Functional Devices (RIB) PSH100A Enclosed Power Supply User Manual

1. Úvod

This manual provides instructions for the installation, operation, and maintenance of the Functional Devices (RIB) PSH100A Enclosed Single 100VA 120 to 24Vac UL Class 2 Power Supply. The PSH100A is designed to convert 120 Vac input power to a stable 24 Vac output, suitable for various low-voltage applications requiring a UL Class 2 power source.

Před instalací a provozem si prosím pečlivě přečtěte tento návod k obsluze, abyste zajistili bezpečné a efektivní používání produktu.

2. Bezpečnostní informace

WARNING: Risk of Electric Shock. Disconnect power before installation or servicing.

• Instalaci a servis smí provádět pouze kvalifikovaný personál.
• Dodržujte všechny národní a místní elektrické předpisy.
• Nepřekračujte stanovený objemtaga jmenovité proudy zařízení.
• V případě potřeby zajistěte řádné uzemnění.
• Nepoužívejte zařízení, pokud se jeví poškozené.

3. Nastavení a instalace

The PSH100A power supply is housed in a metal enclosure for protection and ease of mounting.

3.1. Montáž

The enclosure is designed for surface mounting. Select a suitable location that is dry, well-ventilated, and accessible for wiring and inspection. Use appropriate fasteners (not included) to secure the enclosure to a wall or panel through the pre-drilled mounting holes.

3.2. Zapojení

Ensure all power is disconnected at the circuit breaker before proceeding with wiring.

1. Open the enclosure cover to access the terminal block.
2. Input Wiring (120 Vac): Connect the 120 Vac line voltage to the designated input terminals. Typically, these are marked "L" (Line) and "N" (Neutral) or similar. Ensure proper polarity.
3. Output Wiring (24 Vac): Connect the load requiring 24 Vac to the designated output terminals. These are usually marked "24VAC" or similar.
4. Základy: Connect the system ground to the grounding terminal within the enclosure, if provided and required by local codes.
5. Ověřte, zda jsou všechna připojení bezpečná a správná.
6. Zavřete kryt skříně.

4. Návod k obsluze

Once the PSH100A power supply is correctly installed and wired, restore power to the circuit. The unit will immediately begin providing 24 Vac power at its output terminals. The PSH100A is designed for continuous operation and does not require any user interaction during normal use.

• The power supply is a Class 2 device, meaning its output is inherently limited to prevent electric shock and fire hazards.
• Ensure the connected load does not exceed the 100 VA (Volt-Ampere) rating of the power supply.

5. Údržba

The PSH100A power supply is generally maintenance-free. However, periodic inspection is recommended to ensure optimal performance and safety.

• Roční kontrola: Visually inspect the enclosure for any signs of physical damage, corrosion, or overheating.
• Kontrola zapojení: With power disconnected, verify that all wiring connections remain tight and secure.
• Čištění: If necessary, gently clean the exterior of the enclosure with a dry, soft cloth. Do not use liquid cleaners or solvents.

WARNING: Do not attempt to open or repair the internal components of the power supply. Refer all servicing to qualified personnel.

6. Řešení problémů

If the PSH100A power supply is not functioning as expected, refer to the following troubleshooting steps:

• No Output Voltage:
  • Verify that the 120 Vac input power is present at the input terminals using a multimeter.
  • Check the circuit breaker supplying power to the unit.
  • Zkontrolujte všechna kabelová spojení, zda nejsou uvolněná nebo poškozená.
  • Ensure the load connected to the output is not short-circuited or drawing excessive current, which could trigger internal protection.
• Přehřívání:
  • Ensure the power supply is installed in a location with adequate ventilation.
  • Verify that the connected load does not exceed the 100 VA rating of the power supply. Excessive load can cause overheating.

If the issue persists after performing these steps, contact Functional Devices, Inc. technical support.
