Electrical connections of the device
12 V direct current system
Connect the red wire of the power cord to the plus terminal of the battery and the
black or blue wire to the minus terminal. A 15 A main fuse must be installed near
the battery on the red plus wire of the power cord. See picture.
24 V direct current system
If the device is to receive power from a 24 V system, always connect a charg-
ing voltage reducer and a 12 V battery before connecting the device. Without the
battery the voltage reducer will not be enough on its own as it cannot generate the
large amount of current the glow plug requires. After the 12 V battery, the connec -
tion is the same as in a 12 V system.

Jointing
A jointing should only be made in long
power cords, if necessary, in which case
the cord must be replaced with a thicker
one. The jointing should be less than 1
meter from the device.

Checking the connection
The device consumes most power when it is started up (glowing). At this point volt-
age losses are also at their highest. During the glowing phase, the voltage must be
at least 11,5 V measured at the quick coupling. See picture. If the voltage is lower
than this, the device may not start.
The unit should be connected to a battery used for purposes other than
starting the engine, if possible.
