Specifications of Control Terminal
Wire Gauge: 26~16AWG (0.1281-1.318mm
2
)
Torque:
Ⓐ
5kg-cm [4.31Ib-in.] (0.49Nm) (As shown in figure above)
Ⓑ
8kg-cm [6.94Ib-in.] (0.78Nm) (As shown in figure above)
Wiring precautions:

Properly install signal & control cable into the terminal; fasten the installation by a
slotted screwdriver. If the wire is stripped, sort the wire before install into the terminal.
Noted that bare signal cable should reserve at least 5mm to prevent from occurring
bad connection and signal cable comes off.

Flathead screwdriver: blade width 3.5mm, tip thickness 0.6mm

In the figure above, the factory setting for S1, SCM is short circuit. The factory setting
for +24V-COM is short circuit and SINK mode (NPN); please refer to Chapter 4
Wiring for more detail.
