Wiring Instructions:

Refer to the wiring diagrams below for correct connection of the normal power source (Source A), backup power source (Source B), and the load output. Ensure all connections are secure and tightened to prevent loose contacts and overheating.

1. Normal Power (Source A): Connect the primary utility power lines to the 'Normal Power A' input terminals.
2. Backup Power (Source B): Connect the secondary power source (e.g., generator) lines to the 'Reserve Power B' input terminals.
3. Load Output: Connect the electrical loads (circuits to be powered) to the 'Load Output' terminals.
4. Control Lines: Connect common control lines and alternate control lines as indicated in the diagram for proper automatic operation.
5. Grounding: Ensure the ATS is properly grounded according to electrical codes.

This diagram illustrates connections for common power supply, backup power, load output, and control lines. For the 2P 100A model, refer to the 2-pole diagram.

6. Operating Instructions

The ZipcOm W2R ATS offers both automatic and manual operation modes.

Automatic Mode:

1. Set the selector switch on the ATS to the 'Auto' position.
2. When normal power (Source A) is present, the ATS will connect the load to Source A.
3. If normal power fails or becomes abnormal, the ATS will automatically detect the condition and transfer the load to the backup power source (Source B), provided Source B is available and stable.
4. Once normal power is restored and stable, the ATS will automatically switch the load back to Source A.

Manual Mode:

1. To manually switch between power sources, set the selector switch to the 'Manual' position.
2. Carefully rotate the red handle to select either 'Source A' or 'Source B' as desired.
3. Caution: Manual operation should only be performed when necessary and with full awareness of the power sources' status. Ensure the load can handle the selected power source.

7. Maintenance

The ZipcOm W2R ATS is designed for minimal maintenance. Regular inspections can help ensure its longevity and reliable operation.

• Periodic Inspection: Annually inspect the ATS for any signs of physical damage, loose connections, or discoloration due to overheating.
• Cleaning: Keep the ATS free from dust and debris. Use a dry, soft cloth for cleaning. Do not use liquid cleaners.
• Terminal Tightness: Periodically check and re-tighten all terminal screws to ensure good electrical contact.
• Professional Check: Consider having a qualified electrician inspect the unit every few years, especially in critical applications.
