2) CRR 220
3) Voltage stabiliser (24V DC / ≥ 20A) e.g. Bosch 1 687 022 873
The picture is a schematic representation of the rear
panel.
Connect the CRR 220, as shown, to a voltage stabiliser
using suitable connecting cables. The CRR 120 can also
be connected as an option.
!
Never operate the CRR 220 without the earth cable
connected (PE). The 24 V (-) connection must be
connected to the protective earth conductor (PE). At
the output of the CRR 220, the length of the con-
necting cables must not exceed 2m (Ø 2,5 mm²).
The below picture (Fig. 6) shows the front of the unit.
