5. The control relay PCB assembly inside the enclosure is
connected to the enclosure via an L-shaped bracket. It will be
necessary to remove the mounting screws which hold the
bracket to the bottom of the housing in order to gain access to
the wires connected to the base of the filter. Do not disconnect
wires from the relay assembly. Locate the two screws that
secure the L-shaped bracket in place, loosen and remove them.
Then
CAREFULLY
slide the circuit board assembly and the
bracket upwards so the unit rests on top of the encoder
assembly. Do not yank or force the circuit board while pulling
it upward as rough handling will likely loosen or damage the
internal wiring of the motor base.
6. Remove the two screws that secure the protective earth wires to
the enclosure, so you can gain access to the bottom terminals
on the power filter. Note the toothed washer between each
terminal ring and the enclosure body as these will need to be
replaced in the same location when it is time to reassemble the
unit.
7. Using a Phillips head screwdriver locate and remove the four
screws on the side of the enclosure by the belt tension idler,
this will release the power filter from the side of the enclosure.
Do not attempt to pull the power filter out of the enclosure as it
is connected to several wires in the unit. Without disconnecting
the wires from the top of the filter tilt the filter so you can
access the terminals on the base.
The electrical wiring color code used by ETS-Lindgren for this
unit is:

Protective Earth/Safety Ground
8. Note which terminal is hot and which one is neutral. Remove
the heat shrink tubing and unsolder the hot and neutral
terminals. Remove the power cord from the enclosure.
9. The strain relief is properly sized for a standard ½ inch
electrical conduit fitting. If the unit will be exposed to moist
environmental conditions an appropriate metal (with rubber
