UPS System Installation
Eaton 9EHD UPS (80-200 kVA, 380/400/415V) Installation and Operation Manual 4-5
Connect the battery cabinet as follows:
• Turn off the UPS.
• Check all the external battery breakers are open.
• Connect PE first.
• Connect the battery cabinet(s) with cables sized according to cable cross section and protective
devicespecification to ter (positive pole) and - (negative pole).
CAUTION
• 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.
WARNING
ENSURE CORRECT POLARITY!
Refer to instructions provided with the battery cabinet or by vendor.
