2 Safety
Risk of burns from hot surfaces
The surface of the inverter can get very hot. Touching the surface can result in burns.
• Mount the inverter in such a way that it cannot be touched inadvertently.
• Do not touch hot surfaces.
• Wait 30 minutes for the surface to cool sufficiently.
• Observe the safety messages on the inverter.
Risk of fire
• To reduce the risk of fire, connect only to a circuit provided with 50 A maximum branch-
circuit overcurrent protection in accordance with the National Electrical Code
NFPA 70).
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 -5°C (23°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 product if the humidity is within the thresholds and the environment is free of
sand and dust.
• Do not open the product 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.
