XIII.2. DS200S & DS200M
XIII.2.A. SPS200M AC/DC AND DC/DC POWER
SUPPLY
The SPS200M Power Supply, which contains the SPS200MCR Power Card, has been
mounted in a metal chassis.
In order to place SPS200M in the rack, the metal rails which are on the power chassis should
be inserted smoothly into the metal slots that are on the rightmost section of the rack. Then,
the SPS200M should be pushed into the rack until the connector on the back of the power
rack is firmly plugged into the corresponding connector on the BPL200S/M-SPS Backplane.
In case it is necessary to take SPS200M out of the rack, the battery and mains ON/OFF
switches that are on the SPS200M module have to be set to OFF, starting with the one on
the battery. The 230 V cable, battery connection cables and fixing screws, if they are
present, should be detached. Then, the power supply should be pulled out.
XIII.2.B. BATTERY CONNECTION
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 SPS200M 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 SPS200M 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. 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 to complete the connection.

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.
