2. Use strain reliefs.
3. If required, shorten the connection cables.
30 mm ≤
4. Strip the flexible line as shown in the figure. In doing so,
ensure that the insulation on the individual conductors
is not damaged.
5. Only strip inner conductors just enough to establish
good, sound connections.
6. To avoid short circuits resulting from loose individual
wires, fit conductor end sleeves on the stripped ends of
the conductors.
7. Screw the respective plug to the connection cable.
8. Check whether all conductors are inserted mechanic-
ally securely in the plug terminals. Remedy this if ne-
cessary.
9. Plug the plug into the associated PCB slot; see the wir-
ing diagram in the appendix.

1. Observe all valid regulations.
–
The applicable regulations state that the connection
must be established via an electrical partition with a
contact gap of at least 3 mm at each pole.
2. Make sure that the rated voltage of the mains is 230 V.
3. Provide one common power supply for the boiler and
for the corresponding control:
–
Power supply: Single-phase, 230 V, 50 Hz
–
Cover plate:

8. Screw the supplied plug to a three-core power supply
cable that complies with the relevant standards.
9. Connect the plug for the power supply cable.
10. Make sure that access to the power supply is always
available and is not covered or blocked.
