SINUMERIK 840D Configuring Manual NCU (PHD) – 03.06 Edition
2.1.2 Safe isolation to EN 61800–5–1
The complete system includes user interfaces (UIs) and interfaces for servicing,
startup and maintenance.
UIs are all the interfaces that are freely accessible to the machine operator wi-
thout the need for tools or aids. These user interfaces are designed with safe
isolation to EN 61800–5–1.
!
Danger
The interfaces for servicing, start-up and maintenance purposes are provided
without safe isolation.
If necessary, these interfaces can be isolated safely using a supplementary
adapter (insulation voltage 230 V AC). Although these adapters are not included
in the Siemens scope of delivery, you can buy these parts from your local
dealer, who will be happy to advise you.
!
Danger
Safe isolation can only be ensured if the system configuration specified below
is strictly adhered to. When mounting additional components (e.g., S7-300 FM,
IP) with a UI, please make sure that the UI has basic insulation for at least
230 V AC.
