6. Setup jeung Instalasi
Proper installation is crucial for the safe and reliable operation of the transfer switch. This device is designed for DIN rail mounting.
Sateuacan Instalasi
- Ensure all power sources are disconnected at the main breaker before beginning installation.
- Pariksa yén voltage and current ratings of the transfer switch match your electrical system requirements.
- Prepare the installation location, ensuring it is dry, well-ventilated, and easily accessible.
Diagram Wiring

This diagram illustrates the correct wiring connections for the transfer switch. It shows the input terminals for primary power (N1, L1) and backup power (N2, L2), and the output terminals (N, L) to the load. The diagram also labels the LED indicators for L1 output, L2 output, overvoltage, jeung undervoltage, as well as the menu/reset and manual ON/OFF buttons.
Léngkah-léngkah Instalasi
- Mount the DIN rail securely in your electrical panel or enclosure.
- Attach the transfer switch onto the DIN rail.
- Connect the primary power source (N1, L1) to the designated input terminals.
- Connect the backup power source (N2, L2) to the designated input terminals.
- Connect the load (N, L) to the output terminals.
- Ganda-pariksa sadaya sambungan pikeun tightness jeung correctness.
- Once all wiring is complete and verified, restore power to the system.
7. Operasi
The MARSTEK transfer switch offers both automatic and manual operation modes.
Modeu otomatis

In automatic mode, the switch prioritizes the primary power source (L1). If L1 fails or experiences voltage fluctuations (undervoltage atanapi overvoltage), the switch will automatically transfer the load to the backup power source (L2). When L1 is restored and stable, the switch will automatically transfer the load back to L1.
Modeu Manual

The transfer switch can be manually operated using the buttons on the front panel.
- To close L1: Press the button labeled "L1" (often indicated by an up arrow or similar icon). Press again to open L1.
- To close L2: Press the button labeled "L2" (often indicated by a down arrow or similar icon). Press again to open L2.
In manual mode, the automatic transfer function is overridden. Ensure you understand the implications of manual switching before use.
LED Display and Indicators
The LED display provides real-time information about the system status.
- The main display shows voltage readings for the active power source.
- L1: Indicates L1 output is active.
- L2: Indicates L2 output is active.
- >V: Overvoltage lampu indikator.
- <V: Undervoltage lampu indikator.
- M: Menu selection/Reset button.
- SET: Manual ON/OFF button.

| Masalah | Mungkin Cukang lantaranana | Solusi |
|---|---|---|
| Alat henteu hurung. | Taya kakuatan input; wiring salah; kasalahan internal. | Check main breakers and power sources. Verify all wiring connections. If the problem persists, contact support. |
| No automatic transfer. | Device in manual mode; power source within acceptable limits; fault in L1 or L2 detection. | Ensure the device is set to automatic mode. Check voltage levels of both L1 and L2. Contact support if automatic transfer fails despite correct settings. |
| Overvoltage (>V) or Undervoltage (<V) indicator lit. | Masukan voltage di luar rentang anu ditangtukeun. | Pariksa voltage of the active power source. The device will automatically switch if the voltage is outside the set parameters (AC140V overvoltage, AC90V undervoltage). Address the power source issue. |
| Overcurrent protection triggered. | Load exceeds the 63A current rating. | Reduce the connected load. Ensure total current draw does not exceed 63 Amps. |
