[Wiring Precautions]
CAUTION
●
Connect circuits isolated from hazardous voltage by double/reinforced insulation to terminal blocks or
power connectors.
●
Individually ground the GND wires of the safety extension module with a ground resistance of 100
Ω
or less.
Failure to do so may result in electric shock or malfunction.
●
Check the rated voltage and terminal layout before wiring to the module, and connect the cables
correctly.
Connecting a power supply with a different voltage rating or incorrect wiring may cause a fire or
failure.
●
Tighten a terminal screw within the specified torque range.
Undertightening can cause short circuit, fire, or malfunction. Overtightening can damage the screw
and/or module, resulting in drop, short circuit, or malfunction.
●
Mitsubishi safety extension module must be installed in control panels. Connect the main power
supply to the safety extension module through a relay terminal block.
Wiring and replacement of an external power supply must be performed by qualified maintenance
personnel who is familiar with protection against electric shock. For wiring methods, refer to Page 89
WIRING.
●
When using the safety extension module under the severe noise environment, take noise reduction
measures such as using a surge absorber and a ferrite core.
