5. Enstalasyon ak fil elektrik
The TOQ6-63PV is designed for Din Rail mounting. Follow these steps for safe and correct installation:
- Montaj: Securely attach the device to a standard 35mm Din Rail within an appropriate electrical enclosure.
- Power Source 1 (City Power) Connection: Connect the main utility power supply to the terminals labeled "City Power" (N2|A2). Ensure correct L (Live) and N (Neutral) connections.
- Power Source 2 (PV Grid-connected) Connection: Connect the PV grid-connected power supply to the terminals labeled "PV Grid-connected" (N1|A1). Ensure correct L (Live) and N (Neutral) connections.
- Koneksyon chaj: Connect the electrical load (devices to be powered) to the "LOAD" terminals at the bottom of the switch.
- Sekans Faz: ENPÒTAN: The input power supply must be connected in the correct phase sequence. Refer to the diagram on the device for guidance.
- Sere Tèminal yo: Use a screwdriver to securely tighten all screw-type terminals to prevent loose connections and potential arcing. Recommended torque: 2.5 N·m.

6. Operasyon
The TOQ6-63PV offers both automatic and manual operation modes.
6.1. Operasyon Modes
- Mòd oto: When the selector switch is set to "Auto", the device will automatically detect the presence and quality of both power sources (City Power and PV Grid-connected) and switch to the preferred or available source. Typically, it prioritizes one source (e.g., PV) and switches to the other (e.g., City Power) if the primary source fails or is out of specification.
- Mòd manyèl: When the selector switch is set to "Manual", you can manually select the desired power source using the toggle switch (I or II).
- Pozisyon I: Selects Power Source 1 (PV Grid-connected).
- Pozisyon II: Selects Power Source 2 (City Power).
6.2. Limyè Endikatè
- IU (Red LED): Indicates the status of Power Source 1 (PV Grid-connected). Lit when Power Source 1 is active.
- IIU (Green LED): Indicates the status of Power Source 2 (City Power). Lit when Power Source 2 is active.
- Load ON (Red LED): Indicates that power is being supplied to the load. Lit when the load is receiving power from either source.

7. Antretyen
The TOMZN TOQ6-63PV is designed for minimal maintenance. However, periodic checks are recommended:
- Enspeksyon vizyèl: Annually inspect the device for any signs of physical damage, discoloration, or loose connections.
- Sere Tèminal: Periodically check and re-tighten all terminal screws to ensure secure electrical contact.
- Netwayaj: If necessary, gently clean the exterior of the device with a dry, soft cloth. Do not use liquids or abrasive cleaners.
- Kondisyon anviwònman: Ensure the operating environment remains within specified temperature and humidity ranges to prolong device life.
NAN. Depanaj
If you encounter issues with your TOQ6-63PV, consider the following common troubleshooting steps:
- Pa gen pouvwa pou chaje:
- Check if both input power sources (City Power, PV Grid-connected) are active and their respective indicator lights (IU, IIU) are lit.
- Ensure the device is in "Auto" mode or manually switched to an active source in "Manual" mode.
- Verifye tout koneksyon fil elektrik yo byen fèm epi kòrèk.
- Check for tripped circuit breakers upstream of the ATS.
- Device Not Switching Automatically:
- Confirm the selector switch is firmly in the "Auto" position.
- Check the status of both input power sources. The automatic transfer relies on the availability of both sources.
- Asire volim kontwòl latage (220V~) is present and stable.
- Overheating/Unusual Odors:
- Immediately disconnect power to the device.
- This indicates a serious fault. Do not attempt to operate the device. Contact a qualified electrician.
For issues not resolved by these steps, consult a qualified electrician or contact TOMZN customer support.
