INSTALLATION

UM344-2

b)The cable shield(s) may be grounded at a Network Junction Box or Wiring Panel provided that the cable shields are connected to either a terminal or the Box or Panel frame, and the terminal or frame is grounded.

The power supply (+) and (-) connections must be floated and the cable shield at the transmitter must not be connected.

ŸMulti-Drop Network

If the Primary Master's power supply output is isolated from ground, the Network may be floated. The cable shield should be connected only to one point: the Primary Master's negative supply output.

ŸSensor Cable

a)Shielded sensor cable should be used (remote mounted sensor) to minimize the effects of electric noise. The sensor wires should be twisted to minimize magnetic induced noise.

b)On a remote mounted thermocouple, if the thermocouple measuring junction is grounded to its sheath (which is also grounded), connect the sensor cable shield to ground as close as practical to the measuring junction.

c)On a remote mounted thermocouple, if a thermocouple measuring junction is ungrounded, ground the cable shield and the negative thermocouple wire to a common point as close as practical to the measuring junction.

d)Do not connect the cable shield to ground at the Transmitter's terminal compartment if the cable shield is grounded at the sensor assembly.
