Revision D
2.2.2 Satellite Electronics (only provided with systems that have several instruments)
1. Transmitter(s) Power/COM: A DeviceNet 5711 cable is used for RS485 communication
and power for all transmitters. The color code for this cable is: RS-485 communications:
white (A), blue (B) and shield (SH); power: 24Vdc, red (+), and black (

).
2. Power: Power connection wires should be at least 18 AWG. Connect power terminals to a
dedicated 120 or 240 VAC, single phase, 15-amp circuit. A power switch is provided near
the input power terminals.
2.2.3 Distribution Box (see Figure 6) – For distributing RS485 communication and 24VDC
1. Connect the provided DeviceNet 5711 cable from the main processor unit to screw
terminal, JP1. The color code for this cable is: RS-485 communications: white (A), blue
(B) and shield (SH); power: 24Vdc, red (+), and black (

).
2. Install ½" conduit between the distribution box and probes. Intek recommends 6 feet of
liquid-tight conduit between conduit and probes to minimize stress at the connector.
3. An adapter is provided which allows attachment of ½" flexible conduit to the connector.
4. Connect the probes to the distribution enclosure using the manufacturer supplied
DeviceNet 5711 cable to the screw terminals labeled JP3 to JP6 (refer to Figure 6).
5. For systems with multiple distribution boxes, screw terminal JP2 will be used to connect
to the JP1 screw terminal on the next distribution box in the series.
6. If no additional distribution boxes are used, ensure the outgoing termination resistor (JP7
or JP8) is enabled.
