Installation Manual SCxxxHE-20-IA-IEN111210 11
Electric shock resulting from a failure to comply with safety requirements
Failure to follow this manual, the general instructions or safety instructions may lead to severe injury
due to 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.
Electrostatic discharge can damage electronic components
Electrostatic discharge can destroy component parts.
• During work on the inverter and handling of the components, observe the ESD protection
regulations and wear protective gloves.
• Discharge electrostatic charges through contact with unvarnished, grounded enclosure parts
(e.g., on the PE connection of 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.
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.
Penetrating moisture can damage the inverter.
• Do not open the inverter when it is raining or in case of humidity > 95%.
Electrostatic discharge can destroy components.
• During work on the inverter and handling of the components, observe the ESD protection
regulations and wear protective gloves.
• Discharge electrostatic charges through contact with unvarnished, grounded enclosure parts
(e.g., on the PE connection of the doors). Only then it is safe to touch any electronic components.
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. It is imperative that the escape
route is freely accessible 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.
