7-2 Periodic Maintenance
Guidelines for the Application, Installation and Maintenance of Solid
State Control”.
Static Sensitive Items – While performing maintenance, special
precautions must be observed in handling or touching certain static
sensitive components in the cabinet. All circuit cards can be damaged
by Electro-Static Discharge. If personnel will make contact with an
ESD sensitive component during maintenance, they must be
grounded. Grounding should be accomplished with a wrist strap
which is connected to an approved ground.
Tests & Records Final Check Out – After maintenance or repair of industrial controls,
always test the control system for proper functioning under controlled
conditions that avoid hazards in the event of a control malfunction.
“Keep Good Maintenance Records” – This rule will be most
helpful in locating possible intermittent problems by pointing to a
particular area of recurring trouble within the overall system. Further,
good maintenance records will help reduce major costly shutdowns
by demanding the use of proper test equipment and an appropriate
inventory of spare parts. For additional information See NFPA 70B,

ATTENTION: Use of other than factory
