Eaton 93E UPS (15-80 kVA, 380/400/415V) Installation and Operation Manual
4.9 In
ternal Battery Installation
Before connecting the internal battery, please read the notice and warning label on the battery cabinet.
• 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.
• Battery back-up time do not exceed one hour, if the battery setting shall be exceeded
one hour, consult to the professional personnel.
• Battery is to be installed by qualified personnel only.
• 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 r
equirements of the EC directives are satisfied when battery cabinet are used
with original accessories. If alternative batteries are used, you must ensure that the
applicable EC directives are met and declare conformity.
Connect the battery cabinet as follows:
1.
Turn off the UPS.
2.
Check that the internal battery breaker is open.
3.
Connect PE first.
4.
Specification to terminals + (positive pole) and - (negative pole).
Please refer to battery layout drawing next pag
e for proper connection.
Note incorrect connection can result in battery short circuit and arc flash occurring
ENSURE CORRECT POLARITY!
