Replacing the Micro SD Card
DANGER
Danger to life due to electric shock when live components or cables are touched
High voltages are present in the conductive components or cables of the product. Touching live parts and cables
results in death or lethal injuries due to electric shock.
• Do not touch non-insulated parts or cables.
• Disconnect the product from voltage sources and ensure it cannot be reconnected before working on the
device.
• After disconnection, wait 15 minutes until the capacitors have discharged.
• Observe all safety information on components associated with the product.
• Wear suitable personal protective equipment for all work on the product.
NOTICE
Damage to the inverter due to electrostatic discharge
Touching electronic components can cause damage to or destroy the inverter through electrostatic discharge.
• Ground yourself before touching any component.
