Note! Terminals 3, 6, and 9 are at the same potential.
Note! For safety reasons the fault relay signals a "fault" when the ACS550 is
powered down.
You can wire the digital input terminals in either a PNP or NPN configuration.

Checking Motor and Motor Cable Insulation

Warning! Check the motor and motor cable insulation before connecting the
drive to input power. For this test, make sure that motor cables are NOT
connected to the drive.
1. Complete motor cable connections to the motor, but NOT to the drive output
terminals (U2, V2, W2).
2. At the drive end of the motor cable, measure the insulation
resistance between each motor cable phase and Protective
Earth (PE): Apply a voltage of 1 kV DC and verify that
resistance is greater than 1 Mohm.
