Rules for working on electrical systems
The combi oven must be electrically connected in conformity with all applicable regulations and gener‐

It is necessary to ensure that all electrical precautions, guards, and devices (mechanical and electri‐

after any servicing, maintenance, or repair work. Moreover, this must be verified and documented by
means of measurements if required by applicable regulations.
Before being worked on, the unit must always be de-energized and locked and tagged out. In addition,
it is necessary to double-check that it has actually been de-energized properly.
After it has been established that the unit is properly de-energized, it is necessary to wait at least

In order to ensure operating and functional safety, all electrical connections must be checked, and all
required and mandatory electrical tests for placement into operation and regular operation must be
carried out.
