Mounting Options

Tabletop use (all except AAP models)

The non-AAP MTPs come with self-adhesive rubber feet attached to the four corners of the bottom. Set the MTP on a horizontal surface.

Rack mounting (all except AAP models)

For optional rack mounting, mount the MTP on any of the following rack shelves:

•VersaTools® 19" 1U rack shelf kit (part #60-190-20) (figure 2-8)

•VersaTools 19" basic 1U rack shelf (part #60-604-20)

•6" deep 1U rack shelf kit (part #60-190-10)

•6" deep basic 1U rack shelf (part #60-604-10)

•Standard universal 1U rack shelf kit (part #60-190-01) (figure 2-9)

UL requirements

The following Underwriters Laboratories (UL) requirements pertain to the installation of the MTP transmitter or receiver into a rack (figure 2-8).

1.Elevated operating ambient — 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. Therefore, consider installing the equipment in an environment compatible with the maximum ambient temperature (Tma) specified by the manufacturer.

2.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.

3.Mechanical loading — Mounting of the equipment in the rack should be such that a hazardous condition is not achieved due to uneven mechanical loading.

4.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.

5.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).
