Basic Installation and Operation Guide
JK Series 720 Controllers

Mounting
Each shipping section must be leveled and firmly secured to its supporting
foundation. Steel shims may be used for final leveling (Fig. 6), if necessary.
When three or more shipping sections are to be arranged in one
continuous line-up, the center shipping section should normally be located
first.
Follow the equipment outline drawings to determine the location of the
mounting bolt holes and any conduit locations.
Fig. 6 Leveling Using Shims
Various methods may be used to anchor the enclosure to the foundation,
including expandable inserts or “J” bolts embedded in concrete. The
recommended size for anchor bolts is 1/2” (Fig. 7).
For heavy equipment, enclosure must be
securely anchored to prevent tipping over.
Additional Cabinet Entries
If conduit entry locations are required in areas other than the removable
plates, cover the electrical assemblies to prevent metal filings from
becoming lodged in areas which may cause a reduction in the high voltage
clearances or a short circuit. After the work is completed, thoroughly clean
the area and inspect the unit for foreign material.

Ground Connections
The controller line-up must be grounded in accordance with
the requirements of the National Electrical Code. Proper
equipment grounding must be established before making any
incoming power connection. If a main ground bus (Fig. 8) is
furnished, make the ground connection to this bus. If there is
no ground bus, the sections which are shipped separately
should be connected to ensure a continuous grounding path.
Each section contains a vertical ground bus extending from
the main ground bus or ground pad to each controller
compartment.
