8. MAINTENANCE, WARRANTY AND SERVICE
.
8.1.
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, although the UPS is shut-
down. The direct contact can cause electrocutions and burns. All
the operating, less the battery fuse replacing, must be done by
authorized technical staff.
Some internal parts of the UPS (terminals, EMC filters and
measurement circuits) are still under voltage during the
maintenance bypass operating. To cancel all the voltages, the
circuit breakers of mains and bypass of the panel board that feeds
the UPS and the fuse holders of the battery rack have to be
turned «OFF» / «0».
8.1.1. Battery fuses.
Turning on the battery switch and/or fuse holder «ON» or «I»
position,
and only after
displaying the alarm message «BAT T.
SWITCH OPEN, SWITCH IT ON» in the LCD panel.
The battery fuses can only be replaced by ultrafast fuse
models type aR 660V, of the same size and current used in
the equipment and/or battery module.
8.1.2. Batteries.
The useful lifetime of the batteries depends on the ambient
temperature and other factors like the quantity of charging and
discharging cycles and the deep discharges done.
The average lifetime is between 3 and 7 years if the ambient
temperature is between 10 and 20ºC. To have more information of
its status, activate the battery test.
Risk of fire and/or explosion exists if a wrong quantity or
type of batteries is used. Do not dispose the batteries to the
fire: they can explode. Do not open and mutilate the batteries: the
dumped electrolyte is dangerous for the skin and eyes. It can be
toxic.
8.1.3. Fans.
The useful lifetime of the used fans to cool the power circuits
depends on the use and environment conditions. It is
recommended their preventive replacement by authorised technical
staff.
8.1.4.
Capacitors.
The useful lifetime of the DC bus capacitors and those ones used in
the input and output filtering depends on the use and the
environment conditions. It is recommended their preventive
replacement by authorised technical staff.
8.2.
