SAVE THESE INSTRUCTIONS -This manual contains important instructions for ZJBENY Solar building Fire Fighter Safety Switch that shall be followed during installation and
maintenance of the Fire Fighter Safety Switch BFS-S1, BFS-S2, BFS-S3.
No part of this publication may be stored, reproduced or copied without prior written permission from ZJBENY The material furnished in this document is believed to be accurate
and reliable however, ZJBENY assumes no responsibility for the use of this material ZJBENY reserves the right to make changes to the information contained at any time without
prior notice. All products and company names mentioned in this manual are trademarks or registered trademarks of their respective holders. The information contained herein is

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.
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.
The installation of these devices may only be performed by certified technical personnel.
All the installation works should be tested in accordance with relevant local legislation at the time of installation.
The Domestic Firefighter safety Switch(BFS-S) 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.
The BFS-S 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 lP66 which makes it suitable for outdoor usage when needed.
AC Supply Cut-Off Shutdown
When the AC power to the BFS-S is interrupted, the BFS-S will automatically switch to OFF, breaking the DC connection between the solar panels and the inverter.
Once the AC power to the BFS-S is restored, the BFS-S will automatically switch to ON, restoring the DC connection between the solar panels and the inverter.
Over Temperature Shutdown
If the temperature inside the BFS-S enclosure exceeds 85°C, the BFS-S will automatically switch to OFF, breaking the DC connection between the solar panels
and the inverter, to protect the internal components and create a safe situation. Once the temperature drop back to below 75°C, the BFS-S will automatically
switch to ON, restoring the DC connection between the solar panels and the inverter.
Manual Shutdown
Upon the user operating the red push button switch located in BFS-S enclosure, the BFS-S performs a Rapid Shutdown, breaking the DC connection between
the solar panels and the inverter. panels and the inverter.
