8-18 kVA UPS Connections
The 8-18 kVA Liebert UPStation S™ allows the customer
to connect a three-phase input if desired. The only benefit
to connecting a third phase is to balance a three-phase
feed transformer.
The 8-18 kVA Liebert UPStation S™ has two basic
connections; UPS Input and UPS Output. Below is an
illustration of how the system will look electrically once the
installation is complete.
Connections between the maintenance bypass and the
UPS must be run in separate conduit. Due to the
clearance requirements for service on the UPS, it is
recommended that flexible conduit be used.
