The UPS cabinet internal batteries are mounted on three shelves at the bottom of the cabinet and connected together as
shown. All connections are accessible from the front of the cabinet after removing the front panel. Each battery string
consists or 24 x 12V batteries connected in series to provide a nominal battery voltage of 288V; and two battery strings,
each containing 24 batteries, can be housed and connected in parallel to increase the battery capacity.
Normally, internal batteries are shipped securely fitted to the cabinet battery trays and fully connected, and no further
action is required when connecting the UPS power cables.
WARNING:
Opening or removing the UPS/Battery enclosure covers will create the risk of exposure to
dangerous voltages if power is connected to the UPS. Battery replacement and connections should only be
carried out by electrically qualified personnel.
If the UPS is delivered without batteries, Uninterruptible Power Supplies Ltd is not responsible for any
damage or malfunction caused to the UPS by the incorrect storage, installation or connection of batteries
by third parties.
Final battery connection must be supervised by the commissioning engineer. Do not attempt to complete
the battery wiring or close any battery isolator before the system has been commissioned.
