2.9.2 Connecting the Charger to an MS-9200
The charger can be connected to an FACP power supply, such as an MS-9200, by
disabling the local charger. The MS-9200 charger is disabled by cutting jumper JP1.
WARNING! Do not attempt to connect the CHG-75 to older versions of the MS-9200
FACP main circuit board, which does not allow disabling of the FACP battery charger
(no JP1 jumper). System damage will result.
To connect a charger to the MS-9200:
1. Disconnect all power (AC and DC) from the MS-9200 and CHG-75
2. Cut jumper JP1, which is located on the MS-9200 main circuit board, to disable
the FACP battery charger
3. Disconnect the battery ends of the battery cable connected to J2 on the MS-9200.
Cut off the battery connectors and strip the ends of the wire.
4. Connect the stripped wire ends to the CHG-75 Output Circuit TB2, Terminal 3
(Out +) and Terminal 4 (Out -) as illustrated in Figure 2.13. Be certain to observe
proper polarity.
5. Connect the batteries to the charger (refer to Figure 2.10 and Figure 2.11).
