External devices are wired to a terminal strip connector at
the back of the MJ-5 Control Panel. See Appendix K for
pin-outs and signal descriptions.
Hazardous voltage will be present on
various control leads when regulator is
energized.

Field Maintenance:
The MJ-5 is a state-of-the-art controller utilizing complex
circuits and sophisticated components for the detection,
processing and display of regulator parameters and the
precise control and operation of the tap changer. Field
maintenance is not recommended as special equipment and
instrumentation are required for the proper calibration,
testing and checking of the controller operation. It is
strongly recommended that MJ-5 controller repair, testing,
and calibration be performed only by Siemens authorized
repair facilities.
