DANGER!
Danger to life due to high voltages in the charge controller.
• Disconnect the PV array using a disconnection unit and secure it against accidental
reactivation.
• Disconnect the miniature 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.
NOTICE!
Electrostatic discharges may damage the charge controller.
• Ground yourself before touching a component inside the charge controller.
NOTICE!
Overvoltage can destroy the system.
• Use an external overvoltage protector in areas with an increased risk of
thunderstorms and lightning.
