5.3 Battery
The external backup battery is connected between
Batt Gnd
(-) and
Batt +24V
(+) on the con-
nector marked
Battery
on
CI 1376
.
A 16Ah battery gives approximately six hours backup time with 5-8 hours charging time
dependent on model. For longer backup time an external charger is required to be able to
charge the battery within a reasonable time. An external battery protection circuit (like Nor-
marcs
BP 543
) has to be connected between the
Ext. Charger
(+) and
BATT GND
(-) input. In
addition
Mains
directly on
NM 7050
has to be disconnected. Figure 5-4 shows the connec-
tions schematically.
