Making repairs
Unauthorized opening and improper repairs on the device may result in substantial damage

Safety when working in and on electrical systems
Work in or on electrical systems may only be carried out by authorized persons. The
following safety regulations apply in Germany for the prevention of electric shock and
electrocution:
1. Switch off the system
2. Secure the system to prevent it switching back on
3. Check the system to ensure it is de-energized
4. Ground and short the system
5. Cover or shield adjacent live parts
These safety rules are based on the DIN VDE 0105 standard.
Note
These safety steps must always be taken in the above order before any work on electrical
systems. Once work on an electrical system is finished, cancel the safety steps starting with
the last and finishing with the first.
In accordance with the applicable safety regulations, clearly indicate on an electrical system
that work on it is underway.
Observe the safety regulations applicable in the country of operation.
