To set up the TECO T-verter N2 Series inverter, follow these steps:

1. Installation Location
- Avoid corrosive liquids, gases, dust, metal scraps, and electromagnetic interference.
- Minimize vibration; use an anti-rattle mounting device if needed.
- If installed in an enclosed control panel, use an external fan for additional cooling.
- Place external fans directly over the top of the inverter.

2. Mounting and Orientation
- Position the front side of the inverter facing forward.
- Ensure the top of the inverter is facing upward for better heat dissipation.
- Maintain proper ventilation within a temperature range of -10°C to +40°C.

3. Electrical Connections
- Install a molded-case circuit breaker (MCCB) between the power source and the inverter.
- Do not connect a magnetic contactor, phase capacitor, or burst absorber between the inverter and the motor.
- Use appropriate wire gauges and terminal screws as specified for the model.

4. Grounding
- Properly ground the T-verter enclosure with a grounding resistance of less than 100Ω.
- Use a grounding wire with a diameter of at least 2mm².

5. Remote Operator Installation (if applicable)
- Turn off power and ensure the T-verter power indicator is off.
- Remove the digital operator from the T-verter.
- Insert the remote cable adapter and connect both ends of the remote cable.
- Secure the digital operator using accessory screws.

Following these steps ensures proper setup and operation of the TECO T-verter N2 Series inverter.
