Safe Isolation To En 61800-5-1 - Siemens SINUMERIK 810DE powerline Equipment Manual

2 Connection Conditions
2.1 Supplementary electrical conditions
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.
End user
UIs are all the interfaces that are freely accessible to the machine operator
interfaces (UI) without the need for tools or aids. These user interfaces are designed with safe
isolation to EN 61800-5-1.
Interfaces for
servicing,
commissioning
and maintenance
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.

CCU module
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.
