Electrical connection:
It is advised that if installing M12IFM12V Models no more than 8 lights should be installed on your
low voltage system and Mains Power Units should be installed (contact BluefinLED for advice).
Only attach the light cable to a waterproof connection or junction box, the cable must have a
watertight connection otherwise your
warranty will be void .
Care should be taken when planning your electrical feeds/cables to the lights so as to ensure voltage
drop between the batteries or power supply is minimised, on 12V systems this is especially important
as the lower system voltage means a high current requirement which in turn means the potential for
more voltage drop in the cable runs & connections.
If the cable gauge & connections are not sufficient for the lighting load attached you may experience
incorrect operation of the lights & intermittent illumination as the supply dips below specification.
Please see the wire gauge guide which is attached to this manual.
For help with calculations always consult with a qualified professional or contact BluefinLED directly.
You will notice an inline moisture guard attached to your cable (Fig 1). If this guard is removed you
warranty will be void
Only attach the light cable to a waterproof connection or junction box, the cable must have a
