Battery Safety Information - SMA SUNNY ISLAND 4.4M Operating Manual

2 Safety
Risk of crushing injuries due to moving PV array parts
A generator can be started automatically by the Sunny Island. Moving parts in the PV array can crush or sever body
parts.
• Operate the generator only with the specified safety equipment.
• Carry out all work on the generator in accordance with the manufacturer's specifications.
Risk of burns due to short-circuit currents on the disconnected inverter
The capacitors in the DC input area of the inverter store energy. After the battery is isolated from the inverter, battery
voltage is still temporarily present at the DC terminal. A short circuit at the DC terminal of the inverter can lead to
burns and may damage the inverter.
• Wait 15 minutes before performing any work at the DC terminal or on the DC cables. This allows the capacitors
to discharge.
Risk of burns due to hot enclosure parts
Some parts of the enclosure can get hot during operation.
• Mount the inverter in such a way that it cannot be touched inadvertently during operation.
Damage to the product due to sand, dust or moisture penetration
Sand, dust or moisture penetration can damage the inverter or impair its functionality.
• Do not open the inverter during a sandstorm, precipitation or when humidity exceeds 95%.
• Only perform maintenance work on the inverter when the environment is dry and free of dust.
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.
Damage to seals on the enclosure lids in subfreezing conditions
If you open the enclosure lid when temperatures are below freezing, the enclosure lid seal could be damaged. This
can lead to moisture entering the inverter.
• Only open the enclosure lid if the ambient temperature is not below -5°C
• 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 lid (e.g. by melting the ice with warm air). Observe the applicable safety regulations.
