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).
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)
