Description
The AC input power is not con-
nected or is connected to the
UPS output.
Phase inversion on AC input
power. The UPS does not start.
The battery is incorrectly
connected.
A fault is detected on the bat-
tery.
The load level exceeds the
programmed overload level or
UPS capacity.
The UPS is overloaded. Devices
connected to the UPS are fed
directly by the electrical net-
work 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 automati-
cally because of overload at the
UPS output.
The UPS shut down automati-
cally because of a short-circuit
at the UPS output.
A UPS internal fault has
occurred. There are two pos-
sible situations:
w The load is still supplied, but
directly with AC power via the
bypass,
w The load is no longer sup-
plied.
Switching of the Remote Power
Off (RPO) has led to the shut
down of the UPS.
Corrective Action
Check the UPS is correctly connect-
ed to the AC input power.
w In an earthed-neutral system, to
correct the wiring, call an electrician
to modify the connections.
w For all other types of system, dis-
able the detection function.
Check battery connections (see
Section 5.2, Battery-Module
Replacement).
Replace the battery (see Section 5.2,
Battery-Module Replacement). Call
the after-sales support
Check the power drawn by the con-
nected devices and disconnect any
non-priority devices. Check the pro-
grammed overload level.
Check the power drawn by the con-
nected devices and disconnect any
non-priority devices.
Check the power drawn by the con-
nected devices and disconnect any
non-priority devices. Shut down and
restart the UPS to return to normal
operation.
Check the power drawn by the con-
nected devices and disconnect any
non-priority devices.
Check the installation at the UPS
output (wiring, fault equipment).
Call the after-sales support depart-
ment.
Replace the contact in the normal
position, and press the ON/OFF but-
ton to restart.
