Interface Wiring Preparation
Read and understand the following notes while planning and performing the Interface
wiring installation:
S
Control wiring for Battery Aux contacts should be connected at the customer
interface connectors or terminal located inside the battery cabinet. Use Class 1
wiring methods (as defined by the NEC) for interface wiring up to 30V. The wire
should be a minimum of 18 AWG rated at 24V, 1A minimum.
NOTE
The 9395 system can trip a maximum of six battery cabinets total. This applies to both the 1085
standard and High Rate series batteries. If more than six battery cabinets in total are needed in a separate
UPM battery configuration, DO NOT hook up the shunt trips.
S
The Shunt Trip requires 48 Vdc to activate. Use Class 2 wiring methods (as defined
by the NEC) for interface wiring from 30 to 600V. The wiring should be a minimum
of 18 AWG rated at 48V, 1A minimum.
S
All interface wiring between the UPS and battery cabinet is to be provided by the
customer.
S
When installing external interface wiring (for example, battery breaker shunt trip) to
the battery cabinet interface terminals, conduit must be installed between the
battery cabinets and the UPS cabinet. Install the interface wiring in separate
conduit from the power wiring.
S
The Battery Aux and 48 Vdc Shunt Trip signal wiring from the UPS must be
connected to the DC source disconnect device.
S
Torque screw terminals to 20 lb in.

Auxiliary Contact Ratings:
240 Vac @ 15A
125 Vdc @ 0.3A
250 Vdc @ 0.15A
