Receiving and Moving the Unit and the Batteries
Systems weigh several hundred pounds, (see Table 3.4; ask your sales representative for additional
information). Make sure you are prepared for these weights before you unload or move the unit or the
batteries. Do not install any batteries until you have permanently installed the unit and connected all
conduit and wiring.
Storage and Operating Environment
Make sure you store and install the system in a clean, cool, dry place with normal ventilation and level
floors.
Storage Temperature
Store the batteries (in the system) at -18 to 40°C (0 to 104°F). Batteries have a longer shelf life if they
are stored below 25°C (77°F). Keep stored batteries fully charged. Recharge the batteries every 90–
180 days. The system without batteries may be stored at -20 to 70°C (-4 to 158°F).

9 115895B System Installation Manual
Ventilation
The air around the unit must be clean, dust-free, and free of corrosive chemicals or other
contaminants. Do not place the system or batteries in a sealed room or container.
Operating Temperature
System can operate from 20° to 30°C (68° to 86°F) and up to 95% relative humidity. The batteries’
service life is longer if the operating temperature stays below 25°C (77°F).
Batteries
The temperature should be near 25°C (77°F) for optimum battery performance. Batteries are less
efficient at temperatures below 18°C (65°F), and high temperatures reduce battery life. Typically, at
about 35°C (95°F), battery life is half of what it would be at a normal temperature of 25°C (77°F). At
about 45°C (113°F), battery life is one-fourth of normal.
Make sure that heaters, sunlight, air conditioners, or outside air vents are not directed toward the
batteries. These conditions can make the temperature within battery strings vary, which can cause
differences in the batteries’ voltages. Eventually, these conditions affect battery performance.
Do not allow tobacco smoking, sparks, or flames in the system location because hydrogen is
concentrated under the vent cap of each cell of the battery. Hydrogen is highly explosive, and it is
hard to detect because it is colorless, odorless, and lighter than air.
Every type of battery can produce hydrogen gas, even sealed maintenance-free batteries. The gas is
vented through the vent caps and into the air, mainly when the unit is charging the batteries. The
batteries produce the most hydrogen when maximum voltage is present in fully charged batteries; the
batteries do not produce hydrogen during float charging. The amount of current that the charger
supplies to the batteries (not the battery ampere-hour) determines how much hydrogen is produced.
High Altitude Operation
The maximum altitude without derating is 3,048m (10,000 ft). A derating factor of 1% per 305m
(1,000ft) up to a maximum of 4,572m (15,000ft)

INSTALLING BATTERIES AND DC WIRING
WARNING
Only qualified service personnel (such as a licensed electrician) should perform the
battery and DC wiring installation. There is a risk of electrical shock.
This section explains how to install system batteries, fuses, and cables. For all models, you
must install the batteries in the system cabinet. An electrician who is familiar with battery
installations and applicable building and electrical codes should install the batteries.
WARNING
The batteries that will need to be installed in this system could cause you harm or severely
damage the electronics if proper precautions are not followed. Batteries connected in series
parallel configuration could produce lethal voltages with unlimited current. All batteries
should be inspected for damage prior to installation. Never install a battery that is leaking
electrolyte. Battery terminals should be cleaned with a wire brush to remove any oxidation.
All tools should be insulated. Rubber gloves and safety glasses are recommended. IN THIS
SYSTEM BATTERY NEGATIVE IS TIED TO GROUND INSIDE THE INVERTER. This
means that the cabinet and shelves are at ground potential as soon as negative connections
are made to the batteries. It is strongly recommended to make all negative connections to
the batteries the last step to prevent any chance of shorting battery positive to ground. With
the DC fuse(s) removed, make connections to battery positive first, working your way towards
battery negative. Leave individual strings of batteries open at the last battery negative until
all batteries are installed. Then connect each string’s negative.
Safety Instructions
IMPORTANT SAFETY INSTRUCTIONS
SAVE THESE INSTRUCTIONS
This section contains important instructions that a qualified service person should
follow during installation and maintenance of the system and batteries. ONLY a
qualified service person should work with the batteries.
CAUTION
Full voltage and current are always present at the battery terminals. The batteries used
in this system can produce dangerous voltages, extremely high currents, and a risk of
electric shock. They may cause severe injury if the terminals are shorted together or to
ground (earth). You must be extremely careful to avoid electric shock and burns
caused by contacting battery terminals or shorting terminals during battery installation.
Do not touch un-insulated battery terminals.

18 115895B System Installation Manual
A qualified electrician familiar with battery systems and required precautions must
install and service the batteries. Any battery used with this unit shall comply with the
applicable requirements for batteries in the standard for emergency lighting and power
equipment, UL 924 (Canada’s National Building Code). Cabinets are design to be used
with, and batteries must be replaced with, manufacturer battery number BAT-
CG12105X, BAT-CG12150X OR BAT-CG12180X, see the battery wiring diagram that
came with the battery cables. If you substitute batteries not supplied by manufacturer,
the unit’s UL (cUL) listing is void and the equipment may fail. Installation must conform
to national and local codes as well. Keep unauthorized personnel away from batteries.
The electrician must take these precautions:
Wear protective clothing and eyewear. For battery systems >48vdc, wear rubber
gloves and boots. Batteries contain corrosive acids or caustic alkalis and toxic
materials and can rupture or leak if mistreated. Remove rings and metal wristwatches
or other metal objects and jewelry. Don’t carry metal objects in your pockets where the
objects can fall onto the batteries or into the system.
Tools must have insulated handles and must be insulated so that they do not short
battery terminals. Do not allow a tool to short a battery terminal to another battery
terminal or to the cabinet at any time. Do not lay tools or metal parts on top of the
batteries, and do not lay them where they could fall onto the batteries or into the
cabinet.
Install the batteries as shown on the battery-wiring diagram provided with the system.
When connecting cables, never allow a cable to short across a battery’s terminals, the
string of batteries, or to the cabinet.
Align the cables on the battery terminals so that the cable lug does not contact any part
of the cabinet even if the battery is moved. Keep the cable away from any sharp metal
edges.
CAUTION
Install the battery cables so the system doors cannot pinch them.
If you are replacing batteries or repairing battery connections, follow the procedure in
the system user’s Guide to shut down your system and remove both AC and DC input
power.

Before Installing the Batteries
Tools
CAUTION
Always use insulated tools when you work with batteries. Always torque connections to
the manufacturer’s recommendations.
When you work with system batteries, you need the following tools. The tools must
be insulated so they do not short battery terminals to the cabinet. Wear the safety
equipment required by local code whenever the doors are open and whenever you
are working on batteries. Other tools may be necessary for optional batteries.
•Digital volt-ohm meter
•Conductive grease or petroleum jelly
•7/16” socket wrench
•Brush (to apply grease or petroleum jelly to terminals)
•3” extension socket
•Safety equipment required by local codes
•Ratchet
•Torque wrench calibrated in inch-pounds or Newton-meters
•Wire brush
•Safety glasses with side shields
•Electrical tape

Battery Cable Sizing
The battery cable or wire used varies. For the 100 AH battery (BAT-CG12105X) the
size is 6 AWG, for the 150 AH battery (BAT-CG12150X) the size is 4 AWG, and for
the 180 AH battery (BAT-CG12180X), the size is 2 AWG. This is because the
batteries string current varies with battery type.
If the battery cabinets must be more than two feet (0.6 meters) from the main inverter
cabinet, you may need to install larger battery cables between the battery cabinets
and the system. Using long cable runs and larger diameter cables require a modified
installation of the system; call SERVICE if you did not order the longer, larger-
diameter cable with the system.
DC Disconnect
Systems have a Main Battery Circuit Breaker inside the cabinet; this circuit breaker lets you
remove DC power from the batteries.
