Maintenance, warranty and service
7.1
Basic maintenance guide.
Batteries, fans and capacitors must be replaced at the end of their useful lifetime.
Inside the UPS there are dangerous voltages and metallic parts at very high temperatures, even after
the UPS is shut down. Direct contact can cause electrocutions and burns. All operations, except battery
fuse replacement, must be done by authorised technical staff.
Some internal parts of the UPS (terminals, EMC filters and measurement circuits) are still under voltage
during the maintenance bypass operation. To cancel all voltages, the mains and bypass circuit breakers
on the panel supplying the UPS and the external battery cabinet fuse holders have to be turned ”OFF“ /
”0“. The internal batteries must also be isolated from the system.
7.1.1
Battery fuses.
Turning on the battery switch or fuse holder according to power of the equipment (“ON” or “I” position) before
alarm message “BATT. SWITCH OPEN, SWITCH IT ON” is displayed on the LCD panel can blow the battery
fuses or switch.
The battery fuses can only be replaced by ultrafast models type Gould aR 660V (14x51 or 22x58 mm,
depending on the unit model) of the same dimensions and rating.
7.1.2
Batteries.
The useful lifetime of the batteries depends on the ambient temperature and other factors such as the quantity
of charging and discharging cycles and full discharges.
The average lifetime is between 3 and 7 years if the ambient temperature is between 10 and 20ºC. For more
information of its status, activate the battery test.
There is a risk of fire and/or explosion if the wrong quantity or type of batteries is used. Do not dispose
of the batteries in a fire: they can explode. Do not open or mutilate the batteries: the dumped
electrolyte is dangerous for the skin and eyes. It can be toxic.
7.1.3
Fans.
The useful lifetime of the fans used to cool the power circuits depends on the use and surrounding conditions.
Their preventive replacement by authorised technical staff is recommended.
7.1.4
Capacitors.
The useful lifetime of the DC bus capacitors and those used in input and output filtering depends on the use
and the surrounding conditions. Their preventive replacement by authorised technical staff is recommended.
