Installation

WARNING: SHOCK HAZARD

Before wiring the Sun Tie XR, ensure the main 120/240 volt breaker in the main utility breaker box is switched off. Switch this breaker on only after all wiring is completed as instructed in the procedures.

To wire the main utility panel to the Sun Tie XR:

1.Run conduit from the main utility breaker panel to the lower section of the Sun Tie XR. Run the two HOT wires (L1 and L2) and ground through the conduit and into the Sun Tie XR’s lower section. Metal conduit is highly recommended.

2.Install or use existing double-pole 15-amp circuit breaker (or two single-pole 15-amp breakers, ganged) in the main utility breaker panel.

3.Connect the L1 HOT wire (black) from the 15-amp, double-pole breaker installed in the main breaker panel, to the breaker labeled L1 in the Sun Tie XR. Refer to Figure 2-11.

4.Connect the L2 HOT wire (red) from the remaining 15-amp, double- pole breaker installed in the main breaker panel, to the breaker labeled L2 in the Sun Tie XR.

5.Connect the ground wire (green or bare copper) from the ground bar in the main breaker panel, to the ground bar in the lower section of the Sun Tie XR.

6.Ensure all connections are correctly wired and properly torqued.

7.Torque wires according to the following values.
