8. MAINTENANCE, WARRANTY AND
SERVICE.
8.1. BATTERY MAINTENANCE.
•
Pay attention to all of the safety instructions concerning
batteries indicated in section 1.2.3. of manual EK266*08.
•
The service life of the batteries greatly depends on the am-
bient temperature and other factors such as the number of
charges and discharges, as well as their depth.
The service life is designed to be between 3 and 5 years if
the ambient temperature is between 10 and 20ºC. Different
types of battery with different service lives are available
upon request.
•
The
SLC TWIN PRO2 T UL
UPS series requires only min-
imal maintenance. The battery used in the standard models
is lead acid, sealed, valve regulated and maintenance free.
The only requirement is to charge the batteries regularly to
extend their life expectancy.
While the UPS is connected to the mains supply, whether
or not it is running, it will keep the batteries charged and
also offer protection against overcharge and overdischarge.
8.1.1. Notes for the installation and replacement of the
battery.
•
If it is necessary to replace the connection of any cable,
make sure that original materials are acquired through au-
thorised distributors or service centres in order to prevent
fire hazards such as overheating or sparks due to insuffi-
cient gauge.
•
Do not short-circuit the + and - poles of the batteries,
danger of electrocution or fire.
•
Ensure that there is no voltage before touching the bat-
teries. The battery circuit is not isolated from the input cir-
cuit. There may be dangerous voltages between the battery
terminals and earth.
•
Even if the input circuit breaker is disconnected, the internal
components of the UPS are still connected to the batteries,
meaning that dangerous voltages are present.
Because of this, before carrying out any repair or mainte-
nance work, remove the internal battery fuses and/or dis-
connect the connection connectors between them and the
UPS.
Since the battery circuit is not isolated from the input
voltage, there is a risk of discharge with dangerous volt-
ages between the battery terminals and the earth terminal,
and, in turn, through the earth (any metal part of the cab-
inet, including mounts and fittings).
•
The batteries contain dangerous voltages. Maintenance
and replacement of the batteries should be carried out by
qualified personnel familiar with them. No other person
should handle them.
8.2. UPS TROUBLESHOOTING GUIDE.
If the UPS does not work properly, check the information shown
on the LCD screen of the control panel, according to device
models and power. Try to resolve the issue using the steps
shown in Tab. 16. If the issue persists, contact our Technical
Service and Support
(T.S.S.)
.
If it is necessary to contact our Technical Service and Support
T.S.S.
, provide the following information:
•
UPS model and serial number.
•
Date on which the issue occurred.
•
Full description of the issue, including information provided
by the LCD or LEDs and state of the alarm.
•
Power supply conditions, type of load and level of load ap-
plied to the UPS, ambient temperature, ventilation conditions.
•
Battery information (capacity and number of batteries), if
the device is
(B1)
.
•
Any other information considered relevant.
