4. Maklumat Keselamatan

AMARAN: Installation and maintenance should only be performed by qualified personnel to prevent electric shock or damage to the device. Always disconnect power before working on electrical circuits.

• Ensure the power supply is completely disconnected before installation or wiring.
• Sahkan bahawa voltage and current ratings of the meter match your application requirements.
• Jangan kendalikan peranti dalam keadaan basah atau damp syarat.
• Avoid exposing the meter to direct sunlight or extreme temperatures.
• Gunakan peralatan pelindung diri (PPE) yang sesuai semasa pemasangan.

5. Pemasangan

5.1 Pemasangan Rel DIN

The KETOTEK energy meter is designed for standard 35mm DIN rail installation. Simply clip the meter onto the DIN rail in your electrical panel.

5.2 Arahan Pendawaian

Refer to the wiring diagram below for correct connection. The meter requires both a live (L) and neutral (N) connection for its own power supply and for voltage measurement. For current measurement, one of the load cables (either live or neutral) must pass through the integrated current transformer hole.

• Sambungkan vol input ACtage (Live and Neutral) to terminals 1 and 2 of the meter.
• Pass one of the load cables (Live or Neutral) through the current sensing hole on the right side of the meter. The direction in which the cable passes through the hole does not affect the measurement.
• Pastikan semua sambungan selamat dan terlindung dengan betul.
• For three-phase systems, connect only one live wire and the neutral wire to the meter for measurement.

6. Operasi

6.1 Hidupkan

Once properly wired and power is supplied, the meter will automatically power on and display the measured electrical parameters on its LCD screen.

6.2 Mod Paparan

The meter cycles through different display screens, showing various parameters such as voltage, current, active power, energy, frequency, and power factor. The colorful HD LCD ensures clear readability.

6.3 Data Reset

To reset the accumulated electrical energy (kWh) data, press and hold the blue "RESET" button on the front panel for approximately five seconds. The energy value will reset to zero.

The meter automatically stores the accumulated energy data even if power is interrupted. When power is restored, it will continue to accumulate from the last saved value.

7. Penyelesaian masalah

• Tiada Paparan: Semak sama ada input AC voltage is correctly connected to terminals 1 and 2 and within the specified range (AC 40-300V). Ensure power is supplied to the circuit.
• Current/Power Reading is Zero: Verify that one of the load cables is correctly passed through the integrated current transformer hole. Ensure there is an active load drawing current.
• Bacaan Tidak Tepat: Confirm that the wiring is correct according to the diagram. Ensure the meter is not exposed to strong electromagnetic interference.
• Paparan berkelip: While some minor fluctuations in decimal values are normal for real-time measurements, ensure stable power supply. If flickering is excessive or constant, recheck connections.

8. Penyelenggaraan

• Pastikan meter bersih dan bebas daripada habuk. Gunakan kain lembut dan kering untuk membersihkan. Jangan gunakan pembersih atau pelarut yang kasar.
• Regularly inspect wiring connections to ensure they remain tight and secure.
• Elakkan hentaman fizikal atau menjatuhkan peranti.
• No user-serviceable parts inside. Do not attempt to open or repair the meter yourself.
