2 Safety
Danger to life due to high voltages of the PV array
When exposed to light, the PV array generates dangerous DC voltage, which is present in the
DC conductors and the live components of the inverter. Touching the DC conductors or the live
components can lead to lethal electric shocks.
• Disconnect the inverter from voltage sources and make sure it cannot be reconnected
before working on the device.
Risk of burns due to hot enclosure parts
Some parts of the enclosure can get hot during operation.
• During operation, do not touch any parts other than the enclosure lid of the inverter.
Damage to the enclosure seal in subfreezing conditions
If you open the product when temperatures are below freezing, the enclosure seals can be
damaged. Moisture can penetrate the product then.
• Only open the product if the ambient temperature is not below 0°C (32°F).
• If a layer of ice has formed on the enclosure seal when temperatures are below freezing,
remove it prior to opening the product (e.g. by melting the ice with warm air). Observe the
applicable safety regulations.
Damage due to sand, dust and moisture ingress
Sand, dust and moisture penetration can damage the product and impair its functionality.
• Only open the inverter if the humidity is within the thresholds and the environment is free of
sand and dust.
• Do not open the inverter during a dust storm or precipitation.
• Close tightly all enclosure openings.
• Only use listed rain-tight or liquid-tight conduit fittings to attach the conduits to the product.
Damage to the inverter or product due to electrostatic discharge
Touching electronic components can cause damage to or destroy the inverter or the product
through electrostatic discharge.
• Ground yourself before touching any component.
