CONTROL BOX FOR A TWO MOTOR BOAT LIFT
INSTALLATION INSTRUCTIONS
1. Mount the control box vertically to a well-supported structure. The enclosure door hinge
should be on the left side when facing the control box.
2. Securely fasten the control box in place using four (4) 1/4" diameter fasteners (not included).
3. To prevent damage to the enclosure, maximum recommended fastener torque is 60 in-lbs.
4. Turn off main power at the primary disconnect. Warning/aVErtissEMEnt/adVErtEncia: RISK OF ELECTRIC
SHOCK! More than one disconnect switch may be required to de-energize the equipment before servicing!
5. Release the metal clasps and open the control box. Remove the four cover screws and
move the front panel so the terminal blocks are accessible.
6. Bring 115 VAC input power into the box through 3/4" conduit. Use a NEMA 3, 3R, 12, 13 conduit connector
for 3/4” conduit. Use 30 AMP (maximum) overload protection to the input power connections.
7. Strip the wires 1/4".
8. Insert the black line wire into the large terminal block marked “INPUT POWER”. Refer to wire diagram.
Tighten the screw to 7.0 in-lbs.
9. Insert the white neutral wire into the isolated neutral bus bar marked “NEUTRAL”. Refer to wire diagram.
Tighten the screw to 14 in-lbs.
10. Insert the ground green or bare wire into the non-isolated ground bus bar marked “GROUND”. Refer to wire
diagram. Tighten the screw to 14 in-lbs.
11. Do not insert more than one wire into a single wire location.

move the front panel so the terminal blocks are accessible.
14. Remove the white jumper wire between large terminal block and isolated neutral bus bar. Refer to wire diagram.
15. Bring 230 VAC input power into the control box through 3/4” conduit. Use a NEMA 3, 3R, 12, 13
conduit connector for 3/4” conduit. Use 30 AMP (maximum) overload protection to the input power connections.

17. Insert the black line 1 wire into the large terminal block marked “INPUT POWER”. Refer to wire diagram.
Tighten the screw to 7.0 in-lbs.
18. Insert the red line 2 wire into the large terminal block marked “INPUT POWER”. Refer to wire diagram.
Tighten the screw to 7.0 in-lbs.
19. Insert the white neutral wire into the isolated neutral bus bar marked “NEUTRAL”. Refer to wire diagram.
Tighten the screw to 14 in-lbs.
20. Insert the green or bare ground wire into the non-isolated ground bus bar marked “GROUND”. Refer to wire
diagram. Tighten the screw to 14 in-lbs.
21. Do not insert more than one wire into a single wire location.
22. Bring conductors from motors into the control box through 3/4” conduit. Use a NEMA 3, 3R, 12,
13 conduit connector for 3/4” conduit. Maximum allowable wire size is to be 10 AWG.
23. Strip the wires 1/4”.
24. Insert the orange, black, and red wires from each Motor color-to-color into the spaces on the large terminal
strip marked “MOTOR #1 OUT” and “MOTOR #2 OUT” on the wire diagram. Tighten the screws to 7 in-lbs.
25. Insert the white wires into the isolated neutral bus bar marked “NEUTRAL”. Refer to wire diagram.
Tighten the screw to 14 in-lbs.
26. Insert the ground wires into the non-isolated ground bus bar marked “GROUND”. Refer to wire diagram.
Tighten the screw to 14 in-lbs.
27. Do not insert more than one wire into a single wire location.
28. Bring the limit switch wires into the control box through 3/4” conduit. Use a NEMA 3,
3R, 12, 13 conduit connector for 3/4” conduit.
29. Strip the wires 1/4”.
30. Insert wire for the upper limit switch into the small terminal block marked “UPPER LIMIT”.
Refer to wire diagram. Tighten the screw to 4.4 in-lbs.
31. Insert wire for the lower limit switch into the small terminal block marked “LOWER LIMIT”.
Refer to wire diagram. Tighten the screw to 4.4 in-lbs.
32. Insert the common wire from the 3-wire limit switch into the small terminal block marked “COMMON”.
Refer to wire diagram. Tighten the screw to 4.4 in-lbs.
33. Do not insert more than one wire into a single wire location.
33. Turn off main power at the primary disconnect. Warning/aVErtissEMEnt/adVErtEncia: RISK OF ELECTRIC
SHOCK! More than one disconnect switch may be required to de-energize the equipment before servicing!
34. Bring the black line, white neutral, and green or bare ground wires from the auxiliary device into the control
box through 3/4” conduit. Use a NEMA 3, 3R, 12, 13 conduit connector for 3/4” conduit.
35. Strip the wires 1/4”.
36. Insert the black wire into the small terminal block marked “AUX OUT”. Refer to wire diagram.
Tighten the screw to 4.4 in-lbs.
37. Insert the white wire into the isolated neutral bus bar marked “NEUTRAL”. Refer to wire diagram.
Tighten the screw to 14 in-lbs.
38. Insert the ground wire into the non-isolated ground bus bar marked “GROUND”. Refer to wire diagram.
Tighten the screw to 14 in-lbs.
39. Do not insert more than one wire into a single wire location.
40. Re-install the front panel.
41. Apply 10 in-lb. torque to front panel fasteners.
42. Turn on main power at primary disconnect.
43. Test all functions of the control box prior to use.

NOTE:
When re-installing the
front panel using the
four fasteners, inspect
and ensure that wires
from front panel are
not positioned near the
top of the contactors.
• Read operating instructions before attempting to use.
• Maintain visual contact with the vessel while lift is in operation.
• Allow lift to come to a complete stop before reversing direction.
• Check all motors to see if running in proper direction.
• Turn power off when not in use.
• Do not lift or lower vessel while vessel is occupied.
• Ensure lift is fully lowered before attempting to dock.
• Keep enclosure door closed when lift is not in use. Use of a lock is recommended to prevent tampering.
