SAFETY MEASURES
Installers are responsible for the safe and effective installation and operation of the system and for adhering to all applicable local and
national standards and regulations. All relevant local codes and regulations must be referred to and observed.
WARNING ELECTRICAL SHOCK
• Solar panels generate direct current (DC). Once current is flowing, breaking a connection (e.g., disconnecting
two panels) can cause an electrical arc. Unlike low voltage AC wiring, DC arcs are not self-extinguishing; they are
potentially lethal burn and fire hazards, capable of high temperatures that can destroy contacts and connectors:
• Isolate the system and remove/open the inverter AC fuse/circuit breaker from the grid before carrying out any
maintenance or repair work.
• Follow inverter manufacturer’s installation, handling and operating instructions.
• High-voltage components need sufficient time to discharge. Wait for the time specified by the manufacturer
before commencing work.
• Do not use a panel which is broken or damaged. If the panel front glass is broken or laminate back sheet is
damaged, it can expose personnel to hazardous voltages.
SAFETY IN THE WORKING AREA
Installation of REC solar panels may involve working on rooftops or raised platforms. Ensure all local regulations regarding working at
heights and fall protection are followed. Before beginning work on an installation, ensure all working surfaces are structurally sound and
capable of bearing the weight of employees and required equipment.
PREVENTING CURRENT GENERATION
To prevent the panels automatically generating current (electricity) when exposed to light, shield the system with a non-transparent cover
during installation, maintenance or repair work.
SPECIFIC HAZARDS OF DC ELECTRICITY
The voltage produced by a single panel, and panels connected in series (voltages added together), or in parallel (currents added together)
can be dangerous. Although the fully insulated plug contacts on the panel’s output cables provide touch-safe protection, the following points
must be observed during handling to avoid the risk of sparking, fire hazards, burns and lethal electric shocks:
• Exercise extreme caution when wiring panels and look out for damaged or dirty cables etc,
• Never insert metallic or other conductive objects into plugs or sockets,
• Ensure that all electrical connections are completely dry before assembly,
• Keep all materials, tools, and working conditions dry and tidy,
• Use appropriate safety equipment e.g., non-slip footwear, insulated gloves and insulated tools,
• Solar panels produce current when exposed to sunlight. Do not connect the system to the inverter during solar exposure.
