ECTIVE IR 140 7
These instructions assume that you have mounted an auxiliary battery
(preferably a deep cycle battery) in your vehicle.
1. Disconnect the negative terminal of the starter battery
2. Pick a position for the isolating relay that is easily accessible, as close as
possible to the starter battery and that does not result in cables running near
exhausts.
3. Remove the lower mounting plate from the isolating relay and use it to mark
the positions of the four holes to be drilled. Drill the holes using a 3.5mm drill bit.
4. Secure the two blind holes of the base with the short 4mm screws.
5. Take the red, 6m long cable. Begin from the center of the mounting plate and
run the cable along the inner guard to the positive terminal of the starter battery.
Be sure to keep the cable away from any moving parts. Cut the cable to length.
6. Repeat this step to connect the positive terminal of the auxiliary battery.
7. Strip the un-terminated ends of both cables back 15mm. Fit the copper lugs
and crimp in place, making sure the connection is secure. Alternatively, you can
solder the cable to the lug.
8. Slide the heat shrink over the lug and cable and secure it with a hairdryer or
flame.
9. Attach the insulated ring terminal to the black wire on the isolating relay. This
is an earth wire and it is important that it has a secure and clean (bare metal)
contact. If possible, select a nearby bolt or screw that is earthed to the body.
10. Attach both red cables to the isolating relay and tighten the retaining nuts.
The cable from the starter battery goes to the stud on the isolating relay with the
printed red dot. The cable from the auxiliary battery goes to the other stud. You
will have to cut the notched sections in the isolating relay housing where you
require the cable
to exit.
11. Mount the isolating relay on the bottom plate and fix it with the two 4mm
longer screws.
12. Secure the black earth lead on the isolating relay to the selected earth point.
13. Fit the positive (red) battery terminal and the negative (black) battery
