CONDUIT CONNECTIONS
Be sure power to the operator is disconnected.
1. Use a liquid tight fi tting (1/2" trade size) with sealing washer to connect to sensors. The sensors are provided with 36" long leads.
We recommend the use of a liquid tight junction box near each sensor to make the connection to the sensor leads. Use rigid or fl exible
liquid tight conduit (depending on local codes) from junction boxes to operator.
IMPORTANT: Use a minimum size 20 ga. copper wire for connection between the sensors and the operator.
2. Connect the sensor wires to the operator (refer to Wiring Connections, page 6).
3. Connect power to the operator.
4. Align the photoelectric sensors so the green LED on the sending sensor and the Yellow LED on the receiving sensor glow steadily.
