1.3.5 Connection to Battery
Before starting on this point please read the section 1.3.8.3 in this manual about Battery
attachment.
The BS may be connected to a 48V battery, which the BS can charge.
The Base Station is prepared for –60V battery operation, wherefore a switch is placed on the
back plane of the BS to indicate to the PS411’s, whether a –48V or –60V battery is used.
Note that the present version of PS411 can only operate with –48V DC, wherefore this
feature is not active, and the switch shall be placed in the –48V position.
The Switch is accessible by removing the PS411 Power Supplies.
