Low Voltage Disconnect Option
An optional Low Voltage Disconnect (LVD) is available for the Access Power Solutions
(APS3-300 Series). See the diagram on page 3 for location. This is connected as a battery
disconnect.
For information on operation see Low Voltage Disconnect (LVD) in the System Controller
Operation Handbook.
Battery Mid-point Monitoring Option (SC200 only)
Battery Mid-point Monitoring provides a cost-effective method for the early detection of
internal battery faults. The voltages of the two halves of a battery string are measured and the
system controller generates an alarm signal if a voltage imbalance is detected.
A voltage imbalance is an indication that one or more cells has an internal fault. Further
investigation can then isolate the faulty cell(s) and action can be taken to correct the problem
and prevent a total battery failure.
To connect Battery Mid-point Monitoring see details on page 28. If a String Fail alarm is
generated see Troubleshooting on page 48.
To ensure reliable operation Mid-point Monitoring operates only when the battery is in float
charge and after a configurable lockout period since the last battery discharge, Fast Charge,
Equalize or Battery Test.

Access Power Solutions Installation and Operation Guide (APS3-300 Series)
Battery Time Remaining
The SC200 or SC100 obtains characterization data from either periodic battery discharges
(SC100) or every full battery discharge (SC200), to a specified end voltage.
During a battery discharge, the SC200 or SC100 uses this characterization data to calculate an
estimated time until the battery will reach the specified end voltage.

If a battery disconnect LVD is fitted then the end voltage will usually be the voltage at which the
LVD disconnects the battery.

Battery Time Remaining is designed for a constant power load. The accuracy of the time
remaining calculation will be reduced if the dc power system is connected to a predominantly
resistive (constant current) load.

The time remaining calculation will not be correct if a non-essential load is disconnected during
the battery discharge.
For details refer to Battery Time Remaining in the SC200 or SC100 System Controller Operation
Handbook (see Related Information on page i).

Access Power Solutions Installation and Operation Guide (APS3-300 Series)
Warnings
This section contains important warnings. Read these warnings before installing or operating an
Eaton Access Power Solutions dc power system.

Electrical Safety
Access Power Solutions (APS3-300 Series) dc power systems must be mounted in an enclosed cabinet that
meets safety and fire enclosure requirements as specified in AS/NZS 60950.1 and EN 60950-1.
The dc power system may be powered from multiple ac sources. All ac sources must be isolated before
internally servicing the equipment.
The dc power system MCBs are not a disconnect device. The APS dc power system must be connected to
a suitable upstream ac supply disconnect device such as Miniature Circuit Breaker(s) (MCB) or fuses.
This device must isolate both the phase and neutral conductors in single-phase and three-phase
connections, unless the neutral conductor is clearly identified.
If the dc power system is to be installed in a location where the ambient temperature may rise above 50ºC
(122ºF), then 90°C rated cable rated cable must be used for all connections.
The dc power system is not compatible with IT (Impedance Terra) ac power distribution topologies. For
advice see Worldwide Support on page 101.
A registered electrician (or suitably qualified person) must check the integrity of the installed cabling,
BEFORE the dc power system is powered up.
Tasks must be performed in the sequence documented in this guide.

Location and Environment
An APS dc power system must be installed in a restricted access location.
For ease of access and to maintain optimum system cooling observe the clearances stated on page 25.
Dust build-up within the dc power system may cause premature failure. In dusty environments filter the
ventilation air entering the equipment room. Ensure regular cleaning of the air filters.
Do not allow water or any foreign object to enter the dc power system. Do not place objects containing
liquid on top of or near the unit.
Flooded cell and VRLA lead acid batteries can emit explosive gases and must be installed with adequate
ventilation. Refer to the battery manufacturer or supplier for advice on minimum ventilation levels.

Reverse Polarity
Always check that the battery cables have been terminated to the correct system polarity BEFORE
connecting the batteries or closing the battery disconnect device. Connecting batteries to the dc power
system with incorrect system polarity will damage the rectifiers and void all warranty claims.

Hazardous Energy Levels
Rectifiers and batteries contain hazardous energy levels. Only personnel trained and experienced in dc
power systems are to service/maintain this equipment.
Always use insulated tools.
Do not short-circuit the live and common bus bars or cables.

November 2012
Preparation

Batteries
The plastic cases of batteries installed in Eaton dc power system racks must have a flammability rating of
UL 94-V2 or better.
Flooded cell and VRLA lead acid batteries can emit explosive gases and must be installed with adequate
ventilation. Refer to the battery manufacturer or supplier for advice on minimum ventilation levels.
Do not wear a synthetic dust-coat or overalls. Synthetic fabrics can hold static electric charges that create
sparks during discharge.
Remove rings, wristwatch and other metal jewelry that might be exposed to battery terminals, before
installing batteries.
Batteries are powerful sources of energy and present a potential electrical shock and energy hazard. The
energy hazard is always present, even if the batteries are not connected. Avoid short circuiting terminals
of opposite polarity.
Always use insulated tools.
Do not place tools, loose cables or metal objects (such as interconnecting bars) on top of batteries.
Do not drop tools, loose cables or metal objects onto intercell connections or terminals of opposite
polarity.
Only terminate cables and interconnecting bars after confirming that the termination will not create a
short circuit.
Always tighten battery terminal bolts according to the battery manufacturer’s specification. Failing to do
so can cause erratic battery performance, possible damage to the battery, and/or personal injury.
There is a risk of electric shock or explosion if a battery is replaced by an incorrect type.
Dispose of batteries according to the instructions on page 63.

Rectifiers
Only operate the rectifiers when the surrounding area is clean and dust free.
To reduce the risk of electric shock and maintain optimum system cooling, always cover empty rectifier
slots with blanking panels.
To avoid electrical shock, do not place hands inside the rectifier magazine.
Rectifier cases may exceed 100ºC (212ºF), especially after prolonged operation. Use suitable gloves when
removing a rectifier from the magazine.
Do not attempt to disassemble faulty rectifiers. Return them (in their original packaging) with a
completed Equipment Incident Report on page 99.
Ensure that any upstream Residual Current Devices (RCDs) are appropriately rated for the rectifiers'
maximum earth leakage current (see Specifications on page 69 for value).

DC Distribution(s)
The dc common bus of the dc power system can be connected to earth (ground). If this connection is
made all of the following conditions must be met:
Your equipment and the dc power system must be located within the same premises.
No switching or disconnecting devices are allowed in the conductor between the dc common line
and the point of connection to the earth electrode conductor.
See Connecting the Output to Earth on page 19 for further information.
For installations in the United States, Listed compression connectors must be used to terminate Listed
field-wired conductors where required. For all installations, use the appropriate connector for the
conductor size as specified by the connector manufacturer. And use only the connector manufacturer's
recommended tooling or tooling approved for that connector.
Follow all applicable local and national rules and regulations when making field connections.
Tighten all electrical connections to the torques stated in this guide or on the manufacturer's label.

Step 2 - Check high ac voltage protection at the site
1
Check if the ac voltage is expected to exceed 275V (L-N).
2
If so, then it is strongly recommended that an external high voltage protection
unit (HVPU) be installed. This will automatically disconnect the ac at high
voltage and reconnect it at normal voltage.
3
Install the HVPU as in the following diagram.
4
Connect the High VAC alarm output to one of the Digital Inputs on the I/O
board (see the diagram on page 7 for location).

Step 3 - Check the type of ac supply, disconnect device and RCDs
1
Check the type of ac supply. Only the types of ac supply listed in Task 3 on page
22 are suitable for the APS.

Only use a two-phase or three-phase (L-L) ac supply if referenced to earth, or a
protection system is in place so that the phase-earth voltage cannot exceed the
rating of the rectifier.
2
Check that the APS will be connected to a suitable upstream ac disconnect
device such as Miniature Circuit Breaker(s) (MCB) or fuses.
3
Check the disconnect device will isolate both the phase and neutral conductors
in single-phase and three-phase connections, unless the neutral conductor is
clearly identified.
4
Check that any Residual Current Devices (RCD) upstream of the APS are rated
for the maximum earth leakage current of the rectifiers. If necessary, install
higher rated RCD(s).

The maximum earth leakage current of Access Power Rectifiers is given in the
Specifications on page 69.

Step 4 - Check ac discrimination
Each rectifier has two internal fast-acting fuses. Under certain internal fault
conditions these fuses will blow.
If there is insufficient discrimination between these fuses and any upstream ac
supply-disconnect device then the upstream ac supply-disconnect device will
operate before a rectifier fuse blows. This will disconnect the ac supply to all
rectifiers.
1
Check the time-current (tripping) curve(s) of all ac supply-disconnect device(s)
upstream of the APS with the following curve for the rectifier fuses.

Refer to the manufacturer's data for tripping curves.
Time-Current Curve
(minimum and
maximum) for rectifier
internal fuses (IEC
60127-2).
Source: Schurter SP 5x20
Pigtail data sheet.
2
No action is required if the time-current curves of the upstream ac
supply-disconnect devices are entirely to the right of the curves for the rectifier
fuses.
3
If the curve of an upstream ac supply-disconnect device crosses the curve for the
rectifier fuse there may not be adequate discrimination.
If necessary, replace the upstream ac supply-disconnect device to achieve
adequate discrimination. Or, contact your Eaton dc product supplier for advice
(see Worldwide Support on page 101).

Notes:
1
Torque settings are for mild steel, brass and stainless steel.
2
Torque is based on 60% of yield stress of the material. Yield for the purposes of this chart is
240MPa.
3
Tolerance range is 60 - 70 % of yield.
4
When a bolt and nut is torqued use a spanner to prevent rotation.
5
Use hand tools when loosening and tightening stainless steel fasteners. Lubricate bolts
before tightening to prevent them locking up.

Transi ent Protecti on
e
n

F
To prevent damage to Eaton Access Power Solutions from lightning and transient
over-voltages, structural lightning protection and transient protection must be installed at each
site.
Transient protection will also protect against other sources of transients, such as:
Circuit or grid switching by the power company
Electrical switching of large inductive loads (such as motors, transformers, and electrical
drives) or capacitive loads (such as power factor correction) or manufacturing equipment.
Use a suitably qualified consultant to develop a transient protection plan (compliant with IEC
61643-12) for the equipment to be installed at the site. The transient protection plan and
associated installation must:
1
Capture the lightning strike at a known and preferred point outside the building
2
Conduct the main lightning energy safely to earth
3
Dissipate the lightning energy into a low impedance earthing system
4
Eliminate earth potential differences inside the building
5
Protect the ac supply using a coordinated transient voltage surge suppression plan, that
includes:
Primary surge protection
Secondary surge protection
Primary / secondary surge decoupling coils
Secondary / tertiary surge decoupling coils
6
Protect the data and control lines using a coordinated transient voltage surge suppression
plan
Earthing (Grounding)
The most important aspect of any power system installation at a site is the integrity of the
earthing systems. Effective earthing will significantly increase site protection. Most sites have a
number of earthing systems such as:
AC Power earth
DC Power earth
Tower / building lightning protection earth
For optimum protection, all earths must be brought together at one "star" point. Otherwise,
surge currents can flow within the system creating large voltages. These can cause damage to
equipment that does not normally require surge protection, such as rectifier outputs and
communications interfaces.
If there is a tower on the site then use the tower earth as the "star" point. This is because it
conducts the majority of the surge to earth, especially if the site is lightning-prone. For other
sites, a 'direct-lightning' earth will not be available therefore a structural or power system earth
will be used. In multi-floor buildings, always try to use structural earths if the common earth
point cannot be found at ground level. For basements / single floor buildings, the ac supply
earth is usually the most appropriate.

Access Power Solutions Installation and Operation Guide (APS3-300 Series)
Primary Transient Protection
Primary transient protection must be considered at all sites. Eaton recommends primary
transient protection on the incoming ac supply either at the main ac switchboard or
sub-switchboard.
In the absence of sufficient information, primary transient protective devices with a minimum
repeat strike rating of 100kA (8/20μs wave shape) are recommended.
In addition, primary transient protection must be coordinated with downstream secondary
transient protection via suitably rated surge decoupling coils. These should have been specified
as part of the transient protection plan for the site. If no surge decoupling coils were specified,
then air-core 15 H surge decoupling coils are suitable.
Installation
Install the transient protection according to the following diagram.

Transient Protection
Transient protective devices are fitted with alarm contacts and visual indicators.
Monitor the status of all externally installed transient protective devices. Either:
Regularly inspect the visual indicators
Connect the alarm contacts to the MOV Fail termination on the I/O board (preferred
option) or to the building management system. See the Connections diagram on page 8 for
location of MOV Fail termination (YH3) and connector pin-outs on page 78.

The alarm signal lines of the external transient protective devices must be isolated from the ac
supply (by voltage-free relay contacts) before connecting these signal lines to the APS dc power
system.
Secondary Transient Protection
Secondary transient protection (downstream from the primary transient protection) must be
present at all sites to protect the dc power system from transients.
Some models of Access Power Solutions are factory-fitted with secondary transient protection
to protect the power system from a limited number of repeated 15kA transients (8/20µs wave
shape).
Factory-fitted secondary transient protection typically consist of:
Phase-to-neutral metal oxide varistors (MOVs) with a voltage rating of 440V, capable of
withstanding temporary over-voltages
A neutral-to-earth spark gap (gas discharge tube)
Surge decoupling coils
If secondary transient protection is not fitted inside the Access Power Solutions, then external
secondary transient protection must be installed in the ac switchboard that supplies the dc
power system.
Carefully consider the residual voltage seen by the dc power system (maximum 6kV) and the
decoupling between the transient protection system and the dc power system. Transients must
be limited to less than 2kA.
Tertiary Transient Protection
Eaton rectifiers are fitted with 6kV/3kA transient protection. This is designed to protect the
rectifiers from voltage spikes generated during operation of the upstream transient protection
system. Do not install rectifiers without adequate upstream surge protection.

The earthing arrangement of your communications equipment determines how the dc common
bus of the dc power system is referenced to earth.
There are two options: ac and dc earths bonded, or ac and dc earths separated.
AC-DC Earth Linked (recommended)
During a lightning surge, very large voltages can develop between ac earth and dc common bus
as the surge current flows through the earth cables to earth.
Access Power Solutions dc power systems are factory fitted with an ac-dc earth link (see the
diagram on page 21). This link prevents these very large voltages from developing and protects
the rectifiers from surge related damage.
If your installation uses a mesh earth, then Eaton recommends that this factory fitted ac-dc earth
link is retained. No further action is required.
However, if your policy is not to bond the ac/communications earth and dc earth (no mesh
earth), then refer to the following instructions to isolate the ac and dc earths.
AC and DC Earth Isolated
Perform the following steps to isolate the ac and dc earths, and (if required) install a transient
protective device.
Step 1 - Disconnect dc common bar from ac earth
1
Remove the screw securing the
busbar to the side of the
chassis.
2
Remove the long screw
securing the busbar, dc
common bar and plastic
stand-off to the chassis and
remove the busbar and
common bar.
3
Use an M4 x 10, pan head, pozi
screw to re-attach the stand-off
to the chassis.
4
Use an M4 x 10, pan head,
self-tapping screw to re-attach
the dc common bar to the
stand-off. Also use a flat
washer if the head of the screw
is not big enough.

Tighten the screws according to
the Standard Torque Settings on
page 67.

Step 2 - Remove or replace the ac-dc Earth Link
Ignore this Step if the factory fitted ac-dc earth link is used.
There are two options if the ac-dc earth link cannot be retained. Either:
If the site surge protection is designed to limit transient ac earth - dc earth
voltages to less than 1500V at the dc power system, then remove the ac-dc earth
link as in Step 1. No further action is required..

Or, if the site surge protection is not designed to limit transient ac earth - dc
earth voltages to less than 1500V at the dc power system, then replace the ac-dc
earth link with a surge protection device.

The surge protection device bonds the ac and dc earths during transient activity
to prevent damage to the rectifiers. The preferred surge protection device is a
transient earth clamp (TEC).

Notes
1
When the rectifiers are turned off, the battery current will supply all the current to the load.
At this time the battery current will equal the load current.
This test assumes there is a current sensor on the dc Load Bus. If batteries are not installed
on the system, connect the load bank to the battery bus.
If the battery current is determined by a summation, conduct the load current test before
the battery current test.
2
The test should be done at the maximum expected system load current.
This test assumes there is a current sensor on the dc load bus.
