Schaudt EBL 119 House Charger wiring diagram

The EBL 119 is an integrated motorhome power unit containing a mains charger, distribution circuits and battery switching. This catalog entry deliberately covers only its mains-to-house-battery charging function: AC L/N/PE and house charging positive/negative. Starter-battery maintenance charging, alternator coupling, refrigerator branches, solar input and the control-panel harness are real functions described in the manual, pages 7–10, but are not connected or simulated by this symbol.

This limited model avoids turning controlled battery connections into a permanent parallel bus. It is not a replacement for the vehicle's complete EBL wiring plan. The overvoltage-protection feature belongs specifically to the OVP version, not every unit carrying an EBL 119 label.

The technical data, pages 9–10, states 230 V AC ±10%, 47–63 Hz, 1.9 A input, and up to 18 A house-battery charging current. The 1.9 A figure is mains current; it is not 12 V consumption. Actual charging current falls with charge stage, battery acceptance and thermal conditions.

The reviewed profiles cover six-cell gel and AGM batteries of at least 80 Ah. Gel uses a 14.4 V absorption stage and AGM 14.7 V, followed by 13.7 V float; the listed absorption durations are 16 and 4 hours respectively. Select the correct profile with the system isolated as the manual instructs. No lithium profile is documented by this revision.

The catalog's `out-pos` and `out-neg` refer to the house-battery charging connection. The complete installation diagram, page 15, shows 50 A protection at each battery positive for the full integrated system, which also carries distribution and alternator currents. That 50 A figure must not be read as 50 A charger output, nor transferred blindly to an isolated 18 A charging-only design. Use the full EBL and vehicle wiring instructions when connecting a real unit.

AC protective earth must be connected as part of the mains installation. Keep the mains and DC routes distinct and have the mains circuit and protection checked by a qualified installer. The terminal envelopes here are the documented 1.9 A input and 18 A charging limits, not the ratings of every EBL internal bus or connector.

Verify battery polarity, chemistry selection, fuse positions and the compatible control panel before energizing. Keep ventilation open: page 6 describes automatic current reduction when the unit overheats. If house charging fails, check incoming mains and reduce competing loads before concluding that the charger has failed. A starter-battery or alternator fault must be diagnosed using the omitted full-system paths, not this charging-only model. For long storage, follow the battery charging and cutoff sequence; operating the cutoff can release the heater's frost valve and drain water.
