UPS for 400 Vac Grid, User Guide, doc. rev. 4
If you remove a power module from the UPS while the module is operating, wait five
minutes before reinserting the module. This allows the module’s capacitors time to
discharge.
FAST FUSES (SEMICONDUCTOR FUSES) must be used between the battery and the UPS –
for example, the Ferraz Shawmut A70QS fuse.

WARNING - RISK OF LETHAL ELECTRIC SHOCK:
The battery cabinet contains a series of batteries that provides high

servicing.
