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
ambient 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 to which they are exposed
is between 10 and 20ºC. Different types of battery with
different service lives are available upon request.
•
SLC TWIN RT2 series UPSs require minimum upkeep.
The batteries used in the standard models are 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 from overcharging and deep discharge.
8.1.1. Notes for the installation and replacement of the
battery.
•
If it is necessary to replace any connection cables,
original materials can be purchased through our
T.S.S.
or
authorised distributors. Using inappropriate cables can
lead to overheating in connections, which is a fire hazard.
•
Inside the device, there are permanent dangerous
voltages even without mains supply present through
its connection with the batteries and especially in UPSs
where the electronics and batteries share a box.
It is therefore irrelevant if the input circuit breaker of the
distribution board and/or that of the input of the device in
models with power ratings > 3 kVA is turned to ‘Off’.
Also take into consideration that the battery circuit is
not isolated from the input voltage, so there is a risk of
discharge with dangerous voltages between the battery
terminals and the earth terminal, which is in turn connected
to earth (any metal part of the device).
•
Repair and/or maintenance work must be carried out by our
T.S.S.
, except for the replacement of batteries, which can
be performed by qualified personnel familiar with them. No
other person should handle them.
Depending on the configuration of the UPS, certain actions
need to be carried out before handling the batteries:
Devices with batteries and electronics sharing the
same box.
–
Shut down the loads and device completely.
–
Disconnect the SLC TWIN RT2 from the mains.
–
Open the device to access the interior.
–
Remove the fuse or internal battery fuses.
–
Release the battery holders and replace the
batteries.
–
Perform the above steps in reverse to return the
device to how it was at the start, including start-up.
UPS with batteries and electronics in separate boxes.
–
Shut down the loads and device completely.
–
Disconnect the SLC TWIN RT2 from the mains.
–
Disconnect the battery module from the UPS.
–
Open the battery module to access the interior.
–
Remove the fuse or internal battery fuses.
–
Release the battery holders and replace the
batteries.
–
Perform the above steps in reverse to return the
device to how it was at the start, including start-up.
8.2. UPS TROUBLESHOOTING GUIDE.
If the UPS does not work properly, check the information shown
on the LCD screen of the control panel and act accordingly
depending on the device model.
Using the Tab. 23 and Tab. 24 troubleshooting guides, try
to resolve the issue and, if it persists, consult 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 display or LEDs and state of the alarm.
•
Power supply conditions, type of load and level of load
applied to the UPS, ambient temperature, ventilation
conditions.
•
Battery information (capacity and number of batteries),
whether the device is a (B0) or (B1).
•
Any other information considered relevant.
