10 DSM300 Installation Manual
1.3 Selecting Sounder Module Mounting Location
The DSM300 is waterproof to IPX-7 is and is designed to be mounted either above
or below deck.
Mount the DSM300 where it is:
• protected from physical damage and excessive vibration
• protected from prolonged exposure to rain, salt spray and direct sunlight
• well ventilated
• as close to the transducer as possible
Do not locate the DSM300:
• in the engine compartment
• on the main console
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 con-
nections 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 chapter.)
•
Magnetic compass: Mount the unit at least 3 ft (1 m) away from a magnetic
compass.
•
Cable runs: The unit must be located near a DC power source. The power
cable supplied is 10 ft (3 m).
•
Environment: Good ventilation is required to prevent the unit from over-
heating.
CAUTION: Do Not Remove the Transducer Cable
Removing the transducer cable from the DSM300 while power is
turned on can cause sparks. As with any electronic device, be sure
the sounder module is mounted where it is well ventilated and
free from gasoline fumes.
