3.1.2.1 AC power cable connection:
3.1.2.2 Communication cable connection:
1.Twist the plastic cover printed with "Inverter" counterclockwise;
remove the five waterproof plugs, and reserve five holes.
2.Route the five cables of the inverter (L1/L2/L3/N/PE) through
the five holes, connect the cables to the inverter breaker terminals
(L1/L2/L3/N) and the ground copper bar. Screw torques for
tightening the inverter breaker terminals and ground terminals are
shown in the following table.
3.Finally, fasten the plastic cover clockwise. The wiring method is
shown below:
1.Twist the plastic cover printed with "COM" on the machine
Counterclockwise; remove the waterproof plug, and reserve one
hole.
2.Route the two communication cables (A/B) (the twisted pair cable
are recommend) and the two BOX EN cables (EN+/EN-) through the
hole, connect them to the CN8 terminals on the control board,
connect the other end of the cables to the COM terminals of the
inverter, and tighten the screws. The following table lists the
corresponding terminal pins. The wiring method is shown as follows:
Connecting the communication cables to the XH Inverter
Connecting the AC cables to the XH Inverter
3.1.3 Connecting SYN 50-XH-30 to the load
1.Twist the plastic cover printed with "Load" counterclockwise,
remove the five waterproof plugs, and reserve three holes.
2.Route the five load cables (L1/L2/L3/N/PE) through the five holes,
connect them to the load circuit breaker terminals(L1/L2/L3/N) and
ground copper bar. Screw torques for tightening the load breaker
terminals and ground terminals.
3.Finally, fasten the plastic cover clockwise. The wiring method is
shown on the right:

2.Turn off the DC switch of the inverter.
3.Turn off the DC switch of the battery.
4.Wait for a while and all the indicators of the inverter, the battery, and the SYN 50-XH-30 will go off, indicating that the system is powered
off completely.
6.
Transfer to the bypass mode manually
When SYN 50-XH-30 s is faulty, it cannot transfer to the bypass mode automatically. In order to ensure uninterrupted power supply to loads，
the bypass mode can be initiated manually.
1.Shut down the entire system. For details, please refer to section 5.2.
2.Use a Phillips screwdriver to loosen the limit switch screws on the power bypass switch.
3.Slide the firmware to one end of the inverter switch.
4.Tighten the screws on the limit switch with a torque of 10.5 in* lbs / 1.2 N*m. Turn on the power bypass switch. The operation instruction
s are shown below.
5.Power on the entire system. For details, please refer to section 5.1.
The operation is as follows:
1.Turn on the DC switch of the battery. For details, please refer to the battery manual.
2.Turn on the DC switch of the inverter. For details, please refer to the XH inverter manual.
3.Turn on the inverter input breaker of the SYN 50-XH-30, and observe whether the inverter and battery indicators are displayed. If yes,
move on to the next step. If the indicators are not displayed, it means that there is no mains supply. You need to press and hold the
POWER button of the battery for a long period to wake up the battery. Please refer to the battery installation manual.
4.If the backup box is connected, please enable the Backup Box via inverter settings. For details, please refer to the Chapter 9.3.3 in the
manual of Inverter.
5.Turn on the grid switch.
