8 Troubleshooting
Cause
Check if there is any problem on
the power supply to which the AC
input cable is connected.
Disconnect all the connected
devices, separate the input power
supply, turn ON the circuit breaker,
reconnect the input power supply,
and turn ON the power switch of
the UPS again. If the normal "status
display" does not appear even if
doing the above, it is judged as a
failure. If the unit is in the normal
state, check the connected
devices.
Lower the value in [3.Settings] -
[Boot Settings] - [Reboot
Batt.level]. When set to 0%, the
battery charging level is not
included in the boot conditions, and
booting is immediate.
Check the voltage and frequency of
the input power from
[1.Measurements] - [Input/Output
Meter].
See "6 Contact signal".
Connect the UPS to the
commercial power supply, and
charge the batteries for 8 hours or
more. If expansion battery units are
connected, more charging time is
required. (24 hours when 1
expansion unit is connected, 40
hours when 2 are connected, and
56 hours when 3 are connected)
