Troubleshooting - Siel SAFEPOWER-EVO-HF 60 Manuel D'installation Et D'utilisation

Irregular UPS operation is most likely not an indication of a fault but due to simple problems or distraction.
It is therefore advisable to consult the table below carefully as it summarises information which is useful for solving the most
common problems.
ATTENTION: the table below often cites use of MANUAL BYPASS. Please remember that, before resetting proper
UPS operation, it is necessary to verify that the UPS is not in STAND-BY.
If it is, switch on the UPS by accessing the "SYSTEM ON" menu and wait for the start-up sequence to be completed
before removing manual bypass.
For further information, carefully read the sequence described in paragraph "Manual bypass (SWMB)".
NOTE: For the exact meaning of the codes mentioned in the table, refer to paragraph "ALARM CODES"

damage the UPS and/or the load.
Connect the mains to the terminals as indicated in the
Installation paragraph.
Close the switch.
Verify electrical main voltage presence. If necessary,
switch on via batteries to power the load.
Reset protection. Attention: check that there is no
output overload or short to the UPS.
Connect load to terminals
Close the switch.

ATTENTION: Check that there is no output overload or
short to the UPS.
Problem with the mains. Wait until the input mains
