Installation and Configuration
Mounting the Charger
12
CHG-75 PN 51315:A 08/01/01
2.3.4 Ground Fault Detection Disable
Cut jumper
JP2
to disable reporting of a local ground fault condition. The charger’s
ground fault detection circuit might be disabled when the charger is connected to
equipment with its own ground fault detection circuit to prevent
competition
between
the two circuits. Note that Ground Fault detection is required in Canada. Refer to
Figure 2.1 on page 10, for location of the jumper.
2.3.5 AM-1 Ammeter Enable
Cut jumper
JP5
to enable the operation of the AM-1 Ammeter when installed on the
CHG-75 charger. Refer to Figure 2.1 on page 10, for location of the jumper.
2.4 Mounting the Charger
2.4.1 Mounting the Charger in an FACP
The CHG-75 can be mounted in the bottom of the MS-9600 backbox, using the self-
tapping screws included with the charger. In a similar fashion, the supplied nuts can be
used to mount the charger to pem studs located in the bottom of the MS-9200 backbox.
A separate battery box must be used to house the batteries when employing these
configurations. Figure 2.3 illustrates the CHG-75 mounting location in the MS-9600.
The pem studs are located in the same area in the MS-9200 backbox .
Note: The CHG-75 must be mounted in the same room and within 20 feet of the FACP
.
