Route the connection cables of the components to beconnected through the cable duct provided on the un-derside of the product on the left.2. Use strain reliefs.3. Shorten the connection cables as necessary.30 mm max.4. To prevent short circuits if a strand accidentally comesloose, only strip the outer sheathing of flexible lines to amaximum of 30 mm.5. Ensure the inner conductor insulation is not damagedwhen stripping the outer sheathing.6. Only strip inner conductors just enough to establishgood, sound connections.7. To avoid short circuits resulting from loose individualwires, fit conductor end sleeves on the stripped ends ofthe conductors.8. Screw the respective plug to the connection cable.9. Check whether all conductors are sitting mechanicallysecurely in the terminals of the plug. Remedy this ifnecessary.10. Plug the plug into the associated PCB slot; see theconnection diagram in the appendix.5.9.3 Establishing the power supplyCaution.Risk of material damage due to high con-nected voltage.At mains voltages greater than 253 V, elec-tronic components may be damaged.▶ Make sure that the rated voltage of themains is 230 V.1. Make sure that the nominal mains voltage is 230 V.2. Provide one common electricity supply for the boilerand for the corresponding controller:– Power supply: Single-phase, 230 V, 50 Hz– Fuse protection: ≤ 3 A3. Open the electronics box. (→ Page 15)4. Connect the product using a fixed connection and anelectrical partition with a contact opening of at least 3mm (e.g. fuses or power switches).5. Route a three-core mains connection cable that com-plies with the relevant standards through the cable ductand into the product.– Mains connection line: Flexible line6. Carry out the wiring. (→ Page 15)7. Remove the supplied plug from the bracket in the elec-tronics box and screw the plug onto the mains connec-tion cable.8. Close the electronics box.9. Make sure that access to the mains connection is al-ways available and is not covered or blocked.5.9.4 Installing the product in a moistenvironmentDanger!Risk of death from electric shock!If you install the product in a room with highlevels of moisture, e.g. a bathroom, observethe nationally recognised technical standardsfor electrical installations. If you use the fact-ory-installed connection cable, if installed,with an earthed plug, there is a risk of deathfrom electric shock.▶ Never use the factory-installed connectioncable with earthed plug when installing theproduct in a moist environment.▶ Connect the product using a fixed connec-tion and an electrical partition with a con-tact opening of at least 3 mm (e.g. fusesor power switches).▶ Use a flexible line for the mains connec-tion line, which is routed through the cableduct into the product.1. Open the electronics box. (→ Page 15)2. Detach the plug from the PCB slot for the power supply(X1).3. Unscrew the plug of the factory-installed power supplycable, if installed.4. Instead of the factory-installed power supply cable, ifinstalled, use a suitable three-core power supply cablewhich complies with the relevant standards.5. Carry out the wiring. (→ Page 15)6. Close the electronics box.7. Observe the flue-gas connection that is required on aroom-sealed air/flue gas installation. (→ Page 14)5.9.5 Connecting controllers to the electronicsystem1. Install the controller if necessary.2. Open the electronics box. (→ Page 15)3. Carry out the wiring. (→ Page 15)4. Observe the connection diagram in the appendix.Conditions: Connecting a weather compensator or a room temperaturecontroller via eBUS▶ Connect the controller to the eBUS connection.▶ Bridge the 24 V = RT connection (X100 or X106), if thereis not already a bridge.Conditions: Connecting a low-voltage controller (24 V)▶ Remove the bridge and connect the controller to the24 V = RT connection (X100 or X106).Conditions: Connecting 230 volt controller▶ Connect the switched live supply with the terminalmarked RT at X1 (beside the LNPE connections) thenremove the link at X100 (do NOT connect 230 volt toany other terminal than the RT connection).
