Wiring instructions
1.Take out the two screws on the upper cover of the machine, open the upper cover, and do not
remove the ugly plate inside the machine.
2.Loosen the plastic cover printed as " Grid " counterclockwise, remove the three waterproof plugs,
and reserve three holes.
3.Route the three power grid cables (L/N/PE) through the three holes and connect them to the power
grid input terminal and the ground copper bar. The screw torque on the power grid terminal is 26.5
in*lbs / 3.0 N*m to 31 in*lbs / 3.5 N*m, and the screw torque on the ground terminal is 13 in*lbs / 1.5
N*m.
4.Finally, fasten the plastic cover clockwise. Wiring is shown as follows:

mounting location, on a wall, stud framing or pole. It is recommended to mount the Backup Interface in a location
protected from direct sunlight.
2.To allow proper heat dissipation, maintain at least a 300mm clearance between the SYN 50-XH-1 and other objects.
3.Position the mounting bracket against the wall/pole and mark the drilling hole locations.
4.Drill the holes and mount the bracket. Verify that the bracket is firmly attached to the mounting surface.
5. Hang SYN 50-XH-1 on the bracket.

2 Connecting SYN 50-XH-1 to the Inverter
When connecting theSYN 50-XH-1 to the XH Inverter, we need to connect AC power cable and communication cable.
1.Loosen the plastic cover printed as "Inverter" counterclockwise, remove the three waterproof plugs, and reserve three holes.
2.Route the cables of the three inverters (L/N/PE) through the three holes, connect the cables to the inverter circuit breaker terminal and the
ground copper bar. The screw torque of the inverter circuit breaker terminal is 17.5 in*lbs / 2 N*m, and the screw torque on the ground
terminal is 13 in*lbs / 1.5 N*m.
3.Finally, fasten the plastic cover clockwise. Wiring is shown as follows:
