5. Quick Installation and Use Guide

This chapter contains the instructions necessary for installing and using the machine.
Should any part not be completely clear, for example when the machine is used for
the first time, we recommend you carefully read the complete description contained
in this manual.

5.1 Preparation

Unpack the exciter and before carrying out any other operation make sure no damage
has been caused during transport. In particular, make sure all connectors are in perfect
condition.

Check that the power supply voltage value matches the available mains voltage. The
protection fuses can be accessed externally through the back panel (see fig. 6.2). To
check its condition or if replacement is required, remove the fuseholder with a
screwdriver. Use the following type of fuse:

6.3 A5x20

Make sure the 

TEX150-LCD/S

 switches are in the “OFF” position. The exciter features

two switches: one built into the VDE base for the mains power supply cable, which
cuts off mains power completely, and the second is located on the front panel and
bypasses the machine’s switching power supply.

Connect the exciter RF output to the antenna cable or to a fictitious load able to
dissipate the power generated by the 

TEX150-LCD/S

.

CAUTION: if no load is present, do not touch the output RF connector during machine
operation to avoid electric shock and electrocution.

Connect the mains cable to the MAINS connector located on the back panel (see fig.
6.2).

CAUTION: the power connector is a terminal board; make sure that the cable is not
live when making the connection.

CAUTION: the mains system must feature grounding to ensure both the safety of the
operators and correct operation of the device.

Connect the audio signals and RDS/SCA of their sources to the 

TEX150-LCD/S

input connectors following the instructions contained in the diagram in fig. 6.2.
