SMA Solar Technology AG 2 Safety
Operating Manual SCxxxHE-20-BE-BEN111210 13
Electric shock resulting from a failure to comply with safety requirements
Failure to follow this manual, the general instructions or the safety instructions may lead to severe
injury or death from electric shock.
• Only perform work as described in this manual.
• Observe all safety instructions.
• Establish all electrical connections according to the circuit diagram.
• Safely store the documentation within the immediate area of the inverter. It must be accessible
to service and maintenance personnel at all times.
If the key remains in the door lock, the inverter can be opened by unauthorized persons.
• Remove the key from the door locks and from the key switch.
• Keep the keys in a safe place.
Electrostatic discharge can damage electronic components
Electrostatic discharge can damage or destroy electronic component parts.
• When working on the inverter or handling components, observe the ESD safety regulations and
wear protective gloves.
• Discharge the electrostatic charge through contact with unvarnished, grounded enclosure parts
(e.g. the protective conductor connection on the doors). Only then is it safe to touch any
electronic components.
Burn Hazard
Some components, such as fuses, can become hot during operation.
• Wear safety gloves when working on the inverter.
Inverter Damage
Tampering with the device may result in plant damage.
• Do not operate the inverter while the door is open.
Penetrating moisture can damage the inverter.
• Do not open the inverter when it is raining or the humidity is greater than 95%.
Warning signs must be easily readable at all times and must be replaced in the event of damage.
Hazard due to blocked escape route
Opening of the doors of 2 opposing inverters blocks the escape route. An escape route must be
available at all times. Make sure the minimum passage width of the route meets local standards. In
Germany, the minimum passage width is 500 mm.
• Only the door of one inverter may be open at any given time.
