8-9. Removing Cover and Measuring Input Capacitor Voltage
!
Turn Off welding power source,
and disconnect input power.
!
Significant DC voltage can
remain on capacitors after unit is
Off. Always check the voltage as
shown to be sure the input ca-
pacitors have discharged before
working on unit.

1
Interconnect Board PC2
2
Voltmeter
Measure the DC voltage across the +
bus terminal and
−
bus terminal on PC2
as shown until voltage drops to near 0
(zero) volts. Measure input capacitor
voltage on both inverter assemblies
before proceeding.

Typical Bleeder Resistor
An example of a typical bleeder resistor
is shown on this page.
Proceed with job inside unit. Reinstall
cover when finished.
Tools Needed:
