INSTALLATION
This unit is designed for mounting in a standard nineteen inch rack. When picking a location in the rack,
considerations must be given to the lengths of the RF coaxial cable, as well as cooling.
Mount the unit where dust and other debris are not likely to clog the cooling fans. Avoid mounting the amplifier
directly above hot pieces of equipment that could artificially raise the amplifier temperature.
Connect the radio transmitter to the “RF INPUT” N connector and an antenna to the “RF OUTPUT” 7/16 DIN
connector on the amplifier. Use 50 Ohm coaxial cable with appropriate RF power rating.
Plug the AC line cord into the system AC power receptacle.
For safety, make sure the rack and all equipment connecting to the amplifier have proper AC grounds. Do not
rely on coaxial cable shields for AC grounding.
Assure the installation has proper lightning protection.
MAINTENANCE
There are two maintenance tasks to be performed on the TPL Communications HMS Series RF Amplifiers.
These tasks are listed below.
1.) Perform regular inspections of the air intake and exhaust fans. Clean or clear any dust or debris that may
have collected. This will prevent the amplifier from overheating.
2.) Every month record the data displayed on the HMS status display on the Front Panel Meter Reading Data
Sheet in APPENDIX 1 of the HMS users manual. This will aid the technicians in servicing the amplifier should a
problem develop.
