Eaton 93E Generation 2 UPS 100-200 kVA
(380/400/415V)
Cable entries to the UPS are on the lower back wall, and at the bottom of the
cabinet.
External DC input overcurrent protection and disconnect switch for a remote
battery location is to be provided by the user and installed in the immediate
vicinity of the UPS.
Note: 24Vdc Shunt Trip signal wiring from the UPS should be connected to
the auxiliary signal connection of the battery breaker.
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.
Battery back-up time does not exceed one hour. If the battery setting must
exceed one hour, consult the UPS manufacturer.
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 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 cabinets are
used with original accessories. If alternative batteries are used, you must
ensure that the applicable EC directives are met and declare conformity.
To connect the battery cabinet:
1. Turn off the UPS.
2. Check that all the external battery breakers are open.
3. Connect PE-wire (earth) first.
