Input, Output and External Battery Connection
Figure 4.4.1
AC connections are hardwired to a terminal block as seen in the figure above.
The cable sizes, input breakers/outlets and distribution methods used during
installation are subject to the local and national electrical codes of practice,
therefore are not detailed here.
Permanent wiring must be routed to the terminal strip using appropriate materials as
required by local and national codes.
External battery bank connections are described later in this manual.
Ensure UPS is provided with an adequate ground (earth).
4.5.
Battery Connection
The batteries are to be located remotely from the UPS system. Cables have been
provided with the battery package for connection to the UPS system.
The 1000VA and 1500VA unit both use 36VDC battery systems. A minimal battery
system uses three (3) 12VDC nominal batteries in series to give 36VDC nominal.
Multiples of 36VDC battery systems can be paralleled together to increase runtime but
maintain the 36VDC to the UPS. Please note that larger battery systems may require
an external charging system (option available) to supplement the UPS internal
charging system. This is needed to reduce the recharge time of larger capacity battery
systems.
Attention:
Potentially lethal voltage exists within this unit as long as the battery
supply is connected. Do not disconnect the batteries when the unit is in
back-up mode.
Battery cabinet assembly may be heavy. Use suitable lifting equipment.
