Installation steps
1.Determine SYN 50-XH-1 mounting location, on a wall, stud framing or pole.It is recommended to mount it in a location proected 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.
Note: The above dimensions are in "mm".

3.1.1 Connecting SYN 50-XH-1 to the Grid
1.Take out the two screws on the front cover of the SYN 50-XH-1, open the front cover, and do not
remove the safety 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 as shown in Figure 3:
Note： PE cables needs to be pressed into the O-type terminal in the accessory bag, as shown in Figure 2.

3.1.2 Connecting SYN 50-XH-1 to the Inverter
When connecting the SYN 50-XH-1 to the XH Inverter, we need to connect AC power cable and communication cable.
1)Connecting the AC 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:
