[Wiring Precautions]
!
CAUTION
Use applicable solderless terminals and tighten them within the specified torque range. If any
spade solderless terminal is used, it may be disconnected when the terminal screw comes
loose, resulting in failure.
Tighten the connector screws 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, fire, or
malfunction.
Connectors for external devices must be crimped with the tool specified by the manufacturer,
or must be correctly soldered. Incomplete connections may cause short circuit, fire, or
malfunction.
When disconnecting the cable from the module, do not pull the cable by the cable part.
For the cable with connector, hold the connector part of the cable.
Pulling the cable connected to the module may result in malfunction or damage to the module
or cable.
Prevent foreign matter such as dust or wire chips from entering the module. Such foreign
matter can cause a fire, failure, or malfunction.
A protective film is attached to the top of the module to prevent foreign matter, such as wire
chips, from entering the module during wiring. Do not remove the film during wiring. Remove it
for heat dissipation before system operation.
