Electrical INSTALLATION Liebert Trinergy™ Cube
Installation Manual - 10H52243IM60 - rev. 7 - 06/2020 Page 105
4.9. Connecting the batteries
The UPS is equipped with a separating device for the DC battery power connection.
Before connecting the batteries, please read the notice and warning label on the UPS or battery
compartment.
Notice
Full safety instructions on the use and maintenance of UPS batteries are provided in the
appropriate battery manufacturers' manuals. The battery safety information contained in this
section consists of key considerations which must be taken into account when designing the
installation and may affect its outcome, depending on local conditions.
Warning
Special care should be taken when working with the batteries associated with the Liebert
Trinergy
TM
Cube. When all the batteries are connected together, the total voltage exceeds 500V.
It is very important to make sure that the batteries are separately installed in a specially designed,
lockable, dedicated battery cabinet or battery room.
Warning
In the event of malfunction, the battery shelves and/or cabinet or battery holders may become live!
Notice
The requirements of EC directives are met when battery compartments with original accessories
are used. If other batteries are used, make sure that the applicable EC directives are met and that
conformance is declared. The UPS must still be parameterized with the service software and
equipped with an all-pole disconnecting device and fuses, as per Table 2 “UPS Nominal Current”
on page 84. When dimensioning the battery cables, note the connection tolerances at terminals
+/-.
Warning
MAKE SURE THE POLARITY IS CORRECT!
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, adequate ventilation and heat dissipation must be allowed for.
Valve-regulated cells are not completely maintenance-free. They must be kept clean, and their
connections must be 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, which may take several
hours.
Cell performance typically improves after a few discharge/recharge cycles.
