3.1 Wiring instructions
3.1.1 Connecting SYN 100-XH-30 to the Grid
1. Remove the two screws on the upper cover of the SYN 100-XH-30 to open the upper cover, and do
not remove the cover inside the machine.
2. Twist the plastic cover printed with "Grid" counterclockwise, remove the five waterproof plugs, and
reserve five holes.
3. Route the five power grid cables (L1/L2/L3/N/PE) through the five holes and connect them to the
power grid input terminals and the ground copper bar. Screw torques for tightening the power grid
terminals and ground terminals are shown in the following table.
4. Finally, fasten the plastic cover clockwise. The wiring method is shown in Figure 3.
Note: PE cables need to be crimped with the O-type
terminal in the accessory bag, as shown in
Figure 2.

2. Use a Phillips screwdriver to loosen the limit switch screw on the power bypass switch.
3. Slide the firmware to one end of the inverter switch.
4. Tighten the screw on the limit switch with a torque of 10.5 in* lbs / 1.2 N*m. Turn on the power bypass switch. The operation instructions
are shown below.
5. Power on the entire system. For details, please refer to section 5.1.
To manually transfer to the bypass mode, please proceed as follows:
1. lf the inverter is connected to a battery, turn the DC SWITCH on the battery to ON.
2. Set the DC SWITCH on the left side of the inverter to ON.
3. Turn on the inverter input breaker of the SYN 100-XH-30.
4. Enable the Backup Box function via inverter settings. For details, please refer to the XH inverter manual.
5. Turn on the grid breaker.
6. If the SYN 100-XH-30 indicator light turns green after completing the preceding steps, it indicates that the SYN 100-XH-30 is functioning
properly.
