Control wiring for features and options should be connected at the customer interface terminal blocks located
inside the UPS.
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. Class 2 circuit wiring
must be segregated from Class 1 wiring. The Class 2 wire should be rated for 150V, 1A minimum.
•
Because of the battery shunt trip wiring route in the UPS cabinet, the wire should be rated for a minimum
of 600V.
•
Use twisted-pair wires for each input and return or common.
•
All interface wiring and conduit is to be supplied by the customer.
•
When installing external interface wiring between a building alarm, relay output, battery breaker trip, or
Minislot and the UPS interface terminals, conduit must be installed between each device and the UPS
cabinet.
•
If using conduit, install the interface wiring in separate conduit from the power wiring.
•
All building alarm inputs require an isolated normally-open contact or switch (rated at 24 Vdc, 20 mA
minimum) connected between the alarm input and common terminal. All control wiring and switch
contacts are customer-supplied.
•
LAN and telephone drops for use with Minislot connectivity cards must be supplied by the customer.
•
The UPS battery detect signal wiring from an UPS building alarm must be connected to the battery
disconnect device.
•
Program the battery detect building alarm to read battery open and for normally open contacts.
•
A supplemental 48 Vdc shunt trip signal for the battery disconnect device is provided, but is not required
for normal operation.
