General Instructions for On-Board Wiring
•
Ensure good electrical contacts and interference suppression of all parts of the
electrical system, e.g., alternator, ignition system, etc., also check for influences of
vibration and corrosion.
•
Connecting wires are to be placed as far as possible from other wires carrying large
currents, antenna lines, etc., as well as control wires, control cables, etc. Keep
power lines at least 15 cm from the compass.
•
Use self-extinguishing wires designed for at least 600 V (complying with MIL-W-
5086C or MIL-W-16878D). Use only stranded wire to avoid broken wires caused by
vibration.
•
The suggested cross sections should be kept.
•
Ground loops must be avoided.
•
The wires are soldered to the connector DA-15S. Isolate the joints by shrinking
sleeves or rubber tubes.
•
The transceivers are only protected against wrong polarity, if a suitable fuse is
installed. We recommend a semi time lag acting fuse 2.5 A or an automatic circuit
breaker 2.5 Amp.
•
If no suitable fuse is installed the units can be damaged and no guarantee claim will
be accepted.
•
Assemble connector according Fig. 3-6, do not crush any wires.
•
Before plugging the connector to the unit check carefully the wiring, particularly the
(+) and (-) wiring.
•
After plugging secure the connector against loosening by pushing the sliding lock
retainer.
•
For easy on-board wiring (only pin and socket connectors) we have prefabricated
cable assemblies on stock.
