Damage to seals on the enclosure lids in subfreezing conditions
If you open the enclosure lids when temperatures are below freezing, the enclosure seals can be
damaged. This can lead to moisture entering the inverter.
• Only open the enclosure lids if the ambient temperature is not below 0°C (32°F)
• If a layer of ice has formed on the seal of the lid when temperatures are below freezing,
remove it prior to opening the enclosure lids (e.g. by melting the ice with warm air). Observe
the applicable safety regulations.
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.
Damage to the inverter due to moisture ingress during electrical installation
• Never open the inverter when it is raining or snowing, or the humidity is over 95%.
• For attaching the conduits to the enclosure, only use UL-listed rain-tight conduit fittings or UL-
listed conduit fittings for wet locations complying with UL514B.
• Seal all unused openings tightly.
