Installation (Cont.)
Fitting guidelines
The cooker is manufactured to work with three-phase alternating current
(400V 3N~50Hz). The voltage rating of the cooker heating elements is 220-
240V. Adapting the cooker to operate with one-phase current is possible
by appropriate bridging in the connection box according to the connection
diagram (Fig. 16). The connection diagram is also found on the cover of
the connection box. Remember that the connection wire should match the
connection type and the power rating of the cooker.
The connection cable must be secured in a strain-relief clamp.
CAUTION!
Remember to connect the safety circuit to the connection box terminal
marked with
