GENERAL NOTICE & SAFETY INSTRUCTIONS
SAVE THESE INSTRUCTIONS -This manual contains important instructions for the BPE Solar building FireFighter Safety
Switch that shall be followed during installation and maintenance of the FireFighter Safety Switch.
General Notice

No part of this publication may be stored, reproduced or copied without prior written permission
from BPE. The material furnished in this document is believed to be accurate and reliable
however, BPE assumes no responsibility for the use of this material. BPE reserves the right to

Important Safety Precautions
Attention! Components in PV 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.
Also keep in mind the literature on correct 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.

Intended use of the Domestic Fireghter
Safety Switch
•The Domestic Firefighter safety Switch 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.
Location of the Domestic Fireghter Safety
Switch
•The switch 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
conforms to lP66 which makes it suitable for outdoor use when needed.
Normal Operation
•AC Supply Cut-Off Shutdown
When the AC power to the BPE-FFSS is interrupted, the BPE-FFSS will automatically switch to
OFF, breaking the DC connection between the solar panels and the inverter. Once the AC
power to the BPE-FFSS is restored, the BPE-FFSS will automatically switch to ON, restoring the
DC connection between the solar panels and the inverter.
Special Operation
•Over Temperature Shutdown
If the temperature inside the BPE-FFSS enclosure exceeds 85°C, the BPE-FFSS 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 to below 75°C, the BPE-FFSS will automatically switch to ON, restoring the
DC connection between the solar panels and the inverter.
•Manual Shutdown
Upon the user activating the red push button switch located in BPE-FFSS enclosure, the BPE-
FFSS performs a Rapid Shutdown, breaking the DC connection between the solar panels and
the inverter.

Step 4 - Testing before use
After the AC Power is connected, Red light is still OFF
Release Emergency Button, Red light ON, within 60 seconds, Switch Indicator turn GREEN to RED.
After 60 seconds, Press Emergency Button, Red light OFF, Switch Indicator turn RED to GREEN.
Step 5 - Connect to PV arrays
Wiring Requirement for EVO2
Note!
Before Connection to PV arrays, Make sure the BPE-FFSS is in “OFF”
status .(Red Indicator OFF, Switch Indicator switch to GREEN)
Warning
All EVO2 connectors must be installed and sealed properly with isolator to maintain
IP66NW rating.
