The MA remote controller cannot be used at the same time or interchangeably.
Ensure that the wiring is not pinched when fitting the terminal box cover. Pinching the wiring may cut it.
Use wire with supplemental insulation.
Input to TB142A, TB142B, and TB142C should not carry voltage.
Cables from equipment connected to external input/output should have supplemental insulation.
Use a single multiple-core cable for external input/output to allow for connection to the PG screw.
Wire the power supply so that no tension is imparted. Otherwise disconnection, heating or fire result.
