Installation
Multiple hazards. Only qualified personnel must conduct the tasks described in this section of the
document.
Connect the sensor to the module
Potential Electrocution Hazard. Always disconnect power to the instrument when making electrical
connections.
Electrocution Hazard. High voltage wiring for the controller is conducted behind the high voltage barrier in the
controller enclosure. The barrier must remain in place except when installing modules, or when a qualified
installation technician is wiring for power, relays or analog and network cards.
Potential Instrument Damage. Delicate internal electronic components can be damaged by static
electricity, resulting in degraded performance or eventual failure.
Make sure that the routing of the sensor cable prevents exposure to high electromagnetic fields (e.g.,
transmitters, motors and switching equipment). Exposure to these fields can cause inaccurate
results.
To install the module and connect the sensor, refer to the illustrated steps that follow and the wiring
table (Table 3 and Table
Be sure to connect all sensor ground/shield wires to the controller enclosure grounding screws.
Note: If the sensor cable is not long enough to reach the controller, an interconnect cable and junction box are
required to extend the distance.
