4.1 Mounting
The TVPS3-100AS is designed for wall mounting. Ensure a stable and dry location with adequate ventilation.
4.2 Wiring Diagram
Refer to the wiring diagram below for proper connection. Ensure all connections are tight and correct before applying power.
Figure 5: Wiring Diagram and Product Dimensions
- Connect the incoming Neutral (N) and Live (L1, L2, L3) lines to the 'IN' terminals.
- Connect the outgoing Neutral (N) and Live (T1, T2, T3) lines to the 'OUT' terminals, which lead to your load.
- Ensure the N wire is connected correctly to the N terminal.
5. Operating Instructions
5.1 Dual Work Modes: Synchronous (SYN) and Asynchronous (ASY)
The device supports two primary operating modes:
Figure 6: Illustration of Dual Operating Modes
- Synchronous Mode (SYN): In this mode, all three phases (L1, L2, L3) operate as a single unit. The relay opens or closes for all three phases simultaneously based on the protection settings. This mode is suitable for protecting a single three-phase load.
- Asynchronous Mode (ASY): In this mode, each phase (L1, L2, L3) operates independently. The device acts as three individual single-phase protectors, allowing separate protection and control for each phase.
Note: When operating in ASY mode, phase sequence protection and voltage unbalance protection are not active.
Figure 7: ASY Mode does not include Phase Sequence or Voltage Unbalance Protection
5.2 Setting Parameters
To adjust the protection parameters, use the Menu (M) and Adjustment (▲/▼) keys. The following table outlines the adjustable parameters, their default factory settings, and their functions.

7. Troubleshooting
If you encounter issues with the TVPS3-100AS, refer to the following common problems and solutions:
- No Display/Power: Check the main power supply and all wiring connections. Ensure the device is receiving input voltage.
- Frequent Tripping: Review your protection settings (over-voltage, under-voltage, over-current). Ensure they are appropriate for your electrical system and load. Check for actual power fluctuations or overloads in your system.
- Incorrect Readings: Perform manual calibration as described in Section 5.3.
- Protection Indicators Active: If >U, <U, >I, SYN, ASY, or L1/L2/L3 indicators are lit, it signifies a detected fault condition. Refer to Section 3.2 for indicator meanings and the operating range table for parameter adjustments.
- Phase Loss: If the phase-loss protection is enabled and a phase is lost, the device will cut off the line. Verify the incoming phases.
If problems persist, contact customer support.
