Check the personnel training
The use of the operation and control devices of the UPS is intended for authorized
personnel only. We recommend to check the training of the personnel responsible for
the use and maintenance of the system.
3.5.1 Isolators
The isolators provided on the UPS are used to isolate the power components of the device from
the AC supply line, from the storage battery and from the load.
Voltage present on terminals
The isolators do not isolate the UPS completely, since AC voltage is still present on
the UPS input terminals. Before carrying out any maintenance on the unit:
 Isolate the device completely by operating the external circuit breakers;
 Wait at least 5 minutes in order to allow the capacitors to discharge.
