Use a shielded cable for the cable connection.
●
Twist out the end of the shielded part of the cable, crimp it with a round terminal, and connect it to
After crimping it with a round terminal, wrap it with insulating tape so there are no spaces and adjust it so the shielded part does not
come into contact with any live parts.
Be sure that the shielded part of the cable does not come into contact with the terminal block or any live parts.
CAUTION
Failure to do so may lead to electric shock or fire.
When connected to the forced stop input
With the Forced Stop input, it is possible to override air conditioning operations to force a stop when signals are received from fire
alarms, etc.
