NOVA Control Connections
Follow the directions in this section if Model V1305R-DC1 or V1305R-DC1-230 is being installed. These
receivers are for NOVA control systems.
The number of cables is determined by the maximum operating distance, the operating mode (simplex or
duplex) and the receiver configuration (star or daisy-chain). These cables are used to connect the receiver to the
appropriate system components.
Perform either the procedure for a star configuration or a daisy-chain configuration. Only one procedure should
be performed.
Star Configuration
1. Unscrew the domed sealing nut of a cable entry fitting. Refer to Figure 2.
2. Route the cable(s) from the Distribution Line Control (DL) to the receiver.
3. Slip the sealing nut over the cable with the threads facing toward the end of the cable. Position the sealing
nut approximately 10 inches (25 cm) from the end of the cable(s).
4. Insert the end of the cable(s) through the cable entry fitting and thread the nut onto the fitting. Tighten the
sealing nut firmly and secure the cable(s).
