Step Action for Voltage Imbalance Mid-String Monitoring
1 Insert one RJ-45 end of the 848652947 wire set into the P5-SYS AUX PORT on the controller and
the other end to the first ES771A Remote Voltage Monitor module.
2 Follow the steps for installing a probe described in the previous section to attach a VT probe to
the negative post located at the center of the string as depicted in Figure 15.
Do not cut the brown wire.
3 Dress and attach the snap fit connector on the brown wire to the appropriate snap fit pin on the
ES771A (J1-J3).
Note: exercise care when attaching the battery voltage sense wire onto the J1, J2, and J3 pins of
the ES771A pins. These push-on clips can be deformed if excessive force at an incorrect angle of
insertion resulting in a non-optimum connection. The contact must not be bent more than 10
degrees.
4 Verify that the controller automatically registers the number of ES771A modules (1) at the front
