Safety Precautions
To avoid potential video and keyboard problems when using Avocent products:
• If the building has 3-phase AC power, ensure that the computer and monitor are on the same
phase. For best results, they should be on the same circuit.
To avoid potentially fatal shock hazard and possible damage to equipment, please observe the
following precautions:
• Do not use a 2-wire power cord in any Avocent product configuration.
• Test AC outlets at the target device and monitor for proper polarity and grounding.
• Use only with grounded outlets at both the target device and monitor. When using a backup
Uninterruptible Power Supply (UPS), power the target device, the monitor and the
DSR1024
switch from the UPS.
NOTE: The AC inlet is the main power disconnect.
• Consideration should be given to the connection of the equipment to the supply circuit and the
effect that overloading of circuits might have on overcurrent protection and supply wiring.
Consider equipment nameplate ratings for maximum current.
• Reliable earthing of equipment should be maintained. Pay particular attention to supply
connections other than direct connections to the branch circuit (for example, use of power
strips). Reliable earthing of equipment should be maintained. Pay particular attention to supply
