Chapter 10-8 CE33 Installation and service
10.6.1 Power supply connections
The internal voltage regulator will allow the CE33 to operate normally within
the power supply voltage range from 10 to 32 V DC. The CE33 is connected to
external power (battery) by means of the supplied power/NMEA cable. Cable
length is approximately 2 meters.
After connecting the cable to the power source, push the plug as far as it will
go into the nine pin receptacle marked “PWR” on the rear of the cabinet and
turn the plug’s coupling ring clockwise until it makes a click.
10.6.2 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 CE33 is switched on or it will not protect the equipment as intended
– see fuse rating in section 10.12 Specifications.
10.6.3 Transducer connection
Most transducers are supplied with a 10 meter cable for connection to the

pling ring clockwise until it clicks into locked position
The CE33 must be turned off while connecting/disconnecting the trans-
ducer cables.
