coating) conduit fitting should be attached in the strain relief
hole. Moisture should not be allowed to penetrate the motor
base enclosure as it could damage the components inside.

10. Keep the lead length inside the enclosure to no longer than 4

inches to maintain good EMC performance. The distance from
the opening in the conduit fitting to the filter should remain
less than 10 cm (4 inches). Excessive wire length can render
the power filter useless.

11. Insert the end of the new cord into the enclosure through the

conduit fitting. Solder the new hot and neutral wires to the
corresponding terminals. Insulate the connections either with
heat shrink tubing as they were before or with electrical tape.

12. Reconnect both protective earthings, with one terminal ring per

grounding point. Remember to include the external tooth lock
washers between the terminal ring and the enclosure body
when inserting and tightening the screws.

CAUTION Properly terminate the safety ground wires in the
positions provide for connection of the protective earth
conductor.

13. Tilt the power filter back into place, align the holes on the

enclosure with the holes on the filter plate, insert and tighten
the four screws that hold the filter in place.

14. Carefully slide the circuit board back into the enclosure, taking

care not to pull any wires loose, or leave any wires under the L-
shaped bracket. Secure the board and bracket on the base of the
enclosure using the two screws you removed earlier.

15. Next, slide the front panel back into place and reinsert the ten

screws that secure it in place. Do not forget to reattach the P-
clip that is held in place by one of the screws.

16. Finally close the lid, move the clamps that secure it into place,

and tighten the screw in each clip to firmly seal the lid in place.

CAUTION Prior to applying power, check the position of the
voltage select switches on the front of the enclosure.
