WARNUNG: Electrotechnical work must only be performed by qualified electricians or under their direct supervision and guidance. Failure to comply may result in serious injury or damage to equipment.
3. Produktüberschreitungview
The Eltako DSZ15DE-3x80A is a modular digital current meter designed for direct measurement of active energy. It is suitable for mounting on a DIN-EN 60715 TH35 rail.
- Maximaler Strom: 3 x 80 A
- Standby-Verlust: Only 0.5 W per path
- Montage: DIN-EN 60715 TH35 rail
- Abmessungen: 4 division units (70 mm wide, 58 mm deep)
- Genauigkeitsklasse: B (1%)
- Schnittstelle: S0 interface for pulse output
- Messung: Measures active energy based on current flow. The meter's own consumption of 0.5 W active power per path is not measured or displayed.
- Leiteranschluss: Supports 1, 2, or 3 external conductors with currents up to 80 A.
- Anlaufstrom: 4 mA
- Anzeige: 7-segment LCD, readable for up to two weeks without power supply.
- Leistungsanzeige: A flashing bar on the display indicates power consumption (100 flashes per kWh).
- Tariff Functionality: Can be used as a 2-tariff meter by connecting 230 V to terminals E1/E2.

4. Einrichtung und Installation
The Eltako DSZ15DE-3x80A is designed for easy installation on a standard DIN rail.
- Montage: Securely mount the meter onto a DIN-EN 60715 TH35 rail. The device occupies 4 division units, measuring 70 mm wide and 58 mm deep.
- Verdrahtung: Connect the external conductors (L1, L2, L3) to the appropriate terminals. The meter supports 1, 2, or 3 external conductors with currents up to 80 A.
- Neutralleiteranschluss: An N connector must be available and properly connected for correct operation.
- Tariff Control (Optional): For 2-tariff operation, connect a 230 V supply to the E1/E2 terminals.
Ensure all connections are secure and comply with local electrical codes and safety regulations.
5. Bedienungsanleitung
The meter features a 7-segment LCD display and two control buttons: MODE and SELECT.
5.1. Anzeige und Menünavigation
- Tastenaktivierung: Pressing either the MODE or SELECT button will first activate the display backlight.
- Menüführung: Use the MODE and SELECT buttons, located next to the display, to scroll through the various menu options and display values.
- Available Displays: The meter can display the following information:
- Total active energy per tariff (T1, T2)
- Resettable active energy (RS1 or RS2)
- Instantaneous values for power (P), voltage (U), and current (I) per external conductor (L1, L2, L3)
5.2. Tariff Switching
If configured for 2-tariff operation, the meter will switch between tariffs when 230 V is applied to the E1/E2 terminals.
6. Fehlermeldungen
The meter provides error indications to assist with troubleshooting:
- "false" Error: If an external conductor is missing or the current direction is incorrect, the display will show "false" along with the corresponding external conductor (e.g., "false L1").

8. Wartung
The Eltako DSZ15DE-3x80A digital current meter requires minimal maintenance.
- Halten Sie das Gerät sauber und staubfrei. Verwenden Sie zum Reinigen ein weiches, trockenes Tuch.
- Vermeiden Sie es, das Gerät übermäßiger Feuchtigkeit oder direkter Sonneneinstrahlung auszusetzen.
- Keine Scheuer- oder Lösungsmittel verwenden.
9. Fehlerbehebung
Sollten Sie Probleme mit Ihrem Zähler haben, beachten Sie bitte die folgenden häufigen Probleme und Lösungen:
- Display shows "false" with a conductor label (e.g., "false L1"): This indicates a missing external conductor or incorrect current direction for the specified phase. Check the wiring for the indicated conductor and ensure it is connected correctly and the current flows in the intended direction.
- Anzeige ist leer: Check the main power supply to the circuit being measured. While the display can retain readability for up to two weeks without power, prolonged absence of power will cause it to go blank.
- Falsche Messwerte: Verify that the meter is correctly wired for the number of phases in use (1, 2, or 3 external conductors). Ensure the N connector is properly connected.
If problems persist after attempting these solutions, consult a qualified electrician.
