PROCEDURE

1.Remove input power to the INVERTEC® V-450 PRO.

2.Using the 3/8” nut driver, remove the case top.

3.Perform the Capacitor Discharge Procedure.

4.Locate the Power Board and plugs J42 and J43. Do not remove plugs or leads from the Power Board. See Figure F.9.

5.Carefully apply input power to the INVERTEC® V-450 PRO.

WARNING

ELECTRIC SHOCK can kill.

High voltage is present when input power is applied to the machine.

6.Turn on the INVERTEC® V-450 PRO. Carefully test for the correct voltages at the Power Board according to Table F.4.

7.If either of the 40 VDC voltages is low or not present at plug J41, check capacitor C3 and the rectifier bridge. See the Wiring Diagram. Also perform the T1 Auxiliary Transformer Test.

8.If any of the DC voltages are low or not present at plugs J42 and/or 43, the Power Board may be faulty.

9.Install the case top using the 3/8” nut driver.
