Safety Instructions for Electrical Installation
The electrical connection must only be made by authorised expert personnel ac-
cording to the wiring diagrams.
The notes to the electrical connection in the manual must be observed. Otherwise,
the protection category might be affected.
The safe disconnection of circuits, which are hazardous when touched, is only en-
sured if the connected devices meet the requirements of VDE T.101 (Basic require-
ments for safe disconnection).
The supply lines are to be routed apart from circuits, which are hazardous when
touched, or isolated additionally for a safe disconnection.
An easily accessible isolation device that disconnects all lines must be installed
prior to commissioning of the device to be able to isolate it completely from power
supply.
