of system installation are complete and have been
performed correctly.
1. Sensors are pointing down and junction boxes are
securely mounted.
2. All cable shields are properly grounded.
3. All junction box covers are tightly installed.
4. Explosion-proof conduit seals have been installed
at all junction box entries (if conduit is being
used).
5. Sensor to controller wiring is correct.
6. Power wiring to the controller is installed and
power source is operational.

STARTUP PROCEDURE
1. Output loads that are normally actuated by the
system should be secured (remove power from all
output devices) to prevent undesired activation.
2. Check all external wiring for proper connection.
Be sure that the sensor has been wired properly.
3. Before installing the controller in the mounting
rack, inspect it to verify that it has not been physi-
cally damaged in shipment. Check the jumper
plugs and rocker switches on the controller for
proper programming, then slide the controller fully
into the mounting rack.
4. Apply power to the system.
