result in damage to equipment and
property, and/or injury or loss of life.

Note:

Maximum wire size termination and

torque rating:
• 0.0507 to 3.30 mm2 (30 to 12 AWG)
single-wire termination or two 1.31
mm2 (16 AWG)
• 0.8 Nm (7.0 in-lb.) torque

Note:

Adjacent terminals may be labeled
differently, depending on the model
number.

Note:

To prevent damage to the controller,
do not connect wires to unused ter-
minals.

Note:

Maintain electrical isolation between
digital input-outputs, switched dc/open
