6BOILER START-UPELECTRIC ASSEMBLYConnection to the electrical system needs to be done in accordance with the regulations applicable in thecountry where the given boiler is installed, and therefore must be done by qualified electrician (electricalcompany installing the boiler puts a relevant stamp on the guarantee card). Heaters with powers from 4 to24 kW are designed by an alternating current, 3-phase (400V3N~50Hz). 4, 6 and 9 kW versions are alsoavailable in 1-phase (230V1N~50Hz). In case 400V work is essential one should protrude bridge out of L1 L2 L3clamp bar. Boilers AsZN-W, AsD-W and AsDC-W are equipped in TLZ terminal strip. AsB II boiler is equippedin switch disconnector. For this terminal strip one should connect power supply in accordance to L1 L2 L3 N PEdescription. The technical data table (page 7) provides information on the cross-section of the power cord tobe used for boiler connection and the applicable power (A) of the main fuses protecting the boiler.Boiler EKW should be connected to the electric installation by a device enabling full power disconnection. It is alsorequired to use residual current device (in case house installation lacks such).EKW BOILER START-UPA – Connection strip1 – HUW measuring sensor– concerns AsD-W boiler (no. 24)THERMOSTATE0 VOLT !!!654321RELAYS2 – room sensor ELTERM (optional)– clamps (no. 22)3 – „weather” sensor (no. 23)4 – external room temperature controller, recommendedELTERM’s „ThermLine RT” (no. 6)ESC ONOFFSensorsSensorsELTERMBody.
