a) Method 2A

Capacitors are reformed by switching in a rectifier and resistor circuit, which is connected

to the drive input. The reforming circuit is given in figure 2 below. Circuit component

values for different voltages are given in table 1. See the reforming time in figure 1.

WARNING: Disconnect the mains supply while the reforming circuit is connected.

Note! Markings for drive input differs between drive types:

ACS550

U1 V1 W1

ACS150/310/320/350/355

U1/L V1/N W1

ACS50/55

L/R N/S
