Rockwell Automation 1395 Node Adapter Board - Manual (Page 68)

Chapter 7
Periodic Maintenance
7-2
ATTENTION: Use of other than factory recommended test
equipment for solid state controls may result in damage to the
control or test equipment or unintended actuation of the controlled
equipment.
Static Sensitive Items – While performing maintenance on the 1395 Drive
and the Node Adapter Board, special precautions must be observed in
handling or touching certain static sensitive components in the cabinet. All
circuit cards and SCR’s in the drive 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.
Programming Terminal – The Programming Terminal controls are
non-servicable items that should not be disassembled. If the display face
becomes dirty, it should only be cleaned with a damp cloth. Cleaning
solvents and detergents must not be used to clean the panel. Remote
Programming Terminals should not be subjected to liquid or submerged for
cleaning. Non-operable panels should be returned to the factory for
replacement as a complete unit.
Tests and 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

Electrical Equipment Maintenance,” published by the National Fire
Protection Association.
