The battery wiring used between the battery and the UPS should not allow a voltage drop of more than 1% of
nominal DC voltage at rated battery current.
External DC input overcurrent protection and disconnect switch is to be provided by the customer.

the maximum ratings for continuous–duty rated circuit breakers satisfying the criteria for both. Recommended
disconnect size is based on a maximum full load discharge time less than 3 hours. For longer discharge times a
larger disconnect may be required.

Control wiring for features and options should be connected at the customer interface terminal blocks located
inside the UPS.
Do not directly connect relay contacts to the mains related circuits. Reinforced insulation to the mains is
required.
ATTENTION!
Ne pas directement brancher les contacts de relais aux circuits du réseau. Une isolation renforcée des réseaux
est nécessaire.
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 at 600V, 1A minimum and 12 AWG maximum.
•
Use Class 2 wiring methods (as defined by the NEC) for interface wiring up to 30V. The wire should be
rated at 24V, 1A minimum. When Class 2 circuit wiring must be mixed with Class 1 wiring, use Class 1
wire and wiring methods.
•
Use shielded twisted-pair wires for each input and return or common.
•
All interface wiring and conduit is to be provided by the customer.
•
When installing external interface wiring (for example, building alarm, relay output, battery breaker trip, and
Minislot) to the UPS interface terminals, conduit must be installed between each device and the UPS
cabinet.
•
Install the interface wiring in separate conduit from the power wiring.
•
When installing internal interface wiring to Minislot terminals, route the wiring from the interface entry
conduit landing panels through the internal opening in the Minislot communication bay.
•
All building alarm inputs or remote features 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
relay and switch contacts are customer-supplied and may need to use Class 1 wiring, see above.
•
The building alarms can be programmed to display the alarm functional name.
