2.5 Power Wiring
-
UPS to Battery Cabinet
Use separate conduits for power and signal wiring.
When the battery cabinet is attached to the left side of the UPS, there is a
power cable with a connector on the left side of the UPS. This connector plugs into
a matching connector on the right side of Battery Cabinet running from the circuit
breaker.
If additional battery cabinets are to be used, additional cables and wiring
harnesses of varying lengths are coiled in Battery Cabinet #1. These must be fed
through one or more battery cabinets to connect to matching plugs similarly
numbered.
If battery cabinet is not attached to the UPS, run wiring out through UPS
access panel at the bottom or top of the battery cabinet, following information on
the installation drawings at the end of this section.
