- Optional color: White/orange/black; PLC control method or DC 24V manual control are all available.
- One rapid shutdown can control 1,2, or 4 solar modules, Suitable for residential and commercial solar systems.
Installation
Normal installation of PEFS-PL80S-11/PEFS-PL80S-21 will be the connection of
one/two PV panels in series to one RSD unit (typical wiring example below).
Where the combined rating of two panels exceeds the rating of the PEFS-
PL80S-11/PEFS-PL80S-21, or to meet regulatory compliance, a 1-to-1 connection
of the PV module to the Rapid Shutdown can be used. See the diagram on page
3. Connect the array Positive (+) output connector to the RSD Positive (+)
input connector.
Connect the array Negative (-) output connector to the RSD Negative (-) input
connector.
Where a reference has been made above to the use of the PEFS-PL80S-11/PEFS- PL80S-21 as the source of supply of the 24VDC, it can also be considered that power can be supplied to the RSD units by an alternative suitably rated UL Approved 24VDC Class II power supply (AC/DC or DC/DC types). This power supply unit should be used in conjunction with a shutdown initiator that ensures disconnection of the 24VDC supply upon operation, and for the PEFS-PL80S-11 /PEFS-PL80S-21 the appropriate in-line fuse must also be installed in the 24VDC line.As the supply of these parts is outside the scope of Projoy we recommend that the device’s instructions of use are fully understood and the necessary appropriate precautions made when using such parts; and that the correct 24V/OV polarity connections are made as indicated in this installation guide.
MULTIPLE INSTALLATIONS
One RSD PEFS-PL80S-11/PEFS-PL80S-21 will control two solar panels and by
series connection of the Rapid Shutdown, multiple solar panel pairs can be
connected to form a greater capacity system. The diagram below illustrates a
typical example of a Rapid Shutdown protected installation using eight solar
panels and four PEFS-PL80S-11/PEFS-PL80S-21 RSDs. 
Troubleshooting
If it is found that the product cannot be output…
- Please check whether the 24V power supply is normal. After the 24V power supply is restored, the product can output normally.
- Please remove the product first and check the temperature of the product. If it is very hot (over 120°C), do not deal with it at this time. After the temperature of the product is lowered, it will resume normal operation.
- Check the input and output connectors, and whether they are correctly connected and inserted, as shown in the figure below:
Maintenance and Repair
Please check regularly. Specifically, you can press the control box to check whether the output of the whole string is stopped or the output voltage is less than 10V. If the output voltage is greater than 10V, it indicates that there is a fault in the system. Please contact Projoy after-service for handling.
