3.0 BACK PANEL & WIRING
The rear views of the M650 are shown in figures 3A and 3B with the option port shown
(removable terminal block at the top), which may be selected at order time, as either,
the serial communication option, the 0-1mA analog transducer output option, or the 4-
20mA analog transducer output option. However, it is also possible to have a meter
without this option port.
See Appendix A1 for detailed wiring diagrams covering the CT/VT measurement
inputs. Refer to the appropriate section in this user manual when wiring either the
serial communication option, or either analog transducer output option, whichever
applies to the option port for your meter.
