• The charge controller must be easy to remove from the mounting location at any
time.
• The ambient temperature should be between -20 °C and +60 °C to guarantee optimal
operation.
• Do not expose the charge controller to direct sunlight to avoid power losses due to
overheating.

5.1 Safety
Danger!
Danger to life due to high voltage in the solar charge controller.
• 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.
Warning:
Over voltage can destroy the system.
• Use an external over voltage protector in areas with an increased risk of
thunderstorm and lightning.
