Safety Information

Please read and understand all safety instructions before operating the PS4x4PROUSB. Failure to do so may result in electric shock, fire, or damage to the unit or connected equipment.

• Do not expose this appliance to rain or moisture.
• Do not open the unit. There are no user-serviceable parts inside. Refer all servicing to qualified service personnel.
• Ensure the power source voltage matches the unit's requirements (115VAC).
• Do not overload the unit. The maximum output wattage is 1800 Watts.
• Always connect the unit to a grounded power outlet.
• Keep ventilation openings clear to prevent overheating.

Setup

1. Unpacking

Carefully remove the PS4x4PROUSB unit and all accessories from its packaging. Inspect the unit for any signs of damage that may have occurred during shipping. If damage is found, contact your dealer immediately.

2. Rack Mounting

The PS4x4PROUSB is designed for standard 1U rack mounting. Secure the unit into your equipment rack using appropriate rack screws. Ensure adequate ventilation around the unit.

4. Connecting Devices

The PS4x4PROUSB provides nine power outlets: eight on the rear panel and one on the front panel. Additionally, two USB charging ports are available on the front. Connect your equipment to these outlets. The rear outlets are switched, meaning they are controlled by the main power switch. The front outlet and USB ports may have independent control or be always-on, depending on the specific model variant.

3. Advanced Power Filtering (APF)

The unit incorporates ART’s Advanced Power Filtering (APF) technology. This system utilizes both common mode and differential mode topologies in series to minimize unwanted noise and interference, providing cleaner power to your sensitive equipment.

4. Surge Protection

The PS4x4PROUSB provides surge protection to safeguard your connected gear against power spikes and surges. In the event of a significant power surge, the protection circuit will activate to prevent damage to your equipment.

Maintenance

1. Cleaning

To clean the unit, use a soft, dry cloth. Do not use abrasive cleaners, solvents, or waxes. Ensure the unit is powered off and disconnected from the main power supply before cleaning.

2. General Care

Regularly inspect the power cable and connections for any signs of wear or damage. Ensure the unit is placed in a well-ventilated area to prevent overheating. Avoid spilling liquids on the unit.

Troubleshooting

• No Power to Outlets:
  • Check if the main power switch on the front panel is in the ON position.
  • Verify that the power cable is securely connected to both the PS4x4PROUSB and a live wall outlet.
  • Check the circuit breaker on the unit (if present) and reset if tripped.
  • Ensure the wall outlet is functioning by plugging in another device.
• Noise or Interference:
  • While the unit features Advanced Power Filtering, some external interference sources may still affect sensitive equipment. Ensure all audio cables are properly shielded and routed away from power cables.
  • Test equipment individually to isolate the source of the noise.
• Surge Protection Indicator:
  • If a surge protection indicator light (if present) changes color or turns off, it may indicate that the surge protection components have been compromised by a significant power event. In such cases, the unit may still provide power, but its surge protection capabilities might be reduced or non-existent. Contact customer support for further assistance.
