Connecting the Charger to an MS-9200 - A charger can be connected to an MS-9200
(requires MS-9200 circuit board #71741, or later) by disabling the local charger by cutting
jumper JP1 as illustrated in Figure 10.
Figure 10 Typical Wiring of a Charger to an MS-9200
WARNING! Do not attempt to connect the CHG-120F to the older version MS-9200 FACP
main circuit board #03317, which does not allow disabling of the FACP battery charger (no
JP1 jumper). System damage will result.
To connect a charger as shown in Figure 10, follow these steps:
Step Action
1
Cut jumper JP1, on the MS-9200 main circuit board (#71741, available June 1, 1998)
only, to disable the FACP battery charger.
2
Cut the battery cable connected to J2 on the MS-9200 and wire nut to wires connected
to the charger output circuit (TB2: Out 1+ and Out 1–) as shown in Figure 10. Be
certain to observe polarity.
3
If needed, connect the battery+ and battery– terminals of an optional external device
to the charger output circuit (TB2: Out 2+ and Out 2–) as shown in Figure 10.
4
Connect the batteries to the charger (for battery connections see Figure 5 or Figure 6).
