4 FAQS
Question: Is the unit protected against voltage spikes?
Answer: Yes, the BMIS incorporates a number of spike protection components
specifically designed to reduce the risk of damaging the unit. The BMIS is also
designed to prevent any spikes being generated by the unit and in turn affecting any
vehicle equipment.
Question: What does the LED indicate?
Answer: The LED indicates the unit is activated and power is available to the vehicle.
A flashing red LED indicates a fault except during the first 5 seconds after turning the
isolation switch on. See section 2.3.1 on page 12.
Question: Can I use the BMIS to shut off the engine?
Answer: Do NOT routinely use the BMIS to shut off the engine except in an emergency
or for routine testing. Use the ignition key as per normal vehicle operation.
It’s recommended to perform an engine shutdown test on a fully charged battery (or
allow a few minutes of engine operation beforehand to recharge the battery as much
as possible). Following these recommendations will minimise the possibility of damage
and/or accelerated wear to vehicle electrical systems.

TECH TIPS
When mounting - ensure torque in 2 stages, criss-cross method with torque wrench
Do
NOT
install star washers between cable lugs and terminals
Ensure cables are straight and do not interfere with the cover/fascia
Flashing LED - check for water or fault connection in wiring harness
Remote switch requires dual pole to operate the BMIS
Make sure the mating Deutsch connector has blanking plugs installed to prevent
potential water ingress
