8. MAINTENANCE, WARRANTY AND SERVICE.
This chapter introduces the maintenance of the UPS, including
the maintenance instructions for the power modules, moni-
toring of the Bypass module and method used to replace the
dust filter.
8.1. PRECAUTIONS.
Only qualified maintenance personnel can maintain the power,
control and bypass units.
1. The power unit must be disassembled from top to bottom to
prevent tilting of the cabinet.
2. To ensure safety prior to power and control unit
maintenance, use a multimeter to measure the voltage
between the operational parts and earth to ensure that it is
not dangerous. For example, make sure that the DC voltage
is less than 36 V DC, and the maximum AC voltage is less
than 30 V AC.
3. Hot swapping is not recommended in the control and bypass
units. These units can only be deactivated when the UPS is
in maintenance Bypass mode or when it is completely shut
down.
4. After removing the power unit from the cabinet, wait
10 minutes before opening the cover.
8.2. POWER MODULE MAINTENANCE INSTRUCTIONS.
Confirm that the UPS is operating in Normal mode and that the
Bypass is operating normally before removing the power unit
to be repaired.
1. Make sure that the remaining power modules will not
overload.
2. Turn off the power unit:
a. Activate the LCD panel
→
Operate menu
→
Activate the ‘OFF’ icon on the power module.
b. Press the ‘OFF’ button on the power unit panel for
3 seconds. The power unit exits the system.
3. Remove the mounting screws on both sides of the front of
the power unit and remove it using two people.
4. Wait 10 minutes before removing the cover for repair.
5. After the repair, reinstall the power unit in the cabinet, it
will join the system automatically.
8.3. MAINTENANCE INSTRUCTIONS.
8.3.1. CONTROL AND BYPASS UNIT MAINTENANCE
INSTRUCTIONS.
Confirm that the UPS is operating in Normal mode and the By-
pass is operating normally.
1.
Transfer the system to Bypass mode using the LCD control
panel (see chapter 6.3.4), the load is now powered by the
maintenance Bypass.
a. For 6-slot cabinets (180 kVA), the control module and
the Bypass module form a single module, remove it
directly after removing the screws that secure it to the
cabinet structure.
b. For 10-slot cabinets (300 and 500 kVA), the control
module and the Bypass module are separated, remove
them directly one after another after removing the
screws that secure them to the cabinet structure.
2. Once maintenance is finished, reinsert the modules and
tighten the fixing screws.
3. Transfer the UPS from maintenance Bypass mode to Normal
mode (see chapter 6.3.5).
8.4. BATTERY MAINTENANCE.
•
Pay attention to all of the safety instructions concerning
batteries indicated in section 1.2.3 of the EK266*08 manual.
•
The service life of the batteries directly depends on the
ambient temperature and other factors such as the number
of charges and discharges, as well as their depth. Their
service life is designed to be between 3 and 5 years if the
ambient temperature to which they are exposed is between
10 and 20 °C. Different types of battery with different
service lives are available upon request.
•
SLC ADAPT series UPSs require minimum upkeep. The
batteries used in the standard models are lead acid, sealed,
valve regulated and maintenance free, or lithium. 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.
8.4.1. 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, resulting in a fire hazard.
•
Inside the device, there are permanent dangerous
voltages even without mains supply present through
its connection to the batteries and especially in UPSs where
the electronics and batteries share a box.
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.
8.5. REPLACE DUST FILTER (OPTIONAL).
There are 3~4 dust filters behind the front door of the UPS (see
Fig. 90). Each filter is held in place by staples on each side. The
procedure to replace the filters is as follows:
1. Open the front door and locate the filters at the back.
2. Remove the support.
3. Remove the old dust filters and replace them with clean
ones.
4. Replace the support.
