Connecting the Actuators to Black Control Box:
1.
Carefully follow the actuator and tab installation guidelines in the Lectrotab Operation and Installation
Manual included in all of our kits.
2.
Once the trim tab plates and actuators have been installed, route the actuator cable to the black control
box and attach the cable to a secure fixture every few inches to prevent the cable from getting caught
on gear and becoming disconnected.
3.
Follow the wiring diagram on the next page to connect the port and starboard actuators to the 12 pin
plug provided (this plug will eventually be connected underneath the black box). Strip a couple inches of
the actuator cable outer black jacket. This will expose a white and black conductor and a plastic vent
tube. The vent tube must not be blocked and must be kept in a high and dry location with the tube
facing downward.
4.
Strip approximately 1/4" (6mm) from each conductor and connect to the green 12 pin plug as follows:
1.
Port Actuator White wire to plug #3 (dual actuators/tab connect white wires in parallel)
2.
Port Actuator Black wire to plug #5 (dual actuators/tab connect black wires in parallel
3.
Starboard Actuator White wire to plug #4 (dual actuators/tab connect white wires in parallel)
4.
Starboard Actuator Black wire to plug #6 (dual actuators/tab connect black wires in parallel
Connecting the Supply Voltage:
1.
The supply voltage must match the actuator voltage.
2.
Route a positive 12 or 24vdc wire and battery negative wire from the fuse panel to the green 12 pin plug
located that will eventually be connected to the black control box. A fuse or breaker must be inline with
the +12 or 24vdc supply wire to the black control box. The fuse sizing is as follows:
1.
12vdc single actuator per tab uses 15 to 20 amp fuse
2.
24vdc single actuator per tab uses 10 amp fuse
3.
12vdc dual actuators per tab uses 35 amp fuse
4.
24vdc dual actuators per tab uses 20 amp fuse
3.
Connect the +12 or 24vdc fused wire to the 12 pin green plug #1.
4.
Connect the battery (-) negative wire to the 12 pin green plug #2.
Connecting the Black Control Box to Display Panel:
1.
Locate the black 6 pin connector on the gray control cable provided.
2.
Plug the black 6 pin connector to the Primary and Secondary Display Panel.
3.
Attach the red wire extending from the Primary Station black 4 pin plug to the ignition key run position
or accessory switch Primary Station Keypad Only. (Do not connect red wire on secondary station.)
4.
Route the cable to the Black Control Box securing the cable every few inches along the way.
5.
Strip a couple inches of the gray outer jacket from the control cable and approximately 1/4" of
insulation from the individual conductors from Primary and Secondary Display cables.
6.
Connect Primary and Secondary control cable wires together in the green 12 pin plug as follows:
1.
Yellow control wires connects to plug #7
2.
Green control wires connects to plug #8
3.
Brown control wires connects to plug #9
4.
White control wires connects to plug #10
7.
Remove back panel on black box. Connect the 12 pin plug to the socket located in the black control box
and tighten plug screws. Route cable through yellow cable guide.
