XIII.1.E. BATTERY CONNECTION
XIII.1.E.1. THE WALL-TYPE SYSTEM
Since any power failure would prevent the exchange from functioning normally, in case that
is probable, a battery should be connected to the exchange. After SPS200 is installed, the
battery connection of the exchange is made. The battery switch of the exchange is supposed
to be at “0” position while connecting. Two connection clips are available on SPS200 for
battery connection. It is strongly recommended to connect to those clips a 48V 24Ah dry
battery set (12V, 24Ah X 4.) The red end is supposed to be connected to the “+” pole of the
battery set, whereas the black end to the “-“ pole. To make the connection, the
corresponding end of the battery cable is inserted into the hole in front while the spring latch
of the clips is being pressed, up to a point that is deep enough so that no naked segment of
the cable is left outside and then the latch is released.
Regarding the systems with two racks, the battery connection is made to the SPS200 of the
main rack only, whereas no connection is made to the second SPS200.

REVERSE BATTERY CONNECTION MAY DAMAGE YOUR EXCHANGE!
The batteries should be placed in the lower section of the exchange, on an elevated surface,
so that they do not touch the floor. The cables that are to be pulled to the system must
definitely be run by a special cable conduit.
XIII.1.E.2. THE CABINET-TYPE SYSTEM
*
THE EXCHANGE FAILS TO FUNCTION IN CASE OF POWER FAILURE.
THEREFORE, A BATTERY MUST BE CONNECTED TO IT IF THERE IS SUCH A
PROBABILITY.
*
THE BATTERY BREAKER MUST BE OFF DURING THE CONNECTION
OPERATION.
Dry type batteries are used in the system. The batteries are placed on the bottom surface of
the DS200 cabinet. The compartment has been designed so high as 38 Ah dry type batteries
can fit in. The dimensions of the cabinet bottom surface are about 60x78 cm. That space is
capable of housing at most12 batteries of 24 Ah (width: 17.5 cm, length: 16.6 cm, height:
12.5 cm) or of 38 Ah (width: 16.5 cm, length: 19.7 cm, height: 17.0 cm).
It is considered that at least 4 batteries would be employed in a system with three racks and
there is room in the cabinet for 8 or 12 batteries, as needed. Placing the batteries close to
the back cover facilitates connection, as well as maintenance.
