C. POWER WIRING
1. Provide a conduit stub for the AC power.
2. The gate operator requires a 115 VAC 20 AMP single phase circuit.
3. Be sure to pull a ground wire in the conduit for the connection to the gate operator.
Important: Do not rely on metallic conduit for earth ground.
D. LOOP DETECTORS
• The gate operator has a shelf that can support loop detector electronics. Power for the loop
detector can come from the auxiliary 115 VAC plugs in the gate operator or from the 24 VAC
provided by the gate operator.
• Conduit provisions should be made for the “loop” wire entrance to the loop detector.
• The shelf space provided is approximately 4” x 10” x 18” high.
NOTE: Shelf space on systems without the Power Fail Option is about 10" x 10" x18".
E. TELEPHONE CONNECTION
• Provisions should be made for a conduit entrance into the gate operator for the telephone line.
• A single twisted pair wire 18 AWG to 24 AWG, will be connected from the telephone company
termination block through the conduit to J9 on the control board. Polarity is not important.
NOTE: Do not run telephone and AC power wires in the same conduit
F. OTHER CONNECTIONS
Provisions should be made for conduit entrance into the gate operator for external activating
devices such as key switches, telephone entry systems, etc.
