the oven is used 

2.1 Electrical 

supply 

50 or 60 Hz. Adequate insulated supply which incorporates earth conductor according to 
EN 61010, Protection IP 20, no humidity protection according to  DIN 40 050. Interference 
suppression Grade N according to VDE 0875, limiting values of the class B, part one. 

A fuse 250V/15A quick is used for oven protection (in ovens with 400V 3N~ power supply 
3 fuses). 

Before current-connection please compare label on the oven and instructions of 
your local current supplier. 

(e.g. in Germany, DIN VDE 0100 with FI - safety device).
