9.6.1 Power supply connections
The internal voltage regulator will allow the EQXX to operate normally over the
power supply voltage range from 10 to 32 V dc. Connections between the EQXX
and the external power supply are accomplished by means of the supplied power
cable, which is approximately 1.5 meters long.
After connecting the cable to the power source, push the plug as far as it will go
into the two pin receptacle marked “PWR” on the rear of the cabinet and turn the
plug’s coupling ring clockwise until it clicks into locked position.
9.6.2 Fuse
Warning! Using a fuse which is not specified for your equipment can cause it to
blow the instant the EQXX has been switched on or it will not protect the
equipment in the event of trouble. Refer to 9.11 Specifications.
9.6.3 Transducer connection
