Safety Notices
WARNING: Carefully read the following safety notices! Failure to observe the instructions may
endanger your life, your health, the reliability of your device or the security of your data.
• Transport the unit only in suitable packaging (protected against jolts and shocks).
• If the equipment is moved from a cold environment to the operating room, condensation may occur.
Before you switch on the equipment it must be absolutely dry. An acclimatization period of at least
two hours is required.
• The equipment must be installed in accordance with the environmental conditions specified
in “Environmental conditions” on page 5 and in Table 3 on page 8.
• Even with all buttons in “OFF” (see chapter “Control Panel for the Linear Plus Rack-mount” on page
16) the device (UPS) is not isolated from the mains. To isolate completely from the mains, the power
cables must be disconnected.
• In case of interruption of the mains voltage, the integrated battery maintains the power supply to the
user equipment.
• Lay all cables so that nobody can stand on them or trip over them. When connecting the device to the
power supply, follow the instructions in the chapter “Installation” on page 7.
• Make sure that no objects (e.g. pins, necklaces, paper clips, etc.) inside the device.
• In emergencies (e.g. damaged case, controls or power cables, penetration of liquids or foreign matter)
switch off the device and contact the appropriate customer service representative.
• Do not connect equipment that will overload the UPS (e.g. laser printers or vacuum cleaners) or
demand DC-current (e.g. half-wave rectifiers).
• When cleaning the unit, follow the instructions in the chapter “Maintenance” on page 21.
• The sum of the leakage currents (protective conductor current) of the UPS and the connected devices
exceeds 3.5 mA for all ratings of the UPS. Earth connection is essential before connecting supply.
• Data transmission lines should not be connected or disconnected during a thunderstorm.
• Emergency Power Off (EPO) input is located on the rear of the unit (see Fig. 5 on page 11). When this
connection is open, the logic circuit will immediately shut down the UPS output.
• In order that the wiring installation safety comply to the European Harmonized Document
HD384-4-46 S1, an Emergency Switching Device (E.S.D.) shall be fitted downstream of the UPS.
• When mounting the unit into a rack, it has to be hooked on both sides and the front plate of the unit
has to be fixed to the rack by screws. The unit has to be fixed in horizontal position.

Safety
Emergency
WARNING: The supply to the load may be interrupted by opening all the switches.
WARNING: DO NOT USE WATER to extinguish any fires that may occur in the area in which the UPS
is installed.
Leakage Currents
WARNING: Connect the earth ground [protection earth (PE)] safety conductor before any other cables
are connected.
Radio Interference
Linear Plus Rack-mount is a class A product.
The UPS device may cause radio interference. Do not place it near devices which are especially
susceptible to electromagnetical interference (e.g. transmitters/receivers, radar, metal detectors, anti-theft
devices).
Batteries
Battery maintenance must be carried out by authorized personnel.
• The batteries installed in external battery cabinets may contain electrolyte. Under normal conditions
the containers are dry. A damaged battery may leak electrolyte which can be dangerous in contact with
the skin and cause irritation to the eyes. Should this happen wash the affected part with copious
amounts of water and seek immediate medical advice.
• Voltage is always present on the battery contacts.
• Even when discharged a battery has the capacity to supply a high short circuit current, which, in
addition to causing damage to the battery itself and to associated cables, may expose the operator to
the risk of burns.
• The voltage of a single cell of a single battery block is not dangerous. However a number of cells or
battery blocks, connected in series, can produce hazardous voltages.
• The battery is a “hermetic” type battery and must not be kept in storage or disuse for periods
exceeding 6 months at 68°F (20°C) without being recharged (having been charged to 100% at the
beginning of any such period). If this period is exceeded it is essential that the batteries be recharged,
which requires that the UPS be switched on. If these conditions are not respected the performance of
the battery can no longer be guaranteed. We advise recharging the batteries at least once every 4
months.
• Since new batteries often do not provide full capacity after an initial charge it may be necessary to
carry out a number of discharge/recharge cycles before optimum performance is achieved.
• In order to protect the environment batteries must be disposed of in accordance with the regulations
governing disposal of toxic and harmful waste.
Repackaging
To re-pack, proceed as follows:
1. Do not pack the equipment until at least six hours have elapsed since the last recharge.
2. Place the equipment in bags made of a material sufficiently porous to allow it to breathe (e.g. 100μm
polyethylene).
3. Do not remove air from the packaging.

extension is connected to the battery connection the UPS (9), each subsequent extension is connected by
means of the battery extension connection cables (16). The cables are designed to be
non-interchangeable, because the sockets (13) are coded.
Connecting Mains
Connect the mains supply to the input terminals of the UPS (see Fig. 5 on page 11 and Table 6 on page 9).
Connecting parallel UPS configurations: refer to chapter “Paralleling UPS Devices” on page 19.
Connecting Load
Cables
1. Open UPS input breaker.
2. Remove terminal area safety cover.
3. Connect loads to “Output” terminals (see Fig. 5 on page 11 and Table 6 on page 9).
4. Connect mains to the corresponding input terminals (see Fig. 5 on page 11 and Table 6 on page 9).
Preparing single mode / parallel mode:
• If UPS is to be operated as single unit connect a 6 awg (10 mm2) jumper between S1 and S2.
• If UPS is to be operated as parallel unit ensure that no jumper is connected between S1 / S2.
External Battery
Connection
WARNING:
•The batteries installed in external battery cabinet may contain electrolyte. Under normal conditions the
containers are dry. A damaged battery may leak electrolyte which can be dangerous in contact with the
skin and cause irritation to the eyes. Should this happen wash the affected part with copious amounts of
water and seek immediate medical advice.
•Do not open or damage batteries. The released electrolyte is toxic.
•Voltage is always present on the battery contacts.
•Even when discharged a battery has the capacity to supply a high short circuit current, which, in addition
to causing damage to the battery itself and to associated cables, may expose the operator to the risk of
burns. The following precautions should be observed when working on batteries:
• Remove watches, rings or other metal objects.
• Use tools with insulated handles.
•The voltage of a single cell of a single battery block is not dangerous. However a number of cells or
battery blocks, connected in series, can produce hazardous voltages.
•The accumulator is a “hermetic” type battery and must not be kept in storage or disuse for periods
exceeding 6 months at 68°F (20 °C) without being recharged (having been charged to 100% at the
beginning of any such period). If this period is exceeded it is essential that the batteries be recharged,
which requires that the UPS be switched on. If these conditions are not respected the performance of the
battery can no longer be guaranteed. We advise recharging the batteries at least once every 4 months.
•Since new batteries often do not provide full capacity after an initial charge it may be necessary to carry
out a number of discharge/recharge cycles before optimum performance is achieved.
•When replacing batteries, replace with the same type and number of batteries and battery packs.
•In order to protect the environment batteries must be disposed of in accordance with the regulations
governing disposal of toxic and harmful waste.
•Do not dispose of batteries in a fire. The batteries may explode.
Before Connecting the UPS and the external battery cabinet, check to see that the battery breaker is in the
“OFF” position.
The battery connection cable plug is keyed to the receptacles on the UPS and battery cabinet. Insure that
the plug notch is correctly aligned with the receptacle guide when connecting the components together.

6. Ensure that all LEDs on the control panel are extinguished. The UPS is now completely shutdown.
Functional Test
NOTE: Supply to the load is not guaranteed during this test, it should not be carried out if a critical load
is connected to the UPS.
It is possible to carry out a functional test of the UPS to ensure that the load is still supplied in the event
of a mains failure.
Simulate a mains failure by interrupting the mains supply to the UPS. If the UPS is operating correctly
and the batteries are fully charged, an acoustic signal at intervals of 4 seconds will be heard and the “ON”
LED indication “MAINS “indicator (6) at the UPS will be extinguished. Once the interval between the
acoustic signals has decreased to 1 second, the UPS will continue to supply energy for a maximum of 3
more minutes, after which it will be automatically switched off.
The load will be supplied from the batteries during the specified emergency supply period. If this is not
the case, please consult chapter “Troubleshooting” on page 25”.
Restore the UPS mains supply. The UPS is ready for operation. Please note, that the batteries have to be
recharged before the complete emergency supply period is again available.
NOTE: The unit indicates an alarm condition, when the battery is not connected.

Fig. 8: Symbols on the control panel of the UPS Linear Plus Rack-mount
The UPS indicates, by acoustic (buzz) and optical (LED) alarms, that a mains failure has occurred and is
still present. Different procedures, described below, may be followed to interrupt work in case of a
persistent mains failure.
Which of the procedures is applied depends, primarily, on the time required to close the program safely
and - if necessary - for an organized shut down of the operating system.
For example, work on a PC, which is individually supplied by the UPS, may be continued until the battery
nears minimum charge level. The buzzer indicates the mains failure periodically (every 4 seconds) and,
when minimum charge level is neared, once a second. This procedure is not often adopted. Although
battery recharge starts immediately when the mains is re-established, it can take several hours to recharge
the battery fully.

The most reliable method, however, is the use of either MopUPS® Professional UPS software or a
ManageUPS® network adapter. With these tools, the projected remaining battery capacity is indicated
both before and during a mains failures. Furthermore, shutdown procedures can be automated. Depending
on the application program, operating system and computer hardware, it can be ensured that in the event
of a mains failure the application programs are automatically closed, the subscribers logged in at the
server are logged out, data is stored, and the operating systems are shut down. For further information
please refer to our publication about the Chloride connectivity solutions.
Once the mains voltage returns, the UPS will restart in the preset mode. Depending on the installed
software, the computer’s status before the mains failure can be re-established.
In the event of overload or internal failure, the load is transferred to the mains via an automatic bypass,
without interruption. As soon as normal conditions are re-established, the unit switches automatically to
the inverter.
Operating modes Linear Plus Rack-mount
The UPS has three different operating modes when it is switched on.
Normal operation (mains supply present)
Fig. 9: UPS Control Panel: “Normal Operation”
17
Chloride Linear Plus Series Rack-mount UPS User Instruction Manual
Operating the Device
The loads are supplied directly from mains via the inverter. Loads are protected against mains failures and
disturbances.
Battery operation (mains failure)
Fig. 10: UPS Control Panel: “Battery Operation”
In the event of a mains failure, the inverter supplies the loads without interruption; the power is supplied
by the battery.
In this operating mode, an acoustical sound is emitted at intervals of approximately 4 seconds. If the
minimum power level of the battery is reached, the signal is emitted once a second.
Bypass operation (overload > 100%, < 150%),for
Fig. 11: UPS Control Panel: BYPASS Operation
In the event of an overload between 105% and 150% of rated capacity, the device switches to bypass and
the inverter is blocked. Power is supplied by the mains supply.
This is not a normal operating state. If the mains supply fails, the loads will no longer be supplied (no UPS
operation).
NOTE: For sustained overloads > 130% of capacity, the output will be disconnected within one hour to
protect the circuitry from overheating.
Parallel operation
Refer to chapter “Paralleling UPS Devices” on page 19.
Remote Power Off
(RPO)
For reasons of safety it is required that UPS Emergency Power Off be effected by removing the
connections between the RPO terminals located on the rear of the UPS next to the Interface COM 3
connector Fig. 5 on page 11 and connecting a switch, having the characteristics of an emergency button,
closed under normal operating conditions and held open mechanically when operated. Once the
emergency condition causing the switch to open has been resolved, open all UPS switches (Input, Output
and Battery) and carry out Switch-on procedure as described above “UPS Start-Up Procedure” on page
14).

Operating the Device
Emergency Power
Off (ESD hardwired)
This Linear Plus Rack-mount UPS is equipped with separate terminals for connecting hardwired customer
protection ESD relays. See block diagram Fig. 7 on page 14 for connection details.
Paralleling UPS
Devices
A maximum of 3 Linear Plus Rack-mount UPSs can be connected in parallel. The units to be connected
in parallel must be of the same type and rating and the settings of these devices must be identical.
General
The units configured as a parallel system may use only common mains supply.
Designing a Parallel
System
When connecting mains and loads to a parallel UPS Linear Plus Rack-mount system additional
distribution has to be taken into account.
A system of 2 parallel UPS blocks can be connected directly to the distribution if the system load doesn’t
exceed the nominal power of the UPS block (configuration: half load, 2 block parallel system)
If the supported load is greater than 50% of the total paralleled UPS load, it is suggested that an external
maintenance bypass be installed.
Parallel System,
Installation and
Operating
First step
1. Ensure, that the mains supply distribution is switched “OFF”.
2. Ensure that all the mains input breakers are switched to “OFF” on all UPSs. All terminals, breakers
and plugs of UPS can be found the respective rear panels of UPS/batteries. Related figures:
see Fig. 5 on page 11.
Second step
1. Remove jumper from Parallel Terminals (S1, S2) from each UPS terminal block (each UPS).
2. Connect the input terminals of all UPS blocks to the mains distribution. See Figure 12 on page 20.

Third step
1. Remove cover of the parallel port of all parallel devices for linking between the UPS
2. Use the 25 pin standard control cable (supplied with UPS) to connect from one of the parallel ports.
NOTE: Parallel UPS are connected in line, not in a circle, i.e.: 2 cables connect 3 UPS units, 1 cable
connects 2 UPS.
Fourth step
1. Close all the input breakers of all parallel UPSs.
2. Close all battery breakers on all extension battery cabinets to the “ |” position.
3. Close the mains circuit breakers to each of the UPSs.
4. The unit will initiate a self-test for approximately 15 seconds. Wait for the yellow BYPASS LED to
illuminate.
5. Press the button
on the first UPS control panel for a minimum of 1 second.
6. Repeat the UPS start-up procedure (step 5) on the second and on third UPS, if present. At this point
all the bypass indicators are extinguished. All inverter indicators illuminate indicating that all
parallel UPS inverters are running. The load is spread evenly across all the UPSs.
In addition to the “LINE” and “BYPASS” LEDs the “LOAD” LED is now illuminated. After a few
seconds the “INVERTER” LED is illuminated and the “BYPASS” LED is extinguished. The UPS is now
in ON-LINE operation. The load is spread evenly across all the UPSs.
Chloride Linear Plus Series Rack-mount UPS User Instruction Manual

Maintenance
NOTE: In a parallel system, on the unit that has been requested to transfer from bypass to on-line
operation (steps 4 and 5), the battery display will pulse illuminate from right to left and the load display
will pulse illuminate from left to right. This indicates the system is waiting for the other UPS system
synchronize to the first unit. It is critical that after pushing the “ |” button on the first UPS that the second/
third Unit(s) also follows within 1 minute of starting the first UPS. Otherwise, the system that did not
respond within the time allowed will shut down with a parallel fault. See “Troubleshooting” on page 25.
Maintenance
Test, Replacement
and Disposal of
Batteries
The UPS does not require maintenance by the user, however, battery maintenance is recommended in
accordance with IEEE Recommended Practice for Maintenance, Testing and Replacement of
Valve-Regulated Lead-Acid (VRLA) Batteries for Stationary Applications (IEEE Std 1188-1996). When
the batteries expire, trained battery service personnel must replace them. A certified disposal/recycling
company should carry out disposal / recycling of the UPS and / or batteries. Exhausted rechargeable
batteries are classified as “harmful toxic waste” and as such the law demands that they be disposed of /
recycled by an authorized recycling center.
The manufacturer’s service center is fully equipped to deal with such batteries, in accordance with the law
and with the greatest respect for the environment. Contact Technical Support to arrange for maintenance
and/or battery replacement.
The typical battery life cycle is 3 to 5 years, at an ambient temperature of 77°F (25°C), however battery
life is also dependent on the frequency and duration of mains failures or battery discharge cycles.
The battery test should be carried out periodically (6 to 12 months) in order to ascertain the general
condition of the batteries.
Battery
Replacement
WARNING: Prior to starting the battery replacement, please read the entire instructions for important
safety procedures.
NOTE: To obtain new battery(ies), contact Chloride Technical Services at 847-816-6000, toll free at
800-879-5011 option 3.
NOTE: The UPS cannot protect against power outages while the batteries are disconnected.
WARNING:
• External batteries can be replaced during “normal operation” of the UPS by a trained technician.
However, the batteries must not be changed when the UPS is in the status “AC Fail = On
Battery”.The UPS devices Linear Plus Rack-mount 6 and 10 kVA have no internal battery. For
these units the AC power won’t be maintained when an AC Failure occurs during replacement of
the first battery pack!
• Servicing of batteries should be performed or supervised by personnel knowledgeable about
batteries and the required precautions.
• The batteries installed in the UPS and in the external battery cabinets contain electrolyte. Under
normal conditions the containers are dry. A damaged battery may leak electrolyte that can be
dangerous in contact with the skin and cause irritation to the eyes. Should this happen, wash the
affected part with copious amounts of water and seek immediate medical attention.
• When replacing batteries, replace with the same type and number of batteries or battery packs.
• Do not dispose of batteries in a fire. The batteries may explode.
• Do not open or damage the battery cases. Released electrolyte is harmful to the skin and eyes and
may be toxic.
• A battery can present a risk of electrical shock and high short-circuit current. The following
precautions should be observed when working on batteries:
• Remove watches, rings or other metal objects
• Use tools with insulated handles
• Wear rubber gloves and boots
21
Chloride Linear Plus Series Rack-mount UPS User Instruction Manual
Interfaces
• Do not lay tools or metal parts on top of batteries
• Disconnect charging source prior to connecting or disconnecting battery terminals
• Determine if the battery in inadvertently grounded. If inadvertently grounded, remove source from
the ground. Contact with any part of a grounded battery can result in electrical shock. The
likelihood of such shock can be reduced if such grounds are removed during installation and
maintenance (applicable to equipment and remote battery supplies not having a grounded supply
circuit).
Storage
For extended storage at ambient temperature <77°F (< 25°C) the batteries should be charged for 5 hours
once every 4 months, at higher storage temperatures it is advised that this period be reduced to 2 months.
1. Connect the UPS (with attached external battery cabinets) to a mains outlet socket having an earth
connection or install fixed connections (in accordance with chapter “Installation” on page 7) to an
appropriate source.
2. Switch on the input miniature circuit breaker at the rear of the devices (UPS and external battery
cabinet) in the case of fixed connections.
3. After 5 hours, unplug from the mains supply or switch off the input miniature circuit breaker of the
UPS in case of fixed connections, and switch off the circuit breaker of the external battery cabinet.
4. Remove the UPS and external battery cabinet connections in the opposite sequence to that described

Fig. 14: Isolated Contacts Card Interface Signals
INV SHUTDOWN
This input (pin 3) is enabled with a high signal (+5 V to +12 V with respect to pin 4 (0 V)) and when
enabled, switches off the UPS after a mains failure has occurred. After the mains have been reestablished,
the UPS starts again independent of this signal status. This input must be high for one (1) second before
shut off will occur.
AC FAIL
This output provides an N/O (Normally Open) contact between pins 9 and 5, and an N/C (Normally
Closed) contact between pins 8 and 5. The 9-5 contact closes when the mains voltage fails at the UPS
input or when the mains voltage falls below the lower limit for a minimum of 10 seconds. This contact
opens approximately 850 ms after the mains have been reestablished. The 8-5 contact provides a mirror
function, opening when the mains voltage fails and closing when main power returns
LOW BATT
This output provides a N/O contact between pins 6 and 5 and an N/C contact between pins 7 and 5. The
6-5 contact closes when the battery has been depleted to the point that it can only supply current for
approximately three (3) more minutes at nominal load. The 7-5 contact provides a mirror function opening
when the battery is low.
BYPASS ACTIVE
This output provides an N/O contact between pins 1 and 5. The 1-5 contact closes after switching to the
bypass mode. In the bypass mode, energy to the output of the UPS is being supplied by the mains power
and not through the inverter.
SUM ALARM
This output provides an N/O contact between pins 2 and 5. The 2-5 contact closes when one of the alarms
“AC FAIL,” “LOW BATT” or “BYPASS ACTIVE” is active or when the indication “ALARM” at the
front-panel is on.
