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.
Fig. 7 Securely Anchor the Controller
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. 8a) 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
(Fig. 8 b) extending from the main ground bus
or ground pad to each controller
compartment.
