M Series Data Radio – User Manual

Power Supply Requirements

The M Series radio modem is designed and calibrated to operate from

a filtered 13.8Vdc regulated supply, but will operate from a 10-16Vdc

range. See the User Manual for more details on power supply

requirements.

Caution: There is NO internal replaceable fuse and therefore

an external fuse MUST be fitted as shown in diagram below

(MR450: 3 amp slo-blow fuse, EB450: 5 amp fast-blow fuse,

EH450 Controller 1 amp slo-blow fuse).

The radio is designed to self protect, and will blow the external fuse if

the voltage exceeds 16Vdc, or if reverse polarity is applied.

The radio modem can also be damaged if there is any potential

difference between the chassis-ground, RS232 signal ground, power (-

) input, or antenna coaxial shield. Before connecting any wiring,

ensure all components are earthed to a common ground point (please

pay particular attention to 24V PLC power systems where converters

are used).

Connect the antenna and RS 232 plugs BEFORE applying power to

the unit.

Lastly, before inserting the power plug, please

re-check that the polarity and voltage on the

power plug is correct using a multimeter.

Failure to use an external fuse will result in

damage to the radio which will void the warranty.
