If a LonWorks option card is present, leave all the wires connected to the option card, disconnect the option card ground wire
at the Drive end and remove the option card from the Drive.

The power terminal block for the three phase input and output power connections is not removable. All connections to the
power terminal block must be removed. Do not overlook the Drive ground wire. It is behind other wiring and will probably be
removed last. Observe the wire and terminal markings for all power wires, to ensure correct re-wiring to the new Drive. The
wires are labeled from the factory, but re-label any wires where labels may no longer be legible. Refer to Chapter 2 Electrical
Installation and the schematic diagram that was shipped with the original Bypass unit.
Once all wiring has been disconnected from the Drive, the Drive is ready to be removed from the enclosure.
Drives located in Bypass units are mounted differently than stand alone drives. A Drive in a Bypass unit is mounted such that
the heat sink is external to the enclosure. Mounting brackets are located on the top and bottom of the Drive, between the Drive
and the Drive's heat sink. These brackets are bolted to the Bypass back panel with the heat sink projecting through an opening
in the back panel.
