Rack Mount Safety Instructions (UL)
When installing the chassis in a rack, be sure to implement the following
Safety instructions recommended by Underwriters Laboratories:
• Elevated Operating Ambient - If installed in a closed or multi-unit rack
assembly, the operating ambient temperature of the rack environment may be
greater than room ambient. Therefore, consideration should be given to
installing the equipment in an environment compatible with the maximum
ambient temperature (Tma) specified by the manufacturer.
• Reduced Air Flow - Installation of the equipment in a rack should be such
that the amount of air flow required for safe operation on the equipment is not
compromised.
• Mechanical Loading - Mounting of the equipment in the rack 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 the circuits
might have on overcurrent protection and supply wiring. Appropriate
consideration of equipment nameplate ratings should be used when
addressing this concern.
• Reliable Earthing - Reliable earthing of rack-mounted equipment should be
maintained. Particular attention should be given to supply connections other
than direct connections to the branch circuit (e.g., use of power strips.)
¾ To attach the device to a 19-inch rack, take these 2 steps:
1. Position the device in your 19-inch rack and align the left-hand and right-hand bracket
holes to holes (of your choosing) in the vertical tracks of the 19-inch rack.
2. Use standard 19-inch rack bolts (not provided) to fasten the device to the frame of the
rack.
AudioCodes recommends using two additional (not supplied) rear mounting brackets to
provide added support.
Note: Users assembling the rear brackets by themselves should note the
following:
• The distance between the screws on each bracket is 26.5 mm.
• To attach the brackets, use 4-40 screws with a maximal box penetration
length of 3.5 mm.
