.11.2 Connecting Main Power
There are two possibilities for connection:
1. AC SOURCE RECOMMENDED
Connect the AC power supply cable to the AC1, AC2 and PE terminals of the main power connector.
Notes for connecting the AC power cable:
 The source of the 0 ~ 62 VAC Power Supply must be isolated.

For the greatest immunity, a shielded (not twisted) cable is recommended (not
mandatory) for the AC power supply cable. A 3-wire shielded cable should be used.
The gauge is determined by the actual current consumption of the motor.

Connect the two power wires (Neutral and Phase) to the AC power leads of the source.
For safety requirements, the third wire must be used for the protective earth connection
(connected to the PE terminal).
