5. Setup and Installation

Important: All installation work must be performed by a qualified electrician in accordance with all national and local electrical codes.

Power Disconnection: Ensure all power sources (utility grid and generator) are completely disconnected and locked out before beginning installation.
Mounting: Mount the ATS on a standard Din Rail within an appropriate electrical enclosure. Ensure adequate ventilation and clearance for wiring.
Wiring Connections:
- Connect the primary power source (e.g., City Power) to the "Source A" terminals.
- Connect the secondary power source (e.g., Generator) to the "Source B" terminals.
- Connect the load (circuits to be powered) to the output terminals of the ATS.
- Connect the control wiring as per the wiring diagram (refer to Figure 2 for an example of control signal connections). Ensure correct polarity for control signals.
Grounding: Properly ground the transfer switch according to local electrical codes.
Verification: Double-check all connections for tightness and correctness. Ensure no bare wires are exposed.

6. Operating Instructions

The FCNGEVBH ATS supports both automatic and manual operation modes.

6.1 Automatic Mode

Ensure the manual/auto selector switch (red handle) is set to the "Auto" position.
When the primary power source (Source A) is present, the switch will automatically connect the load to Source A.
If Source A fails, the switch will detect the power loss and, after a pre-set delay (if configured externally), initiate the transfer to Source B (Generator). The generator must be started and stable for the transfer to occur.
When Source A is restored, the switch will detect its return and, after a pre-set delay, transfer the load back to Source A.

6.2 Manual Mode

Manual operation allows you to physically select the desired power source.

To operate manually, move the red selector handle to the "Manual" position.
Once in manual mode, you can physically move the switch lever to select "Source A" or "Source B" as needed.
Caution: Ensure the selected source is stable and safe before transferring the load manually.
To return to automatic operation, move the red selector handle back to the "Auto" position.

7. Maintenance

Regular maintenance helps ensure the longevity and reliable operation of your ATS.

Periodic Inspection: Annually inspect the transfer switch for any signs of physical damage, loose connections, or overheating.
Cleaning: Keep the unit clean and free from dust and debris. Use a dry, soft cloth for cleaning. Do not use liquid cleaners.
Terminal Check: Periodically check all terminal connections for tightness. Loose connections can cause overheating and potential failure.
Functionality Test: It is recommended to periodically test the automatic transfer function by simulating a power outage (if safe and feasible) to ensure the system operates as expected.
Professional Service: For any complex issues or internal component inspection, contact a qualified electrician.

8. Troubleshooting

This section provides solutions to common issues. For problems not listed here, contact a qualified technician.

Problem	Possible Cause	Solution
Switch does not transfer automatically.	Selector switch in "Manual" position. No power from secondary source (generator). Control wiring issue. External controller malfunction.	Set selector switch to "Auto". Check generator operation and output. Verify control wiring connections. Inspect external controller.
No power to load after transfer.	Source power not present or unstable. Loose power connections. Internal fault in ATS.	Check both power sources. Inspect and tighten all power terminal connections (with power off). Contact qualified service personnel.
Overheating of terminals.	Loose connections. Overload condition. Incorrect wire gauge.	Disconnect power and tighten all connections. Reduce load or ensure load is within ATS capacity. Verify wire gauge is appropriate for 100A current.
