Mounting Options

The TDM can be configured either in a stand-alone or in a multiple mounted version. The stand- alone version is installed in a 70A Data Mounting aluminum housing that is equipped with plastic front and rear covers. A maximum of eight TDMs may be installed in the 71A Data Mounting.

The stand-alone version can be mounted on a surface or desk top near the associated data equipment. The multiple-mounting carrier unit is normally installed in an auxiliary cabinet.

Power

Both mounting arrangements require power from a 115-volt AC receptacle to power the TDM.
