Safety Information

This section contains safety information that must be observed at all times when working on or with
the product.
To prevent personal injury and property damage and to ensure long-term operation of the product,
read this section carefully and observe all safety information at all times.
Danger to life due to high voltages of the PV array
When exposed to sunlight, 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.
• Prior to performing any work on the inverter, always disconnect the inverter from voltage
sources on the AC and DC sides as described in the inverter manual. When doing so, note
that even if the DC load-break is switched off, there will be dangerous direct voltage
present in the DC conductors of the inverter.
Damage to seals on the enclosure lids in subfreezing conditions
If you open one of the enclosure lids when temperatures are below freezing, the enclosure lid
seal could be damaged. This can lead to moisture entering the inverter.
• Do not open the inverter unless the ambient temperatures is at least 0°C (32°F) and
conditions are frost-free.
• If a layer of ice has formed in sub-zero conditions, remove it prior to opening the enclosure
lids of the inverter (e.g. by melting the ice with warm air). Observe the applicable safety
regulations.
