Maintenance
The uninterruptible power supply is designed and produced to last a long time even in the most
severe service conditions. It should be remembered however that this is electrical power
equipment, which requires periodic controls. Moreover, some components have a limited
lifespan and as such must be periodically checked and replaced should conditions so dictate: in
particular the batteries, the fans and in some cases the electrolytic condensers. It is therefore
recommended to implement a preventive maintenance programme, which should be entrusted
to specialized personnel authorized by the manufacturers.
Our Technical Support Service will be happy to recommend the various personalized options for
preventive maintenance.
Periodic operations (to be carried out by trained personnel and with doors closed)
The following operations (which must be done with the doors closed) should be carried out periodically
(e.g. once a month, or more frequently in particularly difficult environmental conditions):
-
Ensure that the air intake slots (located on the front door and at the back of the
cabinet) and the output grilles located on the top of the cabinet are clean;
-
Ensure that the UP
S is working properly (the message “NORMAL OPERATION” will
appear on the display panel). If an alarm message is displayed, check the meaning in
the manual before contacting the technical support service;
-
Perform a battery test with the display panel.
Maintenance inside the UPS (trained personnel only)
Maintenance inside the UPS may only be carried out by trained personnel. The UPS is
designed to power the load when it is disconnected from the power supply line.
High voltage is present inside the UPS even when the power supply and the battery have
been disconnected
After disconnecting the power supply line and the battery cabinet, the trained personnel must wait around
ten minutes for the capacitors to discharge before working on the inside of the equipment.
