6. Strip the flexible cables as shown in the figure. In doing
so, ensure that the insulation on the individual conduct-
ors is not damaged.
7. Only strip inner conductors just enough to establish
stable connections.
8. To avoid short circuits resulting from loose individual
wires, fit conductor end sleeves on the stripped ends of
the conductors.
9. Screw the respective plug to the connection cable.
10. Check whether all conductors are inserted mechanic-
ally securely in the terminals of the plug. Remedy this if
necessary.
11. Plug the plug into the associated PCB slot.

In doing so, observe the wiring diagram in the ap-
pendix.
7.10.4 Establishing the power supply
1. Observe all valid regulations.
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
–
Fuse protection:
≤
3 A
4. Do not interrupt the mains supply with a time switch or
programmer.
5. Connect the product using a fixed connection and an
electrical partition with a contact gap of at least 3 mm
(e.g. fuses or power switches).
6. Isolation should preferably be by a double pole
switched fused spur box having a minimum contact
separation of 3 mm on each pole. The fused spur box
should be readily accessible and preferably adjacent to
the boiler. It should be identified as to its use.

8. Screw the supplied plug (2) to a three-core power sup-
ply cable that complies with the relevant standards.
9. Observe the routing of the power supply cable (1) in the
electronics box in order to guarantee that there is no
strain.
10. Insert the plug into the bush in the electronics box.
11. Make sure that access to the power supply is always
available and is not covered or blocked.
