The door on the rectifier section of
F-Frame VLTs are fitted with a
feed-through hole to accommodate
a USB extension cord so that the
controls can be accessed from a
laptop computer without requiring
access to the inside of the VLT.
With the rectifier door open, the
hole is located near the upper right
corner of the door. See Figures 1
and 2.
The feed-through hole is covered
by the decorative label on the out-
side and with a round sticker on the
outside.

WARNING
The frequency converter contains dangerous voltage. Disconnect power and follow lock-
out/tag-out procedures before working on this equipment.
