How to start the UPS system from a fully powered-down condition
Initial conditions:
This procedure assumes the following initial conditions:

• The external UPS system output isolator is open.
Power-up the UPS:
1. Connect the UPS system input supply.

WARNING:
The procedures given below must be performed by a trained operator.
WARNING:
When the UPS system is operating on
BYPASS
, the load supply is unprotected if the bypass
mains supply fails. It is essential that the load user is informed of this possibility before you select these
operating modes.
Key Point:
In order to reduce the possible effects of any high inrush currents that might occur when the load is
initially turned on, we recommend that you power-up the load when the UPS system is operating on bypass, as
described in this procedure.
