External Battery Cabinet Installation (EBC)
Before connecting the external battery, please read the notice and warning label on the battery cabinet.
WARNING
•
In the event of malfunction, the battery cabinet chassis or battery cabinet frames may become live!.
•
Special care should be taken when working with the battery cabinet associated with the equipment. Ensure
the battery number is suited to the setting of the battery charging voltage before installing the battery. When
the battery cabinet is connected the overall voltage exceeds nominal voltage. It is very important to ensure
that the batteries are installed separately, in a dedicated battery cabinet.
NOTE
•
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 maintenace- 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 the batteries will lose
charge during transportation and storage; before attempting to carry out an autonomy test, ensure that the
batteries are fully charged as this may take several hours. Cell performance typically improves after a few
discharge/recharge cycles.
•
The requirements of the EC directives are satisfied when battery cabinet are used with original accessories.
If alternative batteries are used, you must ensure that the appli-cable EC directives are met and declare
conformity.
The default battery settings of the UPS are for 12 VDC VRLA batteries. If requested to use other battery
types, contact your Eaton representative. For the battery specification, see Chapter 8.4 Battery specification.
Connect the battery cabinet as follows:
1. Turn off the UPS.
2. Check all the external battery breakers are open.
3. Connect PE first.
4. Connect the battery cabinet(s) with cables sized according to cable cross section and protective device
specification to ter (positive pole) and - (negative pole).
5. Refer to instructions provided with the battery cabinet or by vendor.
