Up to 10 optional battery modules (5 connected to each battery connector) can be connected
to the EPS2/EPS5 to provide a dc source when the ac supply is not available.
The battery modules must be connected in series using the supplied plugs and cables.
The battery modules will only operate when the one or both battery circuit breakers are fitted
(see details on page
15) and switched on.
The weight of the battery modules must be fully supported by either fixed side rails or battery
shelves. These are not supplied with the battery modules.
For specifications see details on page
60. For purchasing information see Spare Parts on page
66.
For information on how to calculate the required number of battery modules see Battery
Module Selection on page
64.
Low Voltage Disconnect (option)
If fitted, the Low Voltage Disconnect (LVD) will disconnect all battery modules at the end of
the battery runtime. This is to prevent damage from deep discharge which may shorten the
battery service life.
An audible click will be heard when the LVD operates or releases (whether or not battery
modules are connected). This is normal.
For further information refer to Low Voltage Disconnect (LVD) in the System Controller
Operation Handbook (see Related Information on page
i).
