2.5.4 Connecting External Battery Cabinet
Up to four external battery cabinets may be connected to the SolaHD S5KC Series UPS to provide longer battery run
times�
The external battery cabinet (EBC) requires the use of one of the optional EBC cable kits for connection to the UPS� The
optional cable kits each contain the power and communication cables required for proper operation and monitoring of
the battery modules� The standard cable kit lengths are 1, 3, and 5 meters (3�2, 9�8 and 16�4 ft�) to accommodate different
site installation requirements�
To connect an external battery cabinet:
1. Verify that the EBC DC circuit breaker is open� The circuit breaker is on the front bottom of the EBC frame behind the
bottom two bezels�
2. Connect one end of the battery cable to the external battery connector on the rear of the UPS frame�
3. Connect the other end to the closest corresponding port on the rear of the EBC frame, as shown in
Figures 42
and 43
�
4. Install and tighten the grounding screw on the battery cable assembly, on both the UPS and EBC ends� This screw also
secures the cable assembly to the frames to prevent accidental disconnection�
5. For new systems that included an EBC, the EBC communication card should already be installed in the UPS frame
(IntelliSlot Port #3, typically)� If it is not already in the UPS frame, obtain the EBC communication card and insert it
into any open IntelliSlot port (preferably Port #3)� Connect the provided EBC communication cable to the UPS and
EBC as shown in
Figures 42 and 43
�
6. Check the EBC DIP switch settings on the top rear of each EBC frame� Verify they are set correctly according to
Table 13
�
7. Close the EBC DC circuit breaker and replace the bezels back onto the EBC�
!
WARNING
Risk of hazardous voltage between UPS frames. Can cause damage to equipment, injury and death.
Failure to open the EBC DC circuit breaker before connecting or disconnecting the battery cable between the UPS
and EBC frames can result in hazardous voltages being present between the frames.
