User's Manual

of protection from bad weather conditions. However, it is not permitted to install the
TTPA in bad weather conditions. If the bad weather conditions are of a short
duration, and the TTPA and all other connectors that are to be connected during the
installation are protected, the installation may continue not less than one hour after the
adverse conditions have ended.
Dimensions
Weight is 12 kilos for TTPA unit, 3 kilo for clamping unit.
Mounting equipment
A standard mounting kit is delivered with each TTPA. It contains one holder used for
both pole mounting and wall mounting, and screws needed for the mounting. The
brackets for pole mounting fit poles with diameters of between 50 and 120 mm.
A torque meter is needed for tightening bolts and connectors. Amalgamated tape for
insulating the connectors is not required, but may be used.
Checklist before mounting and installation
• Are all the necessary adapter cables available and are they long enough?
Normally, a 1 meter long adapter cable is needed for the connection between the
TTPA and the antenna.
• Are the 7/16 connectors to be connected to the TTPA of the correct sex?
• Are brackets of the right size available?
• Are sufficiently long grounding straps available?
• Is the place where the TTPA is to be mounted the optimal location, considering
cable lengths and length of grounding straps?
• Is there a distance of free air of at least 0.5m from top and bottom sides, and 0.2
m from all other sides except the backside?
Installation procedure for TTPA
Before the actual installation is started, read the safety information at the beginning of
this guide.
Phase 1: The first phase of the installation, that is the mounting of the TTPA and
grounding cable, can be carried out with the BTS still active.
If the TTPA unit is to be mounted on a wall, you’ll need to take away the four tabs
for pole mounting on the mounting plate (see picture below). The easiest way is to
bend them away with a pair o pliers.
