Surface mount control units
To fit a surface mount control unit:
1. Apply the surface mount template (supplied at the back of this
handbook) to the selected bulkhead.
2. Mark the centers of the two fixing holes and the cable boss.
3. Drill two 5 mm (
3
/
16
in) diameter holes for the fixing studs.
4. Use a 90 mm (3.55 in) diameter cutter to drill the hole for the
cable boss.
5. Peel the protective sheet from the self-adhesive gasket, then stick
the gasket into position on the rear of the control unit surround.
6. Screw the fixing studs into the control unit.
7. Pass the cables (power, compass, SeaTalk etc.) through the
bulkhead and connect them to the appropriate terminals (as
described later in this chapter).
8. Assemble the control unit to the bulkhead.
9. Secure the control unit with the thumb nuts provided.
Hand-tighten the thumb nuts – do NOT use a wrench.
