Operation Handbook.
The maximum output current of APS6-600 models with the LVD option is limited. See System
Output.
Battery Mid-point Monitoring Description
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 26. 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.

IPN 997-00012-10A2 July 2018
Battery Time Remaining
The SC300 obtains characterization data from a special characterisation discharge test.
During a battery discharge, the SC300 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 SC300 System Controller Operation Handbook
(see Related Information on page i).

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 (APS6-600 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 105°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 103.
•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 24.
•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.

IPN 997-00012-10A2 July 2018 13

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 65.

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 100.
•Ensure that any upstream Residual Current Devices (RCDs) are appropriately rated for the rectifiers'
maximum earth leakage current (see Specifications on page 71 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.
