• For detailed instruction on wiring, refer to the Site Planning Data.
• Refer to national and local electrical codes for acceptable external wiring
practices.
• To allow for future kVA upgrades (software and/or hardware), consider using
conductors sized for full bypass rating of the UPS.
• Material and labor for external wiring requirements are to be provided by
designated personnel.
• For external wiring, use copper cable rated for 70°C at minimum. See the
appropriate information in Table
and Table
. Refer to the UPS type plate
for the input and output voltages of the UPS. Cable sizes are based on using
the specified breakers.
• If cables are run in an ambient temperature greater than 30°C, higher
temperature cable and/or larger size cable may be necessary.
WARNING
Do not disconnect the neutral of a supply without disconnecting the phases at
the same time.
• Neutral wire must be sized according to the load. With non-linear load
equipment, neutral wire with a rating of 1.7 times the phase wire is
recommended.
• A readily accessible disconnect device must be incorporated in all fixed input
wiring.
