Mounting and Installation Instructions
The radio should be mounted in a clean and dry location, protected from water, excessive dust,
corrosive fumes, extremes of temperature and direct sunlight. In high power or high temperature
applications, please allow sufficient passive or active ventilation. To avoid moisture ingress
mount the radio with the connectors facing downwards.
Please choose an enclosure that is suitable for the size of the radio : Dimensions are 100 x 34 x
165mm (4.0 x 1.4 x 6.5 inches).The radio is rated for use in ambient (operating) environments
from -40
O
C to +70
O
C.
Connecting Antennas and RF Feeders
The RF antenna system should be installed in accordance with the
manufacturers notes. Antenna gain must be considered when setting Transmit Power. Refer to
Compliance notices at the end of this document and in the use manual for more information.
The RF connectors on this product are TNC Type female connectors. Always use good quality
low loss feeder cable, selected according to the length of the cable run. Ensure all external
connections are waterproofed.
Power Supply Requirements
Tx: Nominal 13.8 Volts DC @ 800 mA (Max 1A)
Rx: Nominal 13.8 Volts DC @ 150 mA
Rated Operating Voltage 10 - 30 Volts DC
Power Supply Protection and Precautions
The J Series Radio is supplied with the a mating DC power connector: Phoenix Contact Part Number
1777989. The DC Power connector should be installed with the locking screws done up tightly. Cable
must be #22 AWG or larger, 70o C min. temperature rating. CSA maximum current rating: 2.5A.
The J Series Ethernet radio modem will operate from a 10 to 30 volt (filtered) DC supply. The radio is
designed to self protect from permanent damage if the voltage exceeds 30V dc or if reverse polarity
is applied. The replaceable internal fuse has a rating 3 Amp.
The current requirement is typically 180mA @ 13.8 V DC in receive mode, and will vary in transmit
mode according to RF output power level & duty cycle.
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,ethernet and RS 232 plugs BEFORE applying power to the unit. Lastly, be-
fore inserting the power plug, please re-check that the polarity and voltage on the DC power plug
is correct using a multimeter.
