Mounting the MLS 608 D Series Switchers
If the device is to be rack mounted, it may be easier to do so before cabling it, depending
on the ease of access to the rear panel after mounting. Four rubber feet are included with
the unit. Install the feet only if the unit is to be mounted on a tabletop (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 MLS 608 D Series switcher in a rack.
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) 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).
Rack Mounting
To rack mount the switcher, insert screws into the brackets and attach them to the sides of
the switcher. Then secure it to the the rack (see figure below).
