The remote battery disconnect is crated separately for shipping. The enclosure is designed
to be wall-mounted on a surface that can support the weight and bolt pattern. You can
install a remote battery disconnect anywhere between the remote DC supply and the UPS,
according to national and local codes. Figure 8-1 shows a typical remote battery disconnect
enclosure.
The breaker switch on the remote battery disconnect should be set to the ON position for
normal UPS operation when DC power is available at the UPS. When service personnel are
performing maintenance on the UPS or battery cabinet, the switch should be set to the
OFF position.
Consider the following information before installing the remote battery disconnect:

Installing a Remote Battery Disconnect
There is no DC disconnect device within the UPS.
The DC input to the UPS is only protected by internal fuses F21 and F22.
The UPS DC disconnect trip signal from TB4, points 1 and 2 (shunt trip) or TB4, points 1
and 3 (UV trip) must be connected to the DC source disconnect device(s).
For battery switch dimensions, see Drawing 164201037−14 on page A−38.
