•
The MA remote controller cannot be used at the same time or interchangeably.
Note:
Ensure that the wiring is not pinched when fitting the terminal box cover. Pinching the wiring may cut it.
Caution:
•
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.
Caution:
Wire the power supply so that no tension is imparted. Otherwise disconnection, heating or fire result.
