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. Table 3-13
and Table 3-13 list 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.
3.2.4 UPS System Interface Wiring Preparation
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.
AVERTISSEMENT!
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:
l
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.
l
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.
l
Use shielded twisted-pair wires for each input and return or common.
l
All interface wiring and conduit is to be provided by the customer.
l
When installing external interface wiring (for example, building alarm, relay output, battery breaker trip, and
X-Slot) to the UPS interface terminals, conduit must be installed between each device and the UPS cabinet.
l
Install the interface wiring in separate conduit from the power wiring.
l
When installing internal interface wiring to X-Slot terminals, route the wiring through the internal opening in
the X-Slot communication bay.
l
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.
l
The building alarms can be programmed to display the alarm functional name.
l
LAN drops for use with X-Slot connectivity cards must be provided by the customer and may need to use
Class 1 wiring, see above.
