Cable Installation and the UL Standards

SPI9000 Inverter Unit FI9 – FI14 User Manual

September 2006

To meet the UL (Underwriters Laboratories) regulations, a UL approved copper cable with a minimum heat-resistance of +60/75°C must be used.

The tightening torques of the terminals are given below in Table 3-9.

520	–	920	380 – 500V	FI12	340 (40)
385	–	650	525 – 690V

1030	– 1300		380 – 500V	FI13	340 (40)
920	– 1030		525 – 690V

1600	– 2300		380 – 500V	FI14	340 (40)
1300	– 1900		525 – 690V

Tightening torque of terminal connection to the isolative base.

Note: Apply counter torque to the nut on the other side of the terminal when tightening/ loosening the terminal screw in order to avoid damage to the terminal.

Cable and Motor Insulation Checks

1.Motor cable insulation checks

Disconnect the motor cable from terminals U, V and W of the inverter and from the motor. Measure the insulation resistance of the motor cable between each phase conductor as well as between each phase conductor and the protective ground conductor.

The insulation resistance must be >1MΩ.

2.DC supply cable insulation checks

Disconnect the DC supply cable from terminals B- and B+ of the inverter and from DC supply. Measure the insulation resistance between each conductor and ground.

The insulation resistance must be >1MΩ.

3.Motor insulation checks

Disconnect the motor cable from the motor and open the bridging connections in the motor connection box. Measure the insulation resistance of each motor winding. The measurement voltage must equal at least the motor nominal voltage but not exceed 1,000V.

The insulation resistance must be >1MΩ.
