Figure 12-5 shows the connections required if load protectors are the DIN style circuit breakers. Note
that 10 alarm inputs are provided for monitoring up to 10 DIN breakers because these breakers must
be monitored individually. The DIN CB(1-10) inputs are alarmed on an open to VBus(-).
J100 and J101 Serial Ports
J100 and J101 are used to connect the ES772A to the QS840A controller. Note that if QS873A VT-Probes
are to be used in conjunction with the ES772A, connect J100 or J101 on the ES772A to the controller via
the Auxiliary Port connector on the QS840A controller, and then connect the QS873A to the unused
RJ-45 jack on the ES772A.
If the ES772A is being used with both the QS873A and the ES771A Remote Voltage Monitoring Module,
connect either the ES771A or the QS873A to the QS840A controller as both have two RJ-45 jacks for
serial communication purposes. Then connect the two-jack device not connected to the controller to
the unused serial port of the two-jack device connected to the controller, and connect the QS873A to
its second serial port.
ES772A Module Mounting
Use the template in Figure 12-6 as a guide to mount the ES772A in your application. The location of the
mounting holes MH1 and MH2 are outlined.
