AC supply to the load to be removed. The remote emergency disconnect signal is
a ‘hot’ 24-48Vdc supply provided by the user. If the remote emergency disconnect
function is enabled, failure to provide this signal will prevent the iUPS101 from
powering on. Similarly, removal of the signal will cause full system shut down and
loss of supply to the connected load. Details for the connection of this signal can be
found in section 3 of the manual.

7 Messages and account of events
This screen allows you to view the various events
that have occurred in the installation.
The events that occur in your installation are displayed on the remote control screen.
The events are classified within two categories:
The events that may have serious consequences are displayed up to the moment
where the user confirms that he has taken note of them by pressing on an RCC
remote control key. These events are recorded in the event history and may be
consulted subsequently.
Events not posing a risk are indicated briefly on the display and then disappear.
Some are recorded in the event history.
On the other hand, the messages may have different origins and they are preceded
by an attribute to enable you to understand the importance:
Message: normal event but one that conditions or influences the operation of the
IUPS101.
Error: an event that prevents the correct or normal operation of the IUPS101.
Alarm: an event that may cause a malfunction of the installation if it is not corrected.
Stop: The system had to be stopped as a major event is preventing its operation.
Caution, a stop can be temporary and the system can restart automatically.
In case of work on the installation, switch off the system.
INSTALLER - In the message history, you may clear the list of saved messages. The
clear function is signalled by ‘CLR’, opposite the SET button. You must confirm to

be controlled, see parameters {1438}, {1536} and {1549}.
In no case will the feeding source power be bigger than the IUPS101 power.
7.19 (058) Error: Lost of synchro master
A communication problem between the IUPS101s is detected.
Method: check the cabling in betwen the IUPS101s.
7.20 (059) Stop: Overload inverter HW
See code (015)
7.21 (060) (061) Alarm: Maximum duration security for auxiliary
contact
The maximum duration that you have selected for the relay activation with the
parameter {1514}, {1515} is reached and the activation conditions are still present.
The contact will not be reactivated as long as the conditions are present. Therefore
there is a risk that the auxiliary contact remains locked in this position unless you
reset this alarm.
Method: reset manually this alarm with the corresponding parameter ({1512}AUX1,
{1513}AUX2) by deactivating and then activating it.
Use this function with care and only as a security.
7.22 (062) Alarm: Genset problem, no AC-In after a start by means
of the auxiliary contact
The genset start has been driven by the auxiliary contact but there is no voltage at
the IUPS101 input.
Method: check that the genset runs and that its connection to the IUPS101 has not
been interrupted.
7.23 Stored events
Events are stored in the remote control. Any system not permanently connected to a
remote control does not store the events.
39
Operating Manual
To access the event history via one of the basic
displays, change the screen by using the keys UP
and DOWN until the “event history” screen
appears and then validate using the key SET.
The number shown at the top right indicates the
message number. In a system with several
IUPS101s, the events are presented in
chronological order and the lower line indicates
the IUPS101 to which the event refers.
Each event is recorded as well as the date and
time of its occurrence. The keys UP and DOWN
allow you to view all the events that have
occurred.
Where there is a system with multiple IUPS101s,
each message also contains the number of the
IUPS101 that has generated the message.
Quit the message display by using the key ESC
7.24 Utilisation and access levels
The functions described below refer to the EXPERT level. Depending on the user
level selected, access to all the functions may not be possible. Refer to the chapter
on setting the user level of the remote control for more information on this subject.
7.25 Pre-defined functions of the auxiliary relays
The two auxiliary relays (dry contacts) of the inverter-charger IUPS101 are already
programmed with factory settings and can be activated with various functions. They
react to different signals.
The factory settings depend on the IUPS101 models.
For more information on the auxiliary contacts pre-set functions, please see the
inverter-charger IUPS101 manual.
Caution, if your installer or supplier has done pre-settings, these pre-set
functions may have been changed.
7.26 Access to the parameters
You can access to the parameters by two different
ways:
•
•
By its parameter number;
Via the the main menu.
40
Operating Manual
7.26.1 Access to a parameter by its number
Each IUPS101 parameter is directly accessible by its unique reference number. This
function can be used in order to change the value of a parameter or to consult its set
value.
If you know the reference number of a parameter that you want to change, you can
access to it directly with this menu. Move with the keys UP and DOWN to highlight
the parameter then select it by the key SET. You have then the possibility to change
the value of this parameter.
For each parameter, its set value is written opposite to it. If a parameter does not
have a value displayed, this means that you do not have the user level required to
change the value or that the parameter does not have a value (a menu title for
instance).
When you want to access to a parameter which access level is superior to yours, it is
possible to do it only with a code: select the parameter that you want to change with
the keys UP and DOWN then press the key SET. The remote control then displays a
4 digits number. By communicating this number to your installer, you can receive an
activation number which will allow to modify the wanted parameter.
The key received is valid only for one single access to the wanted parameter. This is
why it can be necessary to be online with your installer when it comes to do several
changes.
7.26.2 Access to a parameter via the menu
The IUPS101 configurations are divided into several categories:
•
•
•
•
•
•
•
•
•
•
Basic configurations
Battery and its charge cycle configurations
Inverter configurations
The parameters of charger and input signals
First auxiliary contact configurations
Second auxiliary contact configurations
Auxiliary contact extended function configurations
The parameters of the system
Three-phase or parallel operation configurations
The parameters of grid feeding
According to the user level selected, it is possible to
access several hundred configurations. For this
reason, each configuration has a unique ID
displayed top right. In the event of questions on the
subject of a configuration, ensure that you have this
number at hand.
When you modify a configuration, a star is displayed
to the left of the value if it corresponds to the factoryset value.
The various configurations can be adjusted within a large range. Nevertheless, some
configurations are interdependent and cannot be adjusted beyond the value of other
configurations. You can consult the list of dependencies on the list in appendix 1.

Operating Manual
8 Configuration for auxiliary contacts 1 and 2
{1201} {1310}
The IUPS101 inverter/charger is equipped with two auxiliary relays each with one
free of potential contact (reverser). These two relays allow multiple functions to be
carried out by using adequate cabling as well as simple programming.
The programming of each contact is carried out independently except when
conditions require the use of two relays. In this case, the programmed events for
activating the second relay are automatically deactivated.
The extended functions of the auxiliary contacts are described at the end of the
chapter on simple functions.
The auxiliary contacts are activated immediately in response to the programmed
signals. When the activation conditions are no longer fulfilled, they are deactivated
with a delay of 2 seconds to avoid overswitching.
The auxiliary contacts respond to various signal types presented graphically below.
The following types of basic events may activate the contacts:
• Simple event
• Scheduled event
• Level
In the following description, each parameter has two reference numbers. The
reference on the left relates to auxiliary contact 1 and the reference on the right to
auxiliary contact 2 ({reference of the auxiliary contact 1} {reference of the auxiliary
contact2}).
The auxiliary contacts are factory set with pre-defined functions. If you wish to
implement a specific function you must clear the programming already set.
Use for that purpose the prarmeter {1569} or {1570}.

Operating Manual
8.1.1
8.1.1.1
Simple functions
Switching mode {1202} {1311}
The auxiliary contacts may be controlled in 4 different ways:
Manual ON: In this mode, the contact is permanently drawn whatever the external
conditions or programming
Manual OFF: In this mode, the contact is permanently released whatever the external
conditions or programming
Automatic: In this mode, the auxiliary contact is activated according to the conditions
and restrictions of its programming.
Reversed automatic: In this mode, the conditions and restrictions define the release
of the contact.
8.1.1.2
Combination of events mode {1497} {1498}
This configuration defines how the various events intended to activate the auxiliary
contact are combined.
Either a single event suffices to activate the contact (OR function) or it must have all
the active events in order for the contact to be activated (AND function).
43
Operating Manual
8.1.1.3
Temporal restrictions {1203} {1312}
These configurations allow the time frame to be defined in which the contact should
under no circumstances be activated. Three distinct schedules are accessible in the
form of restriction programs (programs 1 to 3). For each program, it is possible to
select the day of the week where the restriction is activated. If the day is selected it
appears on the screen and if it is not selected it is represented on the screen by two
horizontal lines.
Once the days are selected, it is necessary to adjust the time frame where the
restriction is active using the “starting time” and “finishing time” configurations. If the
finishing time is programmed before the starting time, the restriction time frame is not
taken into account. Below are the configurations with their references:
Program 1 {1204} {1313}

If your installer has made additional adjustments, it is possible that the
restrictions could be active even if they do not appear in one of the three
programs available to you.
8.1.1.4 Contacts activated with set schedules {1269} {1378}
The auxiliary contact can also be activated like a programmable clock. Three different
weekly programs are available.
For each program, the time frame may be applied to one or several days of the week.
If the finishing time is programmed before the starting time, the time frame is not
taken into account.

8.1.1.5.21 Battery charging in periodic absorption phase {1244} {1352}
You can activate the auxiliary contacts on the reduced floating phase and the
periodic absorption phase.
8.1.1.5.22 Autonomy test in progress {1529} {1530}
This parameter allows you to activate the auxiliary relays if an autonomy test is in
progress. In that case, the relays are activated on the two types of test : monthly or
weekly.
8.1.1.6
Contacts activated by the battery voltage {1245} {1353}
These configurations allow activation of the auxiliary contacts if the battery voltage
passes below a selected voltage during a period that is configurable as well. Three
voltages linked to three durations are configurable to activate the auxiliary contact.

If this function is activated, the real battery voltage is compensated according the
power used.
8.1.1.6.2 Deactivate if the battery is in floating mode {1516} {1517}
If you activate one of the auxiliary contacts according to the battery voltage, you can
force the deactivation if the battery is in floating mode. In this way, even if the
deactivation voltage is not reached or if the duration of the voltage deactivation is not
completed, the auxiliary contact will be released.
8.1.1.7
Contacts activated by inverter power or Smart-Boost {1257} {1366}
If the power output of the inverter exceeds a certain level, the contact may be
activated. The excess is linked to a duration. Three power levels linked to three
durations are configurable to activate the auxiliary contact.

Caution :
If the maximum duration for the relay activation that you have selected is
reached and if the activation conditions are still present (for instance a
battery undervoltage), the contact will not be reactivated as long as the
conditions are present. Therefore there is a risk that the auxiliary contact
remains locked in this deactivated state and you will have to reset manually
this alarm by deactivating and then activating this parameter.
Use this function with care and only as a security.
8.1.1.11
Maximum duration of activation {1514} {1515}
When the conditions are met, either one or two relays are activated permanently. If
you wish that the activation duration is limited in time, even if the conditions are met,
you can activate this function. Once the relay is activated, a countdown runs
according to the duration you have selected. Once this countdown is completed the
relay is released, even if the conditions are still there. The relay can not be anymore
activated as long as the activation conditions have not disap-peared.
8.1.1.12 Reset all settings {1569} {1570}
This function serves to reset all previous settings done on the corresponding auxiliary
contact. Once this operation done, the auxiliary contact is not activated anymore.
Caution: this function cannot be cancelled.
Use this function before programming any function for an auxiliary contact.
By doing this way you are sure that you begin with no unexpected setting
who can activate the contact.
8.1.2 AUXILIARY CONTACTS 1 AND 2 EXTENDED FUNCT. {1489}
8.1.2.1
Generator startup
The two contacts may be combined in order to automatically start up a generator
equiped with an electric starter. In this case the two contacts are dedicated to this
function.
Auxiliary contact 1 serves as an operational contact and auxiliary contact 2 as a
startup contact.
49
Operating Manual
The startup condition of the generator
must be programmed with the
configurations of auxiliary contact 1. The
startup is carried out by first activating
the operational contact and then
activating the startup contact. The latter
engages several times, if necessary, to
start up the motor. If a voltage appears at
the terminals of AC In, the startup
contact is released.
A. Main contact hold/interrupt time
{1574}
B. Time before a starter pulse {1494}}
C. Starter pulse (with AUX2) {1492}
D. Number of starting attempts {1493}
8.1.2.1.1
Generator control {1491}
Activates the combination of the two auxiliary contacts for the generator start and the
management of the start impulses.
8.1.2.1.2 Number of starting attempts {1493}
The start contact is activated a limited number of times in order to protect the starter
if the generator has a fault. Once the maximum number of start has been reached,
the operational contact is also deactivated. For a new attempt to be made the
condition that generated the start must disappear and reappear.
8.1.2.1.3 Starter pulse (with AUX2) {1492}
With this configuration you can adjust the time at which the start contact is activated.
8.1.2.1.4 Time before a starter pulse {1494}
This configuration determines the duration between the start attempts. It also
determines the duration between the activation of the operational contact and the first
attempt at restarting.
8.1.2.1.5 Main contact hold/interrupt time {1574}
Some generators must have the main contact completely stopped between the
cranking attempts (choke pulse). This parameter allows to set this duration.
50
Operating Manual
9 Configuration of AC Transfer
9.1 Activate immediate detection of grid outage (UPS) {1435}
This parameter allows to starting the inverter mode as quick as possible in case of
fluctuations of the AC-In grid. This function is useful when it comes to very sensitive
loads that require an uninterruptible power supply (UPS). If this function is active,
being connected to a fluctuating source (weak grid or unstable generator) will lead to
a frequent switching between inverter and charger modes by opening and closing of
the transfer relay.
9.2 Tolerance on the immediate detection of a grid loss {1510}
When the immediate detection of a grid loss is activated, this parameter allows you to
increase or decrease the detection sensitivity. The higher the figure the weaker the
sensitivity.
9.3 Transfer AC-In for delayed transfer opening {1199}
This configuration determines the voltage below which the transfer relay will open
after a certain period of time. The UPS will then run in inverter mode.
9.4 Delay before passing to inverter {1198}
When the input voltage is below the transfer voltage to the inverter, the transfer relay
does not open immediately. With this configuration, the period during which the
transfer remains drawn can be specified. After this duration, the transfer relay is
opened and the inverter function is activated (if the function has not been blocked or
deactivated).
This delay is particularly useful on less stable grids or with generators with an output
voltage that varies considerably during the activation of heavy loads.
9.5 Immediate transfer AC-In voltage {1200}
Use the adjustment of this configuration to adjust the critical voltage for the operation
of equipment that must not experience interruptions. In the case of a fluctuating grid,
if its voltage passes below the value of the configuration this immediately activates
the inverter function, thereby ensuring supply to the consumers.
9.6 Frequency delta accepted above End {1505}
This setting allows you to determine the upper limit of the accepted frequency. This
value is added to parameter {1112}, the output frequency of the inverter. If the
frequency of the source exceeds this value, the transfer relay is opened after the
duration determined by the setting {1507}.
51
Operating Manual
9.7 Frequency delta accepted below End {1506}
This setting allows you to determine the lower limit of the accepted frequency. This
value is subtracted from parameter {1112}, the output frequency of the inverter. If the
frequency of the source is lower than this value, the transfer relay is opened after the
duration determined by this setting {1507}.
9.8 Duration of erroneous frequency before disconnecting the
transfer relay {1507}
If the input frequency is not included among the values determined by the settings
above, the transfer relay is deactivated after the duration determined by this setting.
9.9 AC-In current active filtering {1575}
When this parameter is activated, the current taken on AC-Input is a sinusoid in
phase with voltage. This means only active power is taken from the generator. The
inverter compensates harmonics and reactive current from the source.
This function also avoids fast speed change on the generator due to loads jumps.
For the filtering to work, it is also necessary to activate the Smart-Boost
function {1126} and to authorize the charger {1125}
This function is not possible with Xtender in parallel. Single units, dual or
three phase with only one Xtender per phase are allowed and functional.

10.5 Cleaning and Maintenance Intervals
The cleaning intervals depend on the environment where the system is installed.
10.6 Aggressive substances and environments
The iUPS101 is not designed to come into contact with aggressive substances or
environments, please be aware that additional protection may be required.
10.7 Exposure to external stresses
The iUPS101 is not designed to be subjected to excessive stresses e.g. vibration,
heat, impact. Additional protection is required to protect against these external
stresses.
The iUPS101 will require additional protection if it is installed in a location where it
may be subjected to damage.

Table 7.1
*After running for approximately 20mins at full load above 20ºC, the
max output power available can reduce by up to 15%
The reason this happens is to stop the inverter overheating when running at full load
in high ambient. The output power is reduced slightly to allow the UPS to continue
running and backing up loads. Continued operation at full load may cause the system
to shut down to prevent damage, therefore losing all power to the connected
equipment.
Important!
Users must ensure they do not exceed the ratings shown in Table 7.0. If
the system is operated outside these values, but within those shown on
the rating plate / ATEX certificate, then it is possible the UPS may limit
the amount of power available at the Output to protect against thermal
overheating, or blow a fuse within the Ex ‘d’ enclosure.
Important! Although the iUPS101 rating label states T6, the complete assembly is
only rated at T5 due to the certification of the terminal box
11.3 Replacement Parts
Extronics hold a range of replacement components available for same / next day
dispatch. Should you require any replacement parts, or technical help please contact
Extronics.
The iUPS101 is supplied with spare protection fuses which the user can replace in
the event of a system overload. Please see chapter 3.4 of this manual.
For continuous operation of critical high availability systems, users are advised to
implement a ‘redundant’ iUPS101 - this will ensure vital equipment is permanently
operational in the unlikely event of a failure.
Fitted internally to the Ex ‘d’ enclosure is a coin cell replacement PCB + Coin cell for
the purpose of electronic memory retention (Extronics Drawing / Part No. 331072).
Should this need replacing, please contact Extronics for further information.

11.4 System Run Times
The table below shows system run times with various loads for a 24V system (using
1x iBATT100 Enclosure) and a 48V system (using 2x iBATT100 Enclosures). System
run times are when using new batteries and are based on battery manufacturer’s data at
20ºC discharging to 1.7Vpc

Whilst accurate to the best of our knowledge, Extronics cannot be held
responsible for any discrepancies. System wiring, battery ageing, and
temperature all have an influence on run times. Above 20ºC system run
times will marginally improve, and below this temperature they will
decrease.
