General Wiring Procedures
4. Remove the cable conduit plugs only from the hole(s) that will be used.
As shown in the installation layout drawing
868695 , lay one conduit
for the signal cables (and DC power input, if applicable), and a second
conduit for the AC power input.
5. Pull each cable through the correct conduit fitting and into the
enclosure. Leave approximately 150 mm (six inches) for strain relief.
Secure the conduit, making sure it is completely sealed.
6. Connect the input power and the signal wires as follows. Reference the
installation wiring drawing
868577 .
a. Remove the plug-in screw-terminal connector from the board
connector. The connector should be tightly seated. To remove the
connector, brace the board with your hand, being careful not to
touch any of the circuits or components.
b. Use a 1/8-inch screwdriver to loosen the screws on the plug-in
connector.
c. Insert the wires and make connections as shown in the installation
wiring drawing.
d. Tighten the screws in the connector to secure the wires and plug
the screw-terminal connector back into the corresponding onboard
connector.
e. The optional temperature compensation board uses a spring
terminal block connector. For each wire to be connected, use a flat
screwdriver to push and hold the appropriate tab down. Insert the
wire, and then release the tab to secure the wire.
7. When the detector wiring is complete, replace and secure the detector
housing cover.
