Maintenance

This topic provides the user with detailed instructions on the removal and replacement of modules within
the drive assembly and amplifiers. A faulty combiner must be replaced. When removing or refitting
modules, observe antistatic handling precautions. Do not change any potentiometer (or link) settings
unless detailed in these instructions. Potentiometers have been set using specialist equipment.

To remove Molex KK type connectors:

❑

Free the locking mechanism on the connector by moving one side of the connector up, then move
the other side up (see Fig 29). The upward motion should only be as far as needed to free the
locking mechanism

❑

DO NOT pull the cable to free the connector

❑

Note that KK type connectors are designed to be removed in this manner to free the locking
mechanism. Do not use this procedure with non-KK type connectors as damage to the connector
may occur.

The following tools, materials and test equipment should be made available to complete the maintenance
tasks described in this topic.
