Vision120 OPLC™ User Guide
We recommend that you use crimp terminals for wiring; use 26-14 AWG wire for all wiring
purposes.
1. Strip the wire to a length of 7±0.5 mm (0.250–0.300 inches).
2. Unscrew the terminal to its widest position before inserting a wire.
3. Insert the wire completely into the terminal to ensure a proper connection according to
the figure below.
4. Tighten enough to keep the wire from pulling free.
Earthing the Power Supply
To maximize system performance, avoid electromagnetic interference by
•
Mounting the controller on a metal panel.
•
Earthing the controller's power supply: connect one end of a wire, 14 AWG, to the
chassis signal; connect the other end to the panel.
Note: The wire used to earth the power supply must not exceed 10 cm in length. If your
conditions do not permit this, do not earth the power supply.
