Twin Tower Mounted Am lifier (TMA) Auto By ass
PACKAGE CONTENTS
lease find the following products inside the box:
• (1) Twin Tower Mounted Amplifier
• (2) Hose Clamps (For pole mounting – diameter 40-110mm)
• (1) Installation Instructions.
RECOMMENDED TOOLS
The following tools are needed for proper installation
• 5 mm Allen Key – for fixation of the hose clamps onto the
tower [Torque 5.5 Nm (4.1 ft-lb)]
• 10 mm Spanner – for fixation of the ground cable to the TMA
• Additional Tools – for fixation of the ground cable onto the
TMA, for fixation of the ground cable onto the tower grounding
point, for tightening the 7/16 connector swivels and for
mounting the TMA onto the wall
IMPORTANT SAFEGUARDS
IMPO TANT: All national safety rules and regulations must be
followed during installation and maintenance of the TMA.
!Make sure that the Base Station is sending the proper DC input
voltage (10-30VDC) through the feeder cables. The DC input
voltage MUST be applied on both the TMA BTS ort 1 and the
BTS ort 2.
!It is important that no RF and DC power is floating in the
associated RF feeder cables and, in general, that no power is
radiated from the tower or site during the TMAs installation.
!RFS recommends using the shortest jumper cables from the TMA
ANT orts to the Antenna in order to optimize system
performance.
!RFS recommends applying additional anti-corrosion protection
and using best practices when products are installed in areas
with high-salt concentration, on chimneys (SO2) or other
extreme harsh environment, to lengthen the product lifetime.
!RFS recommends using RFS accessories and cables to ensure the
best installation.
1. Check that F signals and DC power coming from the
Base Station are OFF/disconnected.
2. Fix the hose clamps onto the TMA.
3. Mount the TMA to the pole by tightening the hose clamps
with 5.5 Nm (4.1 ft-lb) torque.
4. Attach a grounding cable (RFS Models CA020-2 or CA030-2 –
Not Included) to the grounding screw.
5. Tighten the ground cable nut with 4 Nm (3 ft-lb) torque.
6. Adjust the length of the ground cable and fix it onto the tower
ground connection.
7. Connect the jumpers between the 7-16 connectors of the
antennas and the 7-16 connectors (ANT 1 and 2) of the
TMA(s). Connect the jumpers between the 7-16 connectors
(BTS 1 and 2) of the TMA(s) and the 7-16 connectors of the
feeder cables.
8. When attaching the jumper cable 7-16 connector swivel to the
TMA 7-16 female connector it is mandatory that the jumper
cable meets with the 7-16 female connector of the TMA
straight in line. ress the inner part of the jumper cable
connector into the TMA connector and maintain this pressure
when turning the swivel. Hereby the swivel will fit the thread
of the female connector correctly and it will run smoothly.
Tighten the swivel by hand.
Note: No angular torque from the jumper cable is allowed at
any time.
9. Tighten the connector assembly with 25 Nm (18.4 ft-lb)
torque.
10. Seal all connectors. The tape around the connectors must
connect with the TMA top/bottom plates for correct weather
protection. See section “Connector Insulation” details.
