Danger to life due to applied voltages as a result of automatic reconnection
If the automatic cascade control is activated, it is possible that the voltage is automatically reconnected when
working on the medium-voltage switchgear. Touching live components can result in death or serious injury due to
electric shock.
• For the order option "Cascade control", deactivate the automatic reconnection function at the control device
and the medium-voltage switchgear.
• Deactivate the automatic reconnection function in the superordinate MV Power Station with cascade control.
• Ensure that the control device cannot be accidentally switched on again.
• Wear suitable personal protective equipment for all work on the product.
Hearing impairment due to high-frequency noises of the inverter
The inverter generates high-frequency noises when in operation. This can result in hearing impairment.
• Wear personal protective equipment for all work on the product.
• Wear hearing protection.
Risk of burns due to hot components
Some components of the product can get very hot during operation. Touching these components can cause burns.
• Observe the warnings on all components.
• During operation, do not touch any components marked with such warnings.
• After switching off the product, wait until any hot components have cooled down sufficiently.
• Wear suitable personal protective equipment for all work on the product.
Connect and disconnect the AC voltage of the MV transformer
Only a duly authorized person is allowed to connect and disconnect the AC voltage of the MV transformer.
