Chapter 1: Product Overview 7

Safety Precautions

To avoid potential video and/or keyboard problems when using Avocent products:

• If the building has 3-phase AC power

, ensure that the server 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 extension cord in any Avocent product configuration.

• Test AC outlets at the server and monitor for proper polarity and grounding.

• Use only with grounded outlets at both the server and monitor. When using a backup

Uninterruptible Power Supply (UPS), power the server, the monitor and the AMX switch off

the supply.

NOTE: The AC inlet is the main disconnect.

DC installation safety considerations

As a safety precaution, install this product in an area with limited or controlled access. A readily

accessible disconnect device that is suitably approved and rated shall be incorporated in the field

wiring. Connect field wiring from earth ground to the screw terminal marked with the ground symbol.

Terminals will accommodate wiring from 26 to 12 AWG (up to 2.5 mm2 maximum cross section).

Strip each wire, insert it in the square opening in the terminal block and tighten the screw above it to

a maximum of 70 ounce-inches (0.5 Nm) using either a flat or Phillips-head screwdriver.

Rack mount safety considerations

• Elevated Ambient Temperature: If installed in a

closed rack assembly, the operation

temperature of the rack environment may be greater than room ambient. Use care not to exceed

the rated maximum ambient temperature of the unit.

• Reduced Air Flow: Installation of the equipment in a rack should be such that the amount of

air

flow required for safe operation of the equipment is not compromised.

• Mechanical Loading: Mounting of the equipment in the ra

ck should be such that a hazardous

condition is not achieved due to uneven mechanical loading.

• Circuit Overloading: 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: Reliable earthing of rack m

ounted equipment should be maintained. Pay

particular attention to supply connections other than direct connections to the branch circuit

(for example, use of power strips).
