Fig. 10: Connecting External battery Cabinets
For unpacking the battery cabinets, see “Unpacking” on page 4. See page 7 to page 8 for installation
considerations.
NOTE:
The battery cabinet should be placed close to the UPS while still allowing the UPS adequate
ventilation.
NOTE:
Due to the weight of each battery cabinet, see “Appendix A: Features and Specifications” on
page 30 to ensure the area chosen is capable of supporting the total weight.
Battery cabinets (1 or 2 units) can be connected to the UPS. A cable used for connecting the batteries to
the UPS (or battery cabinet to battery cabinet as shown in Figure 10) is provided with each battery cabinet.
NOTE:
External battery cabinets can be replaced during “normal operation” of the UPS (“hot
swappable”). However, care should be taken not to install or remove battery cabinets during an input AC
power failure or during “On Battery” operation (UPS is in the status “AC Fail = On Battery”)
NOTE:
The unit indicates an alarm condition when the battery is not connected.
To connect an external battery cabinet:
1. Insure that the circuit breaker on the back of the external battery cabinet is in the “OFF” position.
2. Using the supplied keyed cable, plug one end of cable into the back of the battery closest to the UPS.
3. Plug the other end of the keyed cable into the UPS battery sockets.
4. Turn the external battery cabinet’s circuit breaker to the “ON” position.
NOTE:
If your UPS has an integrated battery, a compensating current may occur during connection when
the circuit breaker is put in the “ON” position.
To connect an additional battery cabinet:
1. Insure that the circuit breakers on each battery cabinet are in the “OFF” position.
2. Using the supplied cable, plug one end of the cable into the back of the additional battery cabinet.
3. Plug the other end of the cable into the first battery cabinet, see Figure 10 above.
4. Turn all the external battery cabinet’s circuit breakers to the “ON” position.
WARNING:
The operation of the UPS may only be carried out by qualified technical personnel according
to local and national electric codes such as NEC.
