Note:
to ensure both the safety of the operators and correct operation of the
equipment, it is essential that the mains system is earthed and properly connected
to the equipment.
Useful tips for a correct connection:
• Prepare suitable earthing of the electrical system. This offers both direct
protection, as it prevents shocks when direct contact is made with the
metal casings of the equipment, and indirect protection, as it cuts off
the supply of energy when dispersion occurs due to poor insulation.
This can be done independently also with an earthing rod and inspection pit
installed by the qualified personnel of a specialised company.
• Provide internal lightning protection such as a surge arrester (internal SPD) or
a circuit breaker, to be installed by qualified personnel in the distribution panel.
This solution allows to protect from violent atmospheric electric discharges that
hit the surrounding ground up to several kilometres.
• Provide internal protection against disturbances on the distribution line such as
EMI filters or line voltage stabilizers, to be installed by qualified personnel in the
distribution panel, which can filter disturbances caused by electrical equipment
and sudden surges on the line, as well as permit voltage control.
5.1.4 Audio and RF connections
Prepare the following connection (valid for both functional tests and final
commissioning):
√
For functional tests only:
• a dummy load with 50 Ohm impedance and of appropriate power (minimum
2500W for
TEX2503TFT
).
• Coaxial cable with BNC connectors for connecting the interlock signal to the
load protection.
√
Connection cable kit including:
• RF cable for the output towards the load / antenna (50 Ohm coaxial cable with
standard 7/8” type connector).
• Audio cables between transmitter and audio signal sources.
CAUTION: risk of burns due to RF. Before connecting the antenna cable,
make sure that the equipment cannot emit RF at the output.
CAUTION: For reasons of electromagnetic compatibility, only double shielded
cables should be used at the RF output.
