Important safety precautions
Attention! 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:
• International Standards: IEC 60364-7-712 Electrical installations of buildings – Requirements for special installations or
locations – Solar Photovoltaic (PV) power supply systems
• MIS3002: Microgeneration Installation Standard - requirements for contractors undertaking the supply, design,
installation, set to work commissioning and handover of solar photovoltaic (PV) microgeneration systems
• Local building regulations
• Guidelines for lightning and overvoltage protection
Note!
• It is essential to uphold the limits for voltage and current in all possible operating conditions (see page 11; 'Technical
Data'). Also keep in mind the literature on correct dimensioning and sizing of cabling and components.
• The installation of these devices may only be performed by certified technical personnel.
• The wiring schematics of the Domestic Firefighter safety Switch can be founde at the end of this manual.
• All the installation works should be tested in accordance with relevant local legislation at the time of installation.
Intended use of the Domestic Firefighter safety Switch
The Domestic Firefighter safety Switch (DFS) 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 Domestic Firefighter Safety Switch
The DFS 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 IP65 which makes it suitable for
outdoor usage when needed.
NOTE: The switch enclosure may not be installed in direct sunlight or be in direct contact with (continuous) ingress
water.
Normal operation:
The DFS will automatically switch to the off position, breaking the DC connection between the solar panels and the
inverter, after the AC power to the DFS is interrupted for longer than five seconds. The DFS will automatically switch to
the on position, restoring the DC connection between the solar panels and the inverter, once the AC power to the DFS is
restored longer than five seconds.
Special Operation:
If the temperature inside the DFS enclosure exceeds the 100°C, the DFS will automatically switch to OFF to protect the
internal components and create a safe situation. When the installation is checked and the DFS is not affected, the DFS
can be switched ON again by removal and re-applying the AC voltage to the DFS. The DFS will also automatically switch
to OFF if there is an internal failure. If this occurs please try to reset the DFS by removal and re-applying the AC voltage
to the DFS.
