Control wiring for features and options should be connected at the customer interface terminal blocks located
inside the IBC–SW.
WARNING
Do not directly connect relay contacts to the mains related circuits. Reinforced insulation to the mains is
required.
Read and understand the following notes while planning and performing the installation:
•
Use Class 1 wiring methods (as defined by the NEC) for interface wiring from 30V to 600V. The wire
should be rated for 600V, 1A minimum. 12 AWG maximum wire size.
•
Use Class 2 wiring methods (as defined by the NEC) for interface wiring up to 30V. The wire should be
rated for 24V, 1A minimum.
•
Because of the battery shunt trip wiring route in the 93PM UPS cabinet, the wiring from the IBC to the
UPS must use wire rated for 600V and Class 1 wiring methods.
•
The battery detect signal wiring from the battery cabinet must be connected to a programmed UPS
building alarm.
•
Battery detect and 48 Vdc shunt trip wiring should be a minimum of 18 AWG.
•
Use twisted-pair wires for each input and return or common.
•
All interface wiring and conduit is to be supplied by the customer.
•
Interface wiring can be installed using the inter-cabinet wiring access pass-through or by routing wiring
through conduit between cabinets.
