UPS system power wiring preparations
Note: If you are installing a maintenance bypass, provide one of the following:
- a minimum of 2 separate feeds with upstream feeder breakers
- a single feed with 2 upstream feeder breakers: one for the UPS or rectifier
input breaker and one for the maintenance bypass input.
Do not use a single feed or a single feeder breaker to supply
- the maintenance bypass and the UPS, or
- the maintenance bypass and the rectifier input breaker.
If a bypass input breaker is installed in the maintenance bypass and a single-
feed UPS is being installed, a single feed to the maintenance bypass is
acceptable for supplying both the UPS and the bypass.
An additional single feed kit (P-103002165 KIT 93PS-20 SINGLE FEED) is
available for the 93PS 8–20 kW cabinet. Maximum conductor cross section of
the single feed is 35 mm
2
.
WARNING
Do not install units with three-phase input and single-phase output with a
single feed for rectifier (three-phase) input and bypass (single-phase) input.
When you plan and perform the installation, read and understand the following
