INSTALLATION
The installation of any electrical equipment should be made by trained
technicians who know the risks related to handling electrical supplies.
Before proceeding with the installation, it is necessary to verify that the
equipment is in compliance with the rules of the Country where the unit will
operate. Before connecting the transmitter to the AC source, it is necessary to
verify that the voltage range reported in the back of the unit matches the
voltage of the AC supplied. Here are some important details about electrical
systems.
ELECTRICAL SYSTEM
Depending upon the exact location of the site, electricity is subject to more or
less fluctuations in power. Fluctuation in voltage is not the only issue you can
have with electricity. Most of the time, you can have spikes and peaks of
power that last for very short intervals but that are sufficient to destroy your
device. There are many devices on the market that protect the AC line and
they are all useful (surge suppressors, stabilizers etc.). However, only one is
really mandatory to avoid disasters caused by the AC. It is called an
ISOLATION TRASFORMER. The isolation transformer creates a physical
separation from the input of your AC line to the trasmitter. Anything
destructive that would come through the AC, stops in the transformer and
cannot reach the transmitter.
This device is indispensable because, in the last 10 years, the broadcast
industry has developed new smaller power supplies that are very light. They
did this to allow the units to be lighter for easy trasportation. Unfortunately,
the side the downside is that the big transformers that were located inside
the units protecting them, have been removed. The new AC-DC power
supplies do not give any sort of protection. The isolation transformer is
necessary to give that protection. A big isolation transformer installed where
the AC enters the site protect not only one specific device, but all of the
equipment that are in the same building.
