If you want to protect only one specific device and you want to know what
size of tranformer you will need, you can multiply the output watt power of
your device by 2.5 and you will have the Watts needed by your isolation
transformer. (Example: for a 1000 W transmitter you need at least a 2.5
KWatt
isolation transformer). If you want to protect more devices you should add
the wattage of every unit and multiply by 2.5.
Once you have your transformer installed, you need to verify how good
your ground system is. Every good electrician should have a proper
device to measure the ground. Money invested in measuring
your ground can fix problems and avoid bigger expenses in the future.
Every rack and every unit must be connected to ground.
Once that the electrical connections have been verified, you need to
connect the antenna to the transmitter through the coaxial cable. Verify
that the connector is properly tighten and, in case you have a rigid
coaxial cable feeding the transmitter, install a pigtail with proper power
capability and more flexibility so that you do not put too much pressure on the
connector.
Before proceeding to operate, we strongly recommend that you make
double sure an adequate grounding system has been set. Nicom will not
be held responsible for damages to persons and materials if these
guidelines are not followed.
The positioning of the transmitter inside the room is equally important. If the
unit is placed in a rack, make sure there is enough space around for the air to
circulate. Remember that fresh air is positioned lowest in the room.
Place your transmitter as low as possible, but not too close to the floor to
avoid damages due to humidity. Leave at least 2 feet of space
behind the transmitter to allow the warm air flow to circulate without
obstruction. We highly recommend to keep the room cool with an air
conditioning system, so that the unit can work at a constant temperature
without excessive humidity (between 60 and 75 degrees); a temperature
over 75 degrees causes the unit to work in a stressed environment which
can negatively impact the life and performance of the unit.
