Description
The AC input power is not con-

UPS output.
Phase inversion on AC input
power. The UPS does not start.
The battery is incorrectly
connected.
A fault is detected on the battery.
The load level exceeds the pro-
grammed overload level or UPS
capacity.
The UPS is overloaded. Devices
connected to the UPS are fed
directly by the electrical network
via the By-pass.
After repetitive overloads, the
UPS is locked in the By-pass
position. Devices connected to
the UPS are fed directly by the
electrical network.
The UPS shut down automatically
because of overload at the UPS
output.
The UPS shut down automatically
because of a short-circuit at the
UPS output.
A UPS internal fault has occurred.
There are two possible situations:
◗ The load is still supplied, but
directly with AC power via the
bypass,
◗ The load is no longer supplied.
Switching of the Remote Power
Off (RPO) has led to the shut
down of the UPS.
