CABLE LAYOUT
Plan the cable layout for both the power and transducer cables. All cables should be
adequately secured, protected from physical damage and excessive vibration. Route cables
through conduits for additional protection.
DO NOT CUT AND RE-JOIN TRANSDUCER CABLE.
If it is necessary to run a transducer cable
through a bulkhead, a 20mm drill bit or hole saw should be used to accommodate the plug.
Always check the other side of the bulkhead before drilling to ensure it is clear and safe
avoiding damage to other items. Use a rubber grommet to protect the cable from chaffing
around the area of the hole.
DO NOT COIL SURPLUS TRANSDUCER CABLE.
Coiling up cable can affect the output. Lay
excess cable out over its own length and tie together.

CABLE LAYOUT and ELECTRICAL CONNECTIONS
ELECTRICAL CONNECTIONS
AC VOLTAGE:
The AC version is supplied with a fixed cable and plug. The plug can be
removed if wiring direct onto an AC power supply panel.
NOTE:
the AC power input must be protected by a fuse or circuit breaker rated to 5 amps
(250v).
NOTE: Removing the AC cable from the internal power supply unit will void the warranty.
DC VOLTAGE:
NOTE:
the power supply must be a permanent supply to enable the system
to operate continuously and when the batteries are isolated.
Connect the DC (+) cable directly to the battery source, either to the (+) terminal or live
terminal of the battery switch. A permanently live (+) BUS Bar can also be used. The negative
(-) cable connects to any common 0 volt terminal or BUS Bar.
NOTE:
the positive (+) cable must be protected by a fuse or circuit breaker rated to 10 amps.
DO NOT REVERSE THE POLARITY ON CONNECTION! The polarity must be checked.
Brown (+) positive 24v DC
Blue (-) negative 0v
