• While PSFS-PL80P-11 or PEFS-PL80P-21 are used without PEFS-PLC-CN, be sure that this photovoltaic rapid shutdown equipment (PVRSE) does not perform all of the functions of a complete photovoltaic rapid shutdown system (PVRSS). This PVRSE must be installed with other equipment to form a complete PVRSS that meets the requirements of NEC (NFPA 70) section 690.12 for controlled conductors outside the array. Other equipment installed in or on this PV system may adversely affect the operation of the PVRSS. It is the responsibility of the installer to ensure that the completed PV system meets the rapid shut down functional requirements. This equipment must be installed according to the manufacturer’s installation instructions.
• While PSFS-PL80P-11 or PEFS-PL80P-21 are used with PEFS-PLC-CN, be sure that this photovoltaic rapid shutdown system (PVRSS) incorporates one or more pieces of equipment that exercise the rapid shutdown control of PV system conductors required by section 690.12 of the NEC (NFPA 70). other equipment installed in or on this  PV system may adversely affect the operation of this PVRSS. it is the responsibility of the installer to ensure that the completed PV system meets the applicable rapid shut down functional requirements. this equipment must be installed according to the manufacturer’s installation instructions.

CAUTION

• The PSFS-PL80P-11 or PEFS-PL80P-21 will become hot during operation. Please do not touch the surface during or shortly after operation.
• Risk of damage due to improper modifications.
• All electrical installations must be done in accordance with the National Wiring Rules of Standard and local code.

2.2 Explanations of Symbols

4.3 Installation of PEFS-PL80P-11/21

WARNING

While PEFS-PL80P-11/21 are used without PEFS-PLC-CN, be sure that this photovoltaic rapid shutdown equipment (PVRSE) does not perform all of the functions of a  complete photovoltaic rapid shutdown system (PVRSS). This PVRSE must be installed with other equipment to form a complete PVRSS that meets the requirements of  NEC (NFPA 70) section 690.12 for controlled conductors outside the array. Other equipment installed in or on this PV system may adversely affect the operation of the  PVRSS. It is the responsibility of the installer to ensure that the completed PV system meets the rapid shutdown functional requirements. This equipment must be installed according to the manufacturer’s installation instructions.

1. Fix the rapid shutdown device (PEFS-PL80P-11/21) on the frame of solar module.
   

2. Connect the input of the rapid shutdown device to the solar module.
   

3. Connect the outputs of all the rapid shutdown devices one after another.
   

4. While PEFS-PL80P-21 are used without PEFS-PLC-CN, connect each string of the rapid shutdown devices to the solar inverter.

4.4 Installation of PEFS-PC

WARNING

While PEFS-PL80P-21 are used with PEFS-PLC-CN, be sure that this photovoltaic rapid shutdown system (PVRSS) incorporates one or more pieces of equipment that exercise the rapid shutdown control of PV system conductors required by section 690.12 of the NEC (NFPA 70). other equipment installed in or on this PV system may adversely affect the operation of this PVRSS. it is the responsibility of the installer to ensure that the completed PV system meets the applicable rapid shutdown functional requirements. this equipment must be installed according to the manufacturer’s installation instructions.
Installers should determine the installation location of the rapid shutdown controller according to local regulations.

1. Push out the bracket of the rapid shutdown controller. Fix the rapid shutdown controller (PEFS-PLC-CN) on the wall.
   

2. Plug each string of rapid shutdown devices to the rapid shutdown controller. Then plug each output cable to the solar inverter.
   

3. Multiple control boxes can be connected in series and can be controlled by a single master control box.
   

4. Put the warning label in the PV system as required in section 690.56(C) of NEC (NFPA70).
   

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

| On| Off
---|---|---
Power (Red)| The rapid shutdown controller is powered on and sends signals to the rapid shutdown devices in each string. The status of the lights is shown below:| The rapid shutdown controller is powered off or stops sending signals to the rapid shutdown devices in each string.

Table 4.1 Light Status

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

System Test and Troubleshooting

5.1 System test
5.1.1 Function test
Please do the function test regularly.

1. Push the button of the 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.

5.1.2 Maintain test
When the PEFS-PLC-CN stops working, the PEFS-PL80P-11 will have a continuous 0.9 V output and the PEFS-PL80P-21 will have a continuous 1.75 V output.

1. Push the button and stop the PEFS-PLC-CN.
2. Separate the DC cable and rapid shutdown controller. Test the voltage of each DC cable.

System Voltage = 0.9 V Quantities of PEFS-PL80P-11 or
System Voltage = 1.75 V Quantities of PEFS-PL80P-21| System Work Normally
---|---
System Voltage < 0.9 V Quantities of PEFS-PL80P-11 or
System Voltage < 1.75 V Quantities of PEFS-PL80P-21| System Work Abnormally

5.2 Troubleshooting

The status light is always off.
PVRSS doesn’t work.| 1)  Check if the button of the 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 range;
4)  Contact Projoy.

The DC voltage of the inverter is 0V.
PVRSS doesn’t work.| 1) Test the voltage of the DC cable. If the voltage of the DC cable is zero, check the connection of the DC cable.
2)  If the voltage of the DC cable is normal as described in §5.1.2, there is something wrong with the DC input of the inverter. Contact the supplier of the inverter.
3) Contact Projoy.
The status light is on.
The DC voltage of the inverter is 0V.
PVRSS doesn’t work.| 1)  Check if the button of the 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 range;
4)  Contact Projoy.
The status light is on.PVRSS works well.
DC voltage of the inverter is
abnormal (§5.1.2).| 1) Test the output voltage of each rapid shutdown device. If the output voltage is not 0.9V or 1.8V. Replace the rapid shutdown device.
2)  Contact Projoy.
