4.0 Mounting The Battery Cabinet.
CAUTION
The complete external battery assembly is heavy. The charger chassis, empty battery cabinet, and wiring
weigh approximately 25 pounds and all the batteries together weigh approximately 130 pounds for a
combined assembly hanging weight of approximately 155 pounds.
You can mount the battery cabinet at several different locations.
·You can mount the battery cabinet on a separate backboard located to the right of the common equipment
cabinet location. Locate the...

5.3 Wiring The Batteries
The charger has a pair of negative wires and a pair of positive wires (designated by red sleeving near one end of
the wires). This two-wire arrangement divides the current carrying load between the two wires of each pair. The
cabinet’s assembly package includes two individual black wires that you use to wire the circuit breaker to the
batteries. Again, two wires divide the current carrying load between both wires.
The negative wires from the charger are terminated with smaller...

6.0 Connecting The Battery Assembly To The System
1. Connect the AC power and turn on the power supply switch in both DXPPlusmain and expansion cabinets.
2. Connect a battery back-up cable between the battery assembly and the power supplies in the DXPPlusmain
and expansion cabinets.
3. The battery assembly includes a charger that maintains the batteries at full charge. Once you have installed
the battery assembly, connect its AC power cord tothe same AC outlet surge protector that powers the
DXPPlusmain...

7.0 Verifying The Battery Voltage
Every three months, use an accurate voltmeter to measure the no-load voltage of the external battery assembly.
The measured voltage range should be within 27–34.5 volts when the batteries are at full charge.
If the no-load voltage is lower than 27 volts, measure the charging voltage supplied by the common equipment
cabinet. The measured charging voltage must be 35 volts maximum.
If the charging voltage is low or if the voltage of a freshly-charged battery assembly is no...

8.0 Special Cautionary Battery Information
·Do not dispose of batteries in a fire as the cells may explode. Check with the local codes for possible disposal
instructions.
·Do not open or mutilate the batteries. Released electrolyte is corrosive and may cause damage to the eyes or
skin. It may be toxic if swallowed.
·Exercise care in handling batteries in order not to short the battery with conducting materials such as rings,
bracelets, and keys. The battery may over-heat and cause burns.
·Charge the...
