Components in the installations are exposed to high voltages and currents. Follow these instructions carefully in order to reduce the risk of fire or electric shock.
The following regulations and standards are considered applicable and mandatory to read prior to the installation of electrical equipment:

1. Connection with the main circuit, Wiring should be done bu professional qualified personnel; Wiring should be done after confirmation of complete disconnection of input power supply; Wiring should be done sfter installation of breaker body.
2. International Standards: IEC 60364-7-712 Electrical installations of buildings-Require- ments for special installations or locations-Solar Photovoltaic (PV) power supply systems.
3. Local building regulations.
4. Guidelines for lightning and overvoltage protection.

NOTE

1. It is essential to uphold the limits for voltage and current in all possible operating conditions. Also keep in mind the literature on correct dimensioning and sizing of cabling and components.
2. The installation of these devices may only be performed by certified technical personnel.
3. The wiring schematics of the Firefighter Safety Switch can be found at the end of this manual.
4. All the installation works should be tested in accordance with relevant local legislation at the time of installation.

About Rapid Shutdown

Intended Use of the Rapid Shutdown
The Rapid Shutdown has been especially developed as a safety device for direct current (DC) photovoltaic installations. The DC disconnect switch is used to disconnect the connected strings of the installation in case of an emergency situation. Such an emergency situation could be in case of fire.

Location of the Rapid Shutdown
The Rapid Shutdown needs to be placed as close to the solar panels as possible. Due to its enclosure, the switch is protected against external influences like dust and moisture. The whole set-up is conforms to IP66 which makes it suitable for outdoor usage when needed.

Operation

Normal operation:
The PEFS will automatically switch to the off position, breaking the DC connection between the solar panels and the inverter, after the AC power to the PEFS is interrupted for longer than five seconds. The PEFS will automatically switch to the on position, restoring the DC connection between the solar panels and the inverter, once the AC power to the PEFS is restored longer than five seconds.

Special Operation:
If the temperature inside the PEFS enclosure exceeds the 70℃, the PEFS will automatically switch to OFF to protect the internal components and create a safe situation. When the installation is checked and the PEFS is not affected, the PEFS can be switched ON again by removal and re-applying the AC voltage to the PEFS. The PEFS will also automatically switch to OFF if there is an internal failure. If this occurs please try to reset the PEFS by removal and re-applying the AC voltage to the PEFS.

Installation

Installation Requirements
Open the box, take out PEFS, read this manual, and prepare cross/straight screwdriver.

Installation Steps

1. Pull out the product bottom bracket to both sides.

2. Mount the switch enclosure on the wall.

3. Wire the power AC connection to the terminals.
   Wire Color: According to American standard requirements –L: Black; N: White; G: Green&Yellow
   NOTE
   FB1, FB2 are used to remotely display the on and off states of the switch. When the switch is closed, FB1 is connected to FB2; when the switch is open, FB1 is disconnected from FB2.
   Resistor is selected according to supply voltage, to ensure circuit current less than the rated current of the Indicator light and ＜320mA

4. Wire the string cables to the interface.
   NOTE
   Please follow the marks (1+, 1-, 2+, 2- ) for PV wiring.

5. Note the installation environment (See the schematic on the next page).
   NOTE

   • Do not expose to direct sunlight.
   • Do not expose to rain and snow cover.
   • Do not be in direct contact with (continuous) ingress water. The installation site must have good ventilation condition.
