2.3Main power Connection
The main power cable should be routed into the bottom left conduit entry.
Macurco recommends a minimum wire size of AWG18. The modular connector will accept wire from 12 to 24 AWG.
The safety ground wire should be secured to the ground stud at the bottom left of the cabinet with the lock washer and nut supplied. Macurco recommends the use of a ring terminal for the ground connection.
Refer to Table
The line and neutral wires should be stripped 1/4 in. (6.5 mm), insert the wire into the wire cavity of the modular connector and tighten the screw clamp. Ensure that the wire cannot be easily pulled from the connector. Plug the modular connector into J4 on the PCB and ensure that it latches into the header properly.
