ELECTRICAL SAFETY HAZARDS
WARNING! An electric shock can be fatal. High danger due to grid voltage and voltage from the
turbine that is operational.
➢
Ensure that the turbine is not operational before carrying out any connection work.
➢
Only an authorized electrician is permitted to connect this equipment to the public grid.
The SETUR-M turbine generates a 3-phase alternating current (AC) which is then rectified to direct
current (DC), then inverted into a pure sine wave single-phase 220-240 V (110-120 V USA model)
alternating current (AC).
WARNING! Incorrect operation or poorly executed work can cause serious injury or damage.
Commissioning of the turbine and inverter may only be carried out by trained personnel in
accordance with the technical regulations.
Caution should always be used when connecting the SETUR turbine to the electric system. Please read
and follow the user's manual, installation and operating instructions provided by the inverter
manufacturer.
IMPORTANT! Ensure that you have followed the cable-sizing requirements to ensure that the
correct size of transmission cable has been selected. If a cable of insufficient cross-sectional
area is used, heat may build up in the cables causing a potential fire hazard. Using cables of
insufficient cross-sectional area may also reduce the power transmission efficiency of the turbine.
Always use the largest gauge wires that are practical and affordable. Local, state and/or national
electrical codes take precedence over these general recommendations.
Never run the SETUR turbine 'off-load' with the output cables not connected to anything.
WARNING! Adhere to proper grounding techniques as established by your National Electrical
Code. Your SETUR turbine must be installed in accordance with this manual, local and national
codes, rules and regulations. Incorrect installation may void your warranty.
WARNING! NEVER PERFORM ANY ELECTRICAL WORK WHILE
STANDING IN WATER OR BEING EXPOSED TO WATER! WEARING WET
GLOVES OR CLOTHES IS FORBIDDEN!
Please use common sense when installing and operating your turbine!
