WARNING!
The unit must always be powered by either a suitable
UL 60950/CSA
Certified power supply which is
isolated from line voltage by double insulation, or an appropriately rated UL listed/CSA Certified Class 2
transformer. Failure to follow the above can result in serious injury or loss of life.
The sensor consists of two basic parts, the base and the cover (
Fig. 1). The cover incorporates the electronics
with the sensing elements.
(1) Mark four holes as shown in Fig. 2.
(2) Drill holes of appropriate diameter for wall plugs.
(3) Remove the cover from the base and
(4) Attach base with screws of appropriate diameter.
(5) Fasten the base to a junction box or other support.
The base has a number of openings to allow for mounting to various junction boxes.
(6) Feed the power and signal wires through the rectangular opening in the base.
(7) Connect the wires to the terminal connector located in the base, as indicated in Fig. 3.
See also Wiring Connections in Fig. 5.
(8) If RS-485 sensors are being tied into a control device, insert a two-position jumper into J6 on the sensor board
that is wired farthest from the controller. This enables the RS-485 termination resistor.
(9) Align the two side tabs of the cover with the base and snap the cover onto the base.
(10) Verify cover is securely attached to base by pulling on the top and bottom of the cover as shown in Fig. 4.
To remove the cover, grasp it along the recesses and pull it away from the base (
Fig. 4).
Alternatively
, place a screwdriver into the slots indicated in Fig. 4 and twist.
