INPUT / OUTPUT WIRING
Wiring Requirements
NOTE:
When attaching two or more wires to the same
terminal, other than 14 AWG (2.0 mm
improper electrical contact.
Each terminal can accommodate the following gauge of wire:
• Single wire: From 22 AWG (0.3 mm
• Multiple wires: Up to two 18 AWG (1 mm
•
Prepare wiring for the terminal blocks, as follows:
•
Strip 1/2 in. (13 mm) insulation from the
conductor.
•
Cut a single wire to 3/16 in. (5 mm). Insert the wire in the required terminal location and tighten the screw.
•
If two or more wires are being inserted into one terminal location, twist the wires together with a minimum of
three turns before inserting them.
•
Cut the twisted end of the wires to 3/16 in. (5 mm) before inserting them into the terminal and tightening the
screw.
•
Pull-on each wire in all terminals to check for good mechanical connection.
NOTE:
Do not over-tighten the terminal screws to avoid deformation and damage to the terminal block.
The maximum torque for the terminal screws is 4.4 in-lb (0.5 Nm).
