After the batteries that are in the shelf under the exchange are serially connected to one
another, the set is connected through the main battery breaker to the battery input of the
main rack, which is the lowermost rack. The battery output is attached to the connection clips
on SPS200 in the manner as the red end corresponds to the “+” pole, and the black end to
the “-“ pole. No battery connection is required for the other SPS modules.

REVERSE BATTERY CONNECTION MAY DAMAGE YOUR EXCHANGE.
The provide 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.
Since the battery is been connected to the 48 VDC output of the SPS200 in parallel, a
completely exhausted battery group creates adverse effects on the exchange, as long as
proper operation is concerned. In order to prevent such a situation, the battery group must be
charged through an external supply and be connected to the system again.
*
REGARDING THE SYSTEMS WITH BATTERY CONNECTION, THE
EXCHANGE FAILS TO OPERATE PROPERLY IN CASE OF FAILURE IN 230 VAC
MAINS SUPPLY DURING NIGHT TIME AND HOLIDAYS.
*
THE SYSTEM IS AUTOMATICALLY SHUT DOWN IF THE BATTERY
VOLTAGE DROPS BELOW 34 VDC DURING PROLONGED POWER FAILURES,
AND THE BATTERIES ARE NOT SWITCHED ON UNTIL THE BATTERY VOLTAGE
LEVEL REACHES 46 VDC.
