Connecting electrical power to the radio link
•
Screw on the plug connections of the connecting cables to protect against water penetration
(fig. 4, page 4).
•
When laying the cables, make sure:
– they are not kinked or twisted
– they do not rub on edges
– they are not laid in sharp-edged ducts without protection (fig. 3, page 4).
•
Protect every through-hole made in the bodywork against water penetration, e.g. by using a
cable with a sealant and by spraying the cable and the cable sleeve with sealant.
I
NOTE
Only start sealing through-holes when you have completed all installation work on the
camera and have laid the required cable lengths.
7.2 Connecting electrical power to the transmitter module
A
NOTICE!
Make sure the polarity is correct.
VT150DIG requires a few seconds to initiate the digital wireless connection. To keep this start-up
time short, you should connect the transmitter module to an active +12 V voltage supply. If no
continuous operating voltage is available, you can connect the transmitter module to the reversing
light.
Connecting the transmitter module to a continuous operating voltage
➤ Connect the red cable of the transmitter module (fig. 6 7, page 5) to an active positive cable,
e.g. terminal 15.
➤ Connect the black cable of the transmitter module (fig. 6 8, page 5) to earth (bodywork).
➤ Connect the green cable of the transmitter module (fig. 6 6, page 5) to the reversing light.
Connecting the transmitter module to the reversing light (no continuous operating
voltage)

NOTE
•
These connection options only work with cameras not equipped with a motor
shutter.
•
On some vehicles, the reversing light only works when the ignition is switched on.
In this case, you must switch on the ignition in order to identify the positive and earth
wires.
➤ Connect the red cable of the transmitter module (fig. 6 7, page 5) to the positive wire (+) of
the reversing light.
➤ Connect the black cable of the transmitter module (fig. 6 8, page 5) to the earth wire (–) of
the reversing light or to earth (bodywork).
