Mounting the Annotator 300
If the Annotator 300 is to be rack mounted, it is important to mount the device before
cabling it. Four rubber feet are included with the unit. Install the feet only if the unit is to be
used on a table top (see "Tabletop Placement" below).
Tabletop Placement
For tabletop placement, install the self-adhesive rubber feet/pads (provided) onto the four
corners of the bottom of the device.
UL Guidelines for Rack Mounted Devices
The following Underwriters Laboratories (UL) guidelines pertain to the safe installation of
the Annotator 300 in a rack.

Rack Mounting
Mount the Annotator 300 to a rack using the pre-installed mounting brackets.
To install the device, line up the screw holes on the brackets on both side of the device
with the screw holes in the rack so the device is level (see figure 2). Secure the device to
the rack using the provided screws.

Elevated operating ambient temperature — If installed in a closed or multi-unit rack
assembly, the operating ambient temperature of the rack environment may be greater
than room ambient temperature. Therefore, install the device in an environment
compatible with the maximum ambient temperature (Tma = +122 °F, +50 °C) as
specified by Extron.
Reduced air flow — Install the equipment in a rack so that the amount of air flow
required for safe operation of the equipment is not compromised.
Mechanical loading — Mount the equipment in the rack so that a hazardous condition
is not achieved due to uneven mechanical loading.
Circuit overloading — Connect the equipment to the supply circuit and consider the
effect that circuit overloading might have on overcurrent protection and supply wiring.
Appropriate consideration of equipment nameplate ratings should be used when
addressing this concern.
Reliable earthing (grounding) — Maintain reliable grounding of rack-mounted
equipment. Pay particular attention to supply connections other than direct
connections to the branch circuit (for example, use of power strips).
