①
Module appearance
Check the module case for flaws, cracks and other defects. Defects in the module case
may be a sign of damaged internal circuitry, causing the system to malfunction.
②
Indicator status of illumination and indication
Check the indicators for unusual status.
③
Mounting screw and terminal block screw tightness
Check the screws, such as those used to mount the module and the terminal block screws,
for tightness.
If found loose, tighten them fully. Loose screws could cause the system to malfunction or
get burnt under heat.
④
Cable and wire covering status
Check the cable and wire coverings for defects and abnormal heat. Coverings out of
position or heated coverings could cause the system to malfunction, threatening electrical
shock hazards and getting the system burnt due to shorts.
⑤
Dust adhesion
Check to see if the module has not caught dust. Remove dust adhering to the module
using a vacuum cleaner. Adhering dust could cause a short in internal circuitry, causing
the system to get burnt.
CAUTION
The module is susceptible to electrostatic damages. Discharge electrostatic
charges from your body before setting switches, attaching or detaching cables, or
inserting or removing connectors.
