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.
