Danger to life from electric shocks due to live voltage and risk of injury from short-circuit currents
High voltages are present inside the Sunny Island. When the enclosure lid is removed, live components can be touched
which can result in death or serious injury due to electric shock. Short-circuit currents in the battery can cause heat
build-up and electric arcs. Burns or eye injuries due to flashes may result.
• When carrying out any work on the electrical installation, wear suitable personal protective equipment.
• Turn off or disconnect the following devices from voltage sources in the given order:
– Sunny Island
– In the distribution board the circuit breakers of the Sunny Island inverters and of the control and measurement
voltages
– Load-break switch of the battery
• Ensure that the system cannot be reconnected.
• Open the enclosure lid of the Sunny Island and ensure that no voltage is present.
• Ground and short-circuit the AC conductors outside the Sunny Island inverter.
• Cover or isolate any adjacent live components.
Danger to life from electric shock due to damaged Sunny Island
Operating a damaged Sunny Island can lead to hazardous situations that can result in death or serious injuries due to
electric shock.
• Only operate the Sunny Island when it is technically faultless and in an operationally safe state.
• Regularly check the Sunny Island for visible damage.
• Make sure that all external safety equipment is freely accessible at all times.
• Make sure that all safety equipment is in good working order.
Risk of crushing injuries due to movable generator parts
Moving parts in the generator can crush or sever body parts. A generator can be started automatically by the
Sunny Island.
• Only operate the generator with the safety equipment.
• Install, maintain, and operate the generator according to the manufacturer's specifications.
