DANGER

There is a risk of fatal electric

shocks when working on electrical
components of the system

–

Work may be performed only by a qualified
electrician.

–

Applicable standards and regulations must
be observed.

7.1 Voltage supply for the heating sys-

tem

–

A separate power circuit must be provided in the
Aufstellraum for the heating system.

–

Connection 230 V AC / 50 Hz C13 A

–

Specification for the mains connection cable (e.g.
in case of replacement): cable SIHF-J 3x1.5 mm²
