• Cable runs: The unit must be located near a DC power source. The
power cable supplied is 5 ft (1.5 m), but a longer cable can be used if
desired. Refer to
Section 2.4 .
The maximum length of cable between the fishfinder and the transducer
unit should not normally exceed 25 ft (8 m).
• Environment: Good ventilation is required to prevent overheating.
WARNING:
Removing the transducer cable from the DS400/500X while power is
turned on can cause sparks. As with any electronic device, be sure the
fishfinder is mounted where it is well ventilated and free from gasoline
fumes.
2.4 Cable Runs
Consider the following before installing the system cables:
• You will need to attach the power and transducer cables to the rear of the
unit.
• All cables should be adequately secured, protected from physical dam-
age and exposure to heat.
• Avoid running cables through bilges or doorways, or close to moving or
hot objects.
• Avoid sharp bends.
• Where a cable passes through an exposed bulkhead or deckhead, use a
watertight feed-through.
• Secure cables in place using tie-wraps or lacing twine. Coil any extra
cable and tie it out of the way.
You will need to run the following cables:
• Power/NMEA cable , supplied with the unit. This 5 ft (1.5 m) cable has
a connector plug at one end for connecting to the fishfinder, and 3 wires at
the other end for connecting the power supply. The power cable may be
extended by up to 60 ft (20 m) using a wire gauge of AWG 12 or greater.
The DS400/500X is intended for use on the boat’s DC power systems
rated from 10-18 Volts DC (13.8V nominal).
• Transducer cable , supplied with the transducer. This 25 ft (8 m) cable
has a connector plug at one end for the display unit.
