Wiring Connections

1. Verify that the power has been shut off at the main breaker.
2. Open the cover to the alternator.
Drive Connections
3.
Connect a two-conductor pressure sensor cable from drive 1 to the
alternator's terminal block labeled SD1 on the right side. The red and
black wire connections are interchangeable. (See Figure 2 below).
Whichever drive unit is connected to the SD1 terminal will be the
primary system first. The drive unit connected to the SD2 terminal will
be the backup system first.
A. If connecting to a SubDrive300, use the supplied two-conductor
pressure sensor cable. Cut the terminals off both ends of the red
and black leads from the existing four-conductor cable. Leave
only the green and white leads linking the pressure shut-off
switch to its connections on the SubDrive300.
B. For all other SubDrives, cut off the quick connect ends and strip
the wire to make a two-conductor cable with stripped leads at
both ends.
4. Repeat step 3 for drive 2, but connect drive 2's pressure sensor cable
to the alternator's terminal block labeled SD2 on the right side.
