Mounting brackets are visible at both ends for rack installation.
5.1 Rack Mounting
- Identify an available 1U space in your standard 19-inch server rack.
- Align the mounting brackets on both ends of the PDU with the rack posts.
- Secure the PDU to the rack using appropriate rack screws (not included). Ensure it is firmly attached.
5.2 Surface Mounting (e.g., under desk, wall)
- Choose a flat, stable surface for mounting.
- Use the mounting brackets on the PDU as a template to mark screw locations.
- Drill pilot holes if necessary.
- Secure the PDU to the surface using appropriate screws (not included). Ensure it is firmly attached and stable.
5.3 Connecting to Power
- Once the PDU is securely mounted, plug its 9-foot power cord into a grounded 125V AC wall outlet.
- The power switch on the PDU should illuminate when power is supplied and the switch is in the 'ON' position.
6. Operating Instructions
6.1 Powering On/Off
- To turn on the PDU and supply power to its outlets, press the red illuminated power switch to the 'ON' position. The switch will light up.
- To turn off the PDU and cut power to all connected devices, press the power switch to the 'OFF' position. The light will extinguish.
6.2 Connecting Devices
- Plug your electronic devices into the 8 AC outlets on the PDU.
- Ensure that the total power draw of all connected devices does not exceed the PDU's maximum rating of 1875W (15A at 125V).
6.3 Surge Protection
This PDU includes 900 Joules of surge protection to shield your connected equipment from voltage spikes. In the event of a significant power surge, the surge protection feature will activate to absorb the excess energy. If the surge protection is compromised, the 'SurgePro' indicator light (if present and functional) may turn off or change color, indicating that the unit no longer provides surge protection. In such a case, the unit should be replaced.
7. Maintenance
- Cleaning: Disconnect the PDU from the power source before cleaning. Use a soft, dry cloth to wipe the exterior. Do not use liquid cleaners or aerosols.
- Inspection: Periodically inspect the power cord and the PDU for any signs of damage, such as frayed wires, cracks, or loose connections. If damage is found, discontinue use and replace the unit.
- Outlet Caps: The unit may come with safety caps for unused outlets. Use these to prevent dust accumulation and accidental contact.
