Important: This procedure requires special equipment and training. Only
qualified and trained personnel should perform these
procedures.
1. Remove power from the drive. Refer to
Drive on page
2. Remove the covers from the power structures. Refer to
Covers from the Power Structures on page
3. On Power Structure #1, visually inspect the pre-charging resistors. If
pre-charging resistors are damaged:
A. Replace the Rectifying Module (See
Output Power Modules and Rectifying Modules on page
B. Check the capacitors, rectifiers and external connections for
short-circuits. (See
C. Check the Output Power Modules (See
and Reverse Biased Diode Tests for Major Power Components on
page
2-4).
