2.1 Safety Instructions
• Do not disconnect PEFS-PL while the PVRSS is working. There is possibility of dying due to electrical
shock and high voltage.
• To prevent risk of electric shock during installation and maintenance, please make sure that PEFS-PLC-CN
or any other control unit, such as the DC switch of inverter, are turned off.
•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.
•The installation, service, recycling and disposal of the PVRSS must be performed by qualified personnel
only in compliance with national and local standards and regulations.
•Any unauthorized actions including modification of product functionality of any form may cause lethal
hazard to the operator, third parties, the units or their property. Projoy is not responsible for the loss and
these warranty claims.
•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.
