Route the connection cables of the components to beconnected through the grommet provided on the under-side of the product on the left.2. Ensure that the grommet is plugged in correctly andthat the cables have been routed correctly.3. Ensure that the grommets envelop the connectioncables tightly and with no visible gaps.4. Use strain reliefs.5. If required, shorten the connection cables.-+NLPE30 mm≤30 mm≤40 mm≤6. Strip the flexible cables as shown in the figure. In doingso, ensure that the insulation on the individual conduct-ors is not damaged.7. Only strip inner conductors just enough to establishstable connections.8. To avoid short circuits resulting from loose individualwires, fit conductor end sleeves on the stripped ends ofthe 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 ifnecessary.11. Plug the plug into the associated PCB slot.– In doing so, observe the wiring diagram in the ap-pendix.7.11.4 Establishing the power supply1. Observe all valid regulations.– The applicable regulations state that the connectionmust be established via an electrical partition with acontact gap of at least 3 mm at each pole.– Power supply cable: Flexible duct2. Make sure that the rated voltage of the mains is 230 V.13. Route a three-core power supply cable that complieswith the relevant standards through the grommet andinto the product.4. Do not interrupt the mains supply with a time switch orprogrammer.5. Isolation should preferably be by a double poleswitched fused spur box having a minimum contactseparation of 3mm on each pole. The fused spur boxshould be readily accessible and preferably adjacent tothe boiler. It should be identified as to its use.
