Wiring Precautions

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 3.18. The maximum cable length is 100 m.

Do not connect here.

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.
