Environmental Conditions for Installation
- טעמפּעראַטור: The maximum ambient temperature should not exceed 40°C (104°F), and the minimum should not be lower than -5°C (23°F). The average temperature within a 24-hour period should not exceed 35°C (95°F).
- הייך: The installation site's altitude should not be higher than 2000 meters (6562 feet).
- הומידיטי: When the maximum temperature reaches 40°C (104°F), the relative humidity should not exceed 50%. At lower temperatures, such as -5°C (23°F), higher relative humidity is permissible. For example, at 25°C (77°F), the relative humidity can be up to 90%. Special measures should be taken to address occasional condensation on the product's surface due to temperature changes.
אַפּערייטינג ינסטראַקשאַנז
The Focket NLQ3 125 4P Automatic Transfer Switch offers both automatic and manual operation modes, ensuring reliable power transfer.
אָטאַמאַטיק מאָדע
In automatic mode, the switch continuously monitors the normal power supply. If the normal power supply becomes abnormal (e.g., power outage, voltage drop), the switch will immediately transfer the load to the backup power supply. This millisecond switching ensures uninterrupted power, maintaining continuity, reliability, and safety of the power supply.
מאַנואַל מאָדע
The device can also be operated manually using the integrated handle. This allows for controlled switching between power sources for maintenance or testing purposes. Ensure the switch is in the "Manual" position before attempting manual operation.

טראָובלעשאָאָטינג
If you encounter issues with your automatic transfer switch, consider the following common problems and solutions:
| פּראָבלעם | מעגלעך סיבה | לייזונג |
|---|---|---|
| סוויטש גייט נישט אויטאמאטיש אריבער. | Normal power supply not detected as abnormal; switch in manual mode; internal fault. | Verify normal power supply status. Ensure switch is set to "Auto" mode. Check wiring connections. If problem persists, contact support. |
| Switch makes unusual noises or smells. | Overload; loose connections; internal component failure. | Immediately disconnect power. Do not operate. This indicates a serious issue. Contact a qualified electrician or manufacturer support. |
| Power supply is intermittent after transfer. | Loose wiring; insufficient backup power; faulty switch. | Check all wiring connections for tightness. Ensure backup power source is stable and sufficient for the load. If issues continue, seek professional assistance. |
וויכטיק: If you experience issues such as the device burning out or self-destructing as reported by some users, immediately disconnect power and do not attempt to repair it yourself. Such incidents indicate a critical failure and require professional attention or replacement. Always prioritize safety.
