2.3.3 General Wiring Guidelines
 ControlWave GFC Plus terminal blocks use compression-type
terminals that accommodate up to #16 AWG wire.

When making a connection, insert the bare end of the wire (approx
¼” max) into the clamp adjacent to the screw and secure the screw.

To prevent shorts, ensure that no bare wire is exposed. If using
standard wire, tin the bare end with solder to prevent flattening and
improve conductivity.
 Allow some slack in the wire while making terminal connections.
Slack makes the wires more manageable and helps minimize
mechanical strain on the terminal blocks.
