3.3 Wiring Guidelines
3.3.1 Main considerations
1 Tightening Torque for Screw terminals：Refer to the tables 3-1, when using a
screwdriver or any other suitable tools to make connections.
2 Power terminals:
Single phase : L1 (L), L3 (N)
Three-phase 200V models: L1 (L), L2, L3 (N)
400V models: L1, L2, L3
3 For all cabling use copper wires and the cable size shall be according to the table
below rated at 40 degrees Celsius.
4 Power & Control cable Minimum rated voltage
240V AC system, 300V AC.
480V AC system, 600V AC.
5 Control cables should be separated from the power cables. Do not place them in the
same cable tray or cable trunking to prevent against electrical interference.
