Stranded copper wire should be checked for all strands inside the

terminal opening.

If a neutral wire connection is required for the connection grid to

make sure the neutral wire is securely connected to the neutral

terminal. Loose neutral wire connection will result in incorrect grid

voltage detection.

NOTICE!

AVIS!

– Connect the Neutral wire to the “N” screw terminal (B), and using a torque wrench,

tighten the screw terminal to to 10.5 in-lbs (1.2 Nm) of torque.

– Connect L1 wire to the “L1” terminal (D), and using a torque wrench, tighten the screw termi-

nal to to 10.5 in-lbs (1.2 Nm) of torque.

– Connect L2 wire to the “L2” terminal (C), and using a torque wrench, tighten the screw termi-
