5.1 Safety
Danger!
High voltages are present and dangerous
• Disconnect the PV array using a disconnection unit and secure it against
accidental reactivation.
• Disconnect the circuit breaker and ensure that it cannot be reconnected.
• Ensure that no voltage is present in the system.
Warning:
Risk of injury due to electric shock
。
If all cables with different voltages are routed in parallel, damaged cable
insulations may lead to a short circuit.
• Route all cables separately if possible.
Warning:
Over voltage can destroy the system.
• Use an external over voltage protector in areas with an increased risk of
lightning.
