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.
N O T I C E
Potential Instrument Damage. Delicate internal electronic components can be damaged by static
electricity, resulting in degraded performance or eventual failure.
Refer to the illustrated steps that follow and Table 1 .
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.
