TP T Series Transmitters • Installation and Operation
PRELIMINARY
Mounting the transmitters
The TP T Series transmitters can be set on a table; mounted on a rack shelf; or 
mounted through or under a desk, podium, or tabletop. The following optional 
mounting kits are available:
•  RSM 100 — Rack shelf mount kit for twisted pair products (#70-123-01)
•  RSB 129 — 1U, 9.5" deep basic rack shelf (#60-604-01, -02)
•  RSU 129 — 1U, 9.5" deep rack shelf kit (#60-190-01, -02) 
•  MBU 125 — Under-desk mount kit (#70-077-01)
•  MBD 129 — Through-desk mount kit (#70-077-02)
Tabletop use
Four self-adhesive rubber feet are included with the unit. For tabletop use, affix 
one foot at each corner of the bottom of the transmitter and place the unit in the 
desired location.
Rack mounting
UL rack mounting guidelines
The following Underwriters Laboratories (UL) guidelines pertain to the safe 
installation of the equipment in a rack.
1.  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, 
install the equipment in an environment compatible with the maximum 
ambient temperature (Tma = +113 °F, +45 °C) specified by Extron. 
2.  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. 
3.  Mechanical loading — When mounting the equipment in the rack, ensure 
that uneven mechanical loading does not create a hazardous condition.
4.  Circuit overloading — Connect the equipment to the supply circuit and 
consider the effect that circuit overloading might have on overcurrent 
protection and supply wiring. Also consider equipment nameplate ratings 
when addressing this concern.
5.  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 procedure
To mount the transmitter on a 9.5 inches deep rack shelf,
1.  If rubber feet are attached to the bottom of the unit, remove them.
2.  Fit the RSM 100 mounting bracket around the transmitter and attach it to the 
unit using one mounting hole on each end. 
3.  Mount the bracket containing the unit onto the rack shelf, using two 
4-40 x 3/16 inch screws in the two mounting holes in the bottom of the 
bracket to secure it.
4.  Install blank panel(s) or other unit(s) on the rack shelf as desired.
5.  Attach the rack shelf to the rack using the supplied bolts.
