Chapter 2: Installation 7
2.3 Selecting the Equipment Location
Mounting Location
The DS400/500 is waterproof to IPX7 is and designed to be mounted either
above or below deck. The unit should be protected from physical damage and
excessive vibration.
CAUTION:
Mount the DS400/500 in a protected area away from prolonged
exposure to rain, salt spray, and direct sunlight, but well ventilated.
When planning the installation, the following should be considered to ensure
reliable and trouble free operation:
• Access: There must be sufficient space below the unit to enable cable
connections to the panel connectors, avoiding tight bends in the cable.
• Interference: The selected location should be far enough away from
devices that may cause interference, such as motors, generators, and
radio transmitter/receivers (see the EMC guidelines earlier in this sec-
tion).
• Magnetic compass: Mount the unit at least 3 ft (1m) away from a mag-
netic compass.
• 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). If you need to use a longer
cable, refer to Section 2.4.
• Environment: Good ventilation is required to prevent the unit from
overheating.
WARNING:
Removal of the transducer cable from the DS400/500 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.
