- Protect wiring from sharp edges and high temperatures.
- Use appropriate personal protective equipment (PPE) when working with electrical components.
3. What's in the Box
The package for the YORK S1-02530889000 Transformer typically includes:
- One (1) YORK S1-02530889000 Transformer (Replacement Part)
Inspect the contents upon receipt to ensure all items are present and undamaged. Contact your supplier immediately if any components are missing or damaged.
4. Installation and Setup
The YORK S1-02530889000 Transformer is designed for specific applications and should be installed by a qualified technician in accordance with local electrical codes and the equipment manufacturer's instructions.
4.1 Pre-Installation Checks
- Confirm the transformer's specifications (voltage, frequency, VA rating) match the system requirements.
- Ensure the mounting location is secure, dry, and provides adequate ventilation.
- Verify that the power supply is disconnected at the source before beginning installation.
4.2 Mounting
The transformer features an integrated mounting bracket. Secure the transformer firmly to a stable surface using appropriate fasteners. Ensure the mounting is robust enough to support the transformer's weight (approximately 1.5 pounds) and withstand any operational vibrations.

4.3 Wiring Connections
Refer to the wiring diagram provided with your equipment or on the transformer's label for correct connections. The transformer has clearly marked terminals:
- Primary (Input) Terminals: Typically labeled "120V" and "COM" (Common). Connect the 120V AC power supply to these terminals.
- Secondary (Output) Terminals: Typically labeled "24V" and "COM" (Common). These terminals provide the 24V AC output.
Important:
- Ensure all connections are tight and secure to prevent loose contacts and potential arcing.
- Use wire gauges appropriate for the current draw and local electrical codes.
- Double-check all wiring before restoring power.

5. Operation
Once properly installed and wired, the YORK S1-02530889000 Transformer operates automatically to convert the input voltage. When 120V AC is supplied to the primary terminals, the transformer will provide a stable 24V AC output at its secondary terminals, suitable for powering control circuits or other low-voltage components in compatible systems.
The transformer is designed for continuous operation within its specified ratings. No user intervention is required for its basic function after installation.
6. Maintenance
The YORK S1-02530889000 Transformer is a robust component designed for long-term reliability with minimal maintenance. However, periodic inspection is recommended to ensure optimal performance and safety.
6.1 Inspection Schedule
- Annually: Inspect the transformer and its connections.
- As needed: If any operational issues are suspected.
6.2 Inspection Steps
- Disconnect Power: Always de-energize the circuit before inspection.
- Visual Check: Look for any signs of physical damage, discoloration, or overheating on the transformer body and wiring.
- Connection Integrity: Check all terminal connections for tightness. Loose connections can cause overheating and arcing.
- Cleanliness: Ensure the transformer is free from dust, dirt, or debris that could impede heat dissipation. Use a dry, soft brush or compressed air for cleaning.
- Environmental Conditions: Verify that the operating environment remains within acceptable temperature and humidity ranges.
CAUTION: Do not attempt to disassemble the transformer. There are no user-serviceable parts inside.
7. Troubleshooting
This section provides guidance for common issues that may arise with the transformer. For complex problems or if you are unsure, consult a qualified technician.
| Problem | Possible Cause | Solution |
|---|---|---|
| No output voltage (0V AC) | No input voltage; Blown fuse/breaker; Open primary winding; Loose connections. | Verify input power supply. Check and reset circuit breaker or replace fuse. Inspect primary wiring for continuity. Tighten all connections. |
| Incorrect output voltage | Incorrect input voltage; Overload; Faulty transformer. | Measure input voltage to ensure it is 120V AC. Reduce load on the secondary side. If input is correct and load is within limits, the transformer may be faulty and require replacement. |
| Transformer is hot to the touch | Overload; Poor ventilation; Short circuit in secondary circuit. | Check the load on the secondary side to ensure it does not exceed the transformer's VA rating. Ensure adequate airflow around the transformer. Inspect secondary wiring for short circuits. |
| Humming or buzzing noise | Normal operation (slight hum); Loose laminations; Overload. | A slight hum is normal. If excessive, check for loose mounting or laminations. Verify load is not exceeding VA rating. |
