●
Use a shielded cable for the cable connection.
For the shield part of the shielded cable twist the end out, crimp it with a round terminal, and connect it to the functional earthing screw.
After crimping it with a round terminal, wrap it with insulating tape so there are no spaces and adjust it so the shield part does not touch
any live parts.
CAUTION
Be sure that the shield part of the shielded cable does not touch the terminal block or any live parts.
Failure to do so may lead to electric shock or fire.
