8.7.4 Low-Voltage Cable Connections at Control Center

8.7.5 Grounding and Bonding


Connect the green ground wire to the supply ground. See bonding lug in Figure 8.
 The Digital Nano/Nano + must also be connected to the pool/spa bonding system with an 8
AWG (6 AWG for Canada) wire. A bonding lug is provided at the bottom, exterior of the control
center.

8.7.6 Connecting to an External Timer or Controller

1. Measure and cut ½" nonmetallic flexible conduit to reach from the power source to the
Digital Nano.
2. Feed the wires from Digital Nano through the conduit.
3. At time clock or external controller relay, connect AC power wiring to the LOAD SIDE or the
same location as the circulation pump wires (pump connected to circuit breaker, time clock
or electronic controller).
4. Connect the ground wire to the ground of the power source.
