trics” section.
NOTE.
In devices with integrated electric heating element,
the electric heating element is connected for 9 kW
(6 kW) in the factory. At contactor Q, it is possible
to select 6 kW (4 kW) = 2 phase operation.
Disconnect Q5/6 for this. Or 3 kW (2 kW) = 1
phase operation. Disconnect Q5/6 and Q5/4 for this.
The values in brackets are for the 6 kW heating
element. Disconnected cables must be furnished
with screw terminals. Only the phases cited above
may be disconnected (safety temperature limiter).
POWER CONNECTION
