3.9. Connections between battery compartments and UPS
The cables for connecting the UPS to the battery cabinets are not supplied. They can be provided by
the manufacturer upon special request.
A battery area temperature sensor is supplied as standard equipment and includes a connecting cable
with length of 15 meters. Place the sensor in the battery cabinet and monitor it after the UPS
installation.
• The battery cabinet should be installed adjacent to the UPS (see Fig. 2
4
-Fig.
37
for the position of
the input battery connections inside the UPS).
• Make the ground connections (PE).
• Connect the batteries with cables, as suggested in Table 1 on page 3
8
to ter (positive
pole) and - (negative pole), and in accordance with the connection diagram.
• Connect the battery area temperature sensor to connector XP4 in the connectivity panel (Fig.
40
).
• The wires that connect the temperature probe must be shielded and routed in dedicated conduits
that are separate from the power cables.
• If the battery has an external battery disconnector, use customer I/O to monitor the position of the
switch. Appropriate function should be assigned while setting the I/O options.
Notice
The most common battery type used in UPS installations is the valve regulated
battery.
Valve regulated cells are not sealed.
The amount of gas given off is less than for flooded cells, but when planning the
battery installation, allowance must be made for adequate ventilation and heat
dissipation.
Valve-regulated cells are not completely maintenance-free. They must be kept
clean and their connections checked periodically to ensure they are tight and that
there is no evidence of corrosion.
It is inevitable that batteries will lose some charge during transportation and storage.
Before attempting a capacity test, make sure the batteries are fully charged, as this
may take several hours.
Cell performance typically improves after a few discharge/recharge cycles.
Notice
The battery charger can be configured for different types of batteries and different
numbers of cells. In the technical data table (chap. 9. on page 1
02
) lists the type of
batteries that can be used and the number of the cells for which the battery charger is
configured. The maximum charging current is selectable and depends on the rating of
the UPS and its operating conditions (chap. 9. on page 1
02
). Several charging methods
(depending on the type of battery) are available and can be configured by qualified
personnel only.
Warning
Before the system starts, ensure that UPS battery connection polarity is correct. Wrong
connections can damage the system and endanger operator safety
