Plug the wiring harness connector into the
interconnection circuit board’s P23 connector.
Connect lead ES3 to TB1 terminal 3 and connect
lead ES4 to TB1 terminal 4. See Figure 5. If
access to the interconnection circuit board is
difficult, remove the two controller panel top
screws and center bottom screw and then loosen
the bottom screws on each side to swing the rear
controller panel down.
2.7
Swing the rear controller panel up and replace the
screws, if previously removed.
Replace the
controller cover and hardware.
Tighten all
controller screws.
3.
Mount the 14-relay dry contact box.
3.1
Determine a mounting location for the 14-relay dry
contact box (A-293983). See Figure 6. Consider
the supplied wiring harness length when choosing
a mounting location. If the most suitable location
requires a longer harness, fabricate a new
harness using the supplied harness as a guide.
Note:
The supplied wiring harness (293982)
allows a maximum distance of 1.5 m (5 ft.)
between the 14-relay dry contact box and
the controller connection terminal strip.
Choose one of the following mounting locations
for the 14-relay dry contact box, in order of
acceptability:
D
The junction box top; the size of the controller
and the size of the junction box limit the
mounting location.
D
The generator skid top; the clearance and
housing options limit the mounting location.
D
An area as near to the generator set controller
as practical.
3.2
Remove the four cover screws (X-6216-1) and lift
the box cover (256880) to access the internal
components.
3.3
Mount the 14-relay dry contact box in a location
selected
using
customer-supplied
mounting
hardware. The 14-relay dry contact box has four
7.5 mm (0.297 in.) diameter holes in the bottom
surface for mounting.
3.4
Wire the 14-relay dry contact box to the controller
connection terminal strip using the cable wiring
harness (293982). See Figure 7. Connect the
controller connection terminal strip terminals 2
(ground) and 42A (battery voltage) to the 14-relay
dry contact box terminal strip to provide an
electrical source to operate the K1--K14 relays.
