Maintenance
Safety and Preventative The Maintenance Technician should become familiar with the layout and
be aware of the basic system parameters. Only qualified technicians should
be allowed to work with this equipment under competent supervision.
General housekeeping is the key to maintaining power electronic and
electrical equipment. They are to be kept as dust free as possible. A
scheduled program of inspection will reduce the possibility of problems.
Servicing energized industrial control equipment can
be hazardous. Severe injury or death can result from
electrical shock, burn, or unintended actuation of
controlled equipment. Recommended practice is to
disconnnect and lock out control equipment from
power sources, and allow any stored energy in capaci-
tors to dissipate. If it is necessary to work in the
vicinity of energized equipment, the safety related
work practices of NFPA 70E, Electrical Safety
Requirements for Employee Workplaces, must be
followed.
Periodic Inspection Note: For OEM-supplied components, refer to documentation provided by
the OEM for recommended periodic maintenance procedures.
Industrial control equipment should be inspected periodically. Inspection
intervals should be based on environmental and operating conditions, and
adjusted as indicated by experience. An initial inspection, within 3 or 4
months after installation, is suggested. Applicable parts of the following
guidelines should be used:
Contamination
If inspection reveals that dust, moisture or other contamination has reached
the control equipment, the source must be eliminated. This could indicate
an incorrect or ineffective enclosure, unsealed enclosure openings (conduit
or other) or incorrect operating procedures. Dirty, wet or contaminated parts
must be replaced unless they can be cleaned effectively by vacuuming or
wiping.
