The MTP 4T 15HD RS is 1U high and a full rack wide. It is rack mountable, or it can be
placed on a table or other furniture. Rubber feet and rack mounting hardware are included.

Tabletop Placement

For tabletop use, attach one of the self-adhesive feet to each corner of the bottom side of
the unit and place the unit in the desired location.

Rack Mounting

UL requirements

The following Underwriters Laboratories (UL) requirements pertain to the installation of the
unit into a rack.

Elevated operating ambient temperature — If the equipment is 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, consider installing the
equipment in an environment compatible with the maximum 122° F (50° C) 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 of 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 (grounding) — 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 (such as the use of power strips).
