Wiring Method

J
Use the following procedure to connect wires to the terminal block.
1. Loosen the terminal screws with a thin-slot screwdriver.
2. Insert the wires from underneath the terminal block.
3. Tighten the terminal screws firmly.
Strip the end for
5.5 mm if no
solderless ter-
minal is used.

Connecting Wires to Terminal Block

Wiring Precautions

1. Separate PG Speed Control Card control circuit wiring (terminals TA1 and TA2) from main circuit wiring
and other high-power lines.
2. Use twisted-pair or shielded twisted-pair cables to connect the PG to prevent operating faults. Process
cable ends as shown in Figure 3.32. The maximum cable length is 100 m.
Connect to terminal
TA3 on the VS-616G5.

3. Connect the shield to the ground terminal.
4. Do not solder the wires to the control circuit terminals. The wires may not contact well with the control
circuit terminals if the wires are soldered.
5. The end of each wire connected to the control circuit terminals must be stripped for approximately
5.5 mm.
