1. Push out the bracket of the rapid shutdown controller. Fix the rapid shutdown controller (TSOL-RSDM-CQ) on the wall.
   Figure 4.6&4.7 Fixing the Rapid Shutdown Controller
   

2. Connect the AC cable to the to the distribution box or another power source. The definition of the port is shown below:

   • (Brown/Black): Live

   • (Blue/White): Neutral

   • (Yellow-Green/Green): Ground
     Figure 4.8 AC Cable
     WARNING

   • Make sure each cable is connected to the right port.

   • To prevent electrical hazards, make sure the power source of rapid shutdown controller is turned to “OFF” position.
       WARNING

   • Make sure each cable is connected to the right port.

   • To prevent electrical hazards, make sure the power source of rapid shutdown controller is turned to “OFF” position.

3. Make the DC cable of each string.
   
   Figure 4.9&4.110&4.11&4.12 Make the DC cable

4. Plug each string of rapid shutdown devices to the rapid shutdown controller. Then plug each output cable to the solar inverter.
   Figure 4.13 Connect the DC cable

5. Put the warning label in the PV system as required in the section 690.56(C) of NEC (NFPA70).Figure 4.14 Warning Label of PVRSS

Start the PVRSS system
Turn on the power source of rapid shutdown controller. The rapid shutdown control system will start to work. The status of lights is shown as below:

Table 4.1 Light Status

| On| Off
---|---|---
Power (Red)| Rapid shutdown controller is powered on and send signals to the rapid shutdown devices in each string.| Rapid shutdown controller is powered off or stop sending signals to the rapid shutdown devices in each string.

Firefighters can push the button to cut off all the solar modules while in the emergency. After the emergency, users can rotate the button and the solar module will work again.

System Test and Troubleshooting

System test
Function test
Please do the function test regularly.

1. Push the button of rapid shutdown controller. The status of light will be off. Check the solar inverter. The DC current will be cut off and the DC voltage will be lower than 30V in 30 seconds.
2. Rotate the button of rapid shutdown controller. The status of light will be on. The solar will start to work again.

Maintain test
When the TSOL-RSDM-CQ stops working, the TSOL-RSDM-DS will have a continuous 0.9 V output and the TSOL-RSDM-DD will have a continuous 1.75 V output.

1. Push the button and stop the TSOL-RSDM-CQ.
2. Separate the DC cable and rapid shutdown controller. Test the voltage of each DC cable.

Table 5.1 System test

System Voltage = 0.9 V * Quantities of TSOL-RSDM-DS or System Voltage = 1.75 V

• Quantities of TSOL-RSDM-DD	System Work Normally

  System Voltage < 0.9 V * Quantities of TSOL-RSDM-DS or System Voltage < 1.75 V

• Quantities of TSOL-RSDM-DD| System Work Abnormally

Troubleshooting

Table 5.2 Troubleshooting

1. Check if the button of controller is turned to off;
2. Check if the AC power supply is normal;
3. Check if the AC voltage is over the operating voltage rang;
4. Contact TSUN.

Status light is on.
DC voltage of inverter is 0V.
PVRSS doesn’t work.| Test the voltage of DC cable. If the voltage of DC cable is zero, check the connection of DC cable.
If the voltage of DC cable is normal as described in §5.1.2, there is something wrong in the DC input of inverter. Contact the supplier of inverter.
Contact TSUN.
Status light is on.

DC voltage of inverter is normal.

PVRSS doesn’t work.

1. Replace a new rapid shutdown controller. 2)Contact TSUN.

Status light is on.|

1. Test the output voltage of each rapid shutdown device. If the

PVRSS work well. DC voltage of inverter is abnormal (§5.1.2).| output voltage is not 0.9V or 1.8V. Replace the rapid shutdown device. Contact TSUN.
