SINUMERIK 810D Equipment Manual Configuration CCU (PHC) – 03/2006 Edition

2.1.2 Safe isolation to EN 61800-5-1

The complete system includes end user interfaces (UIs) and interfaces for

servicing, commissioning and maintenance.

UIs are all the interfaces that are freely accessible to the machine operator

without the need for tools or aids. These user interfaces are designed with safe

isolation to EN 61800-5-1.

Danger

The interfaces for servicing, commissioning 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). These adapters are not included in the

Siemens scope of delivery. You can buy these parts from your local dealer who

will help you to make the proper choice.

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 an end user interface, please make sure that the end user interface

has a basic insulation for at least 230 V AC.
