Installation manual

Installation 1 - 16 CX34/44/54 NavStation
1.8.1 Power supply connections - refer also to section 1.7
The internal voltage regulator will allow the CX34/44/54 to operate normally
within the power supply voltage range from 10 to 32 V DC. The CX34/44/54
is connected to external power (battery or radar supply box) by means of the
supplied power cable, which is approximately 2 meters long and is not extend-
able. After connecting the cable to the power source, push the plug as far as it
will go into the four pin receptacle marked “PWR” on the rear of the cabinet
and turn the plug’s coupling ring clockwise until it makes a click.
1.8.2 Fuse
Warning! A fuse should always be installed to protect the unit.
Using a fuse which is not specified for your equipment can cause it to blow the
instant the CX34/44/54 is switched on or it will not protect the equipment as
intended – see fuse rating in section 1.14 Specifications.
1.8.3 Transducer connection
Most transducers are supplied with a 10 meter cable for connection to the
echosounder unit – CX34/44/54. Push the female plug, as far as it goes, into
the receptacle on CX34 marked “ECHO”, or on CX44/54 marked “ECHO1”
or/and “ECHO2” on the rear of the cabinet and turn the plug’s coupling ring
clockwise until it clicks into locked position
) The unit must be turned off while connecting/disconnecting the transducer
cables.
