Siemens Industry, Inc.
Barrier Terminal Strips
Terminal contacts on the back of the MJ-5 Control Panel
allow for external control over certain functions such as
VRC activation and tap changing. These terminals can be
used to provide an electrical interface to a SCADA system
for remote control applications and/or other desired control
functions.
1.3 Mounting on Siemens Regulators
The MJ-5 Control Panels are mechanically and electrically
compatible and interchangeable with earlier MJ, IJ and SJ
series and earlier control units. They can be mounted in the
existing enclosure by simply swinging the control to be
replaced outward on its hinges, disconnecting the polarized
disconnect switch (PDS), then removing the unit and
inserting the new unit (see Appendix B).
1.4 Mounting on Cooper Regulators
A retrofit kit is available for mounting the MJ-5 Control
Panels on Cooper regulators. The kit includes all of the
necessary hardware and a set of complete instructions for
mounting and connecting the MJ-5 to the regulator. The
retrofit is accomplished without the necessity of replacing
the waterproof housing. See the Retrofitting Cooper
Regulators Application Note for details. Contact your
Siemens representative for ordering information.
1.5 Mounting on GE Regulators
A retrofit kit is available for mounting the MJ-5 Control
Panel on GE regulators. The kit includes all of the
necessary hardware and a set of complete instructions for
mounting and connecting the MJ-5 to the regulator. The
retrofit is accomplished without the necessity of replacing
the waterproof housing. See the Retrofitting GE Regulators
instruction manuals in Appendixes O and P.
Contact your Siemens representative for ordering
information.
1.6 Mounting on Load Tap Changers
A retrofit kit is available for mounting the MJ-5 Control
Panels on LTCs. The kit includes all of the necessary
hardware and a set of complete instructions for mounting
and connecting the MJ-5 to the LTC.
Contact your Siemens representative for ordering
information.
