Terra UA410 User manual

Product description
The output amplier UA410 is intended to amplify and summarize signals in modular system as well as stand-alone unit.
The UA410 has wide range of output level selection, which includes interstage and input gain adjustments.
Two selectable input modes: input + input test point or two inputs.
Both output and switchable input test points are directional.
The output amplier is intended for indoor use only.
Safety instructions
Installation of the amplier must be done according IEC60728-11 and local safety standards.
The amplier is powered from power supply unit (PSU) +12 V. This voltage is not dangerous to life.
Output of PSU +12 V must have a short circuit protection.
Any repairs must be done by a qualied personnel.
Do not plug the PSU +12 V into the mains socket until all modules cables have been connected correctly;
The mains socket of PSU +12 V must be easily accessible;
To disconnect the amplier, disconnect the PSU +12 V from the mains.
The amplier shall not be exposed to dripping or splashing water and no objects lled with liquids, such as vases, shall
be placed on it;
Avoid placing amplier next to central heating components and in areas of high humidity;
No naked ame sources, such as lighted candles, should be placed on amplier;
If the amplier has been kept in cold conditions for a long time, keep it in a warm room no less than 2 hours before
plugging into the mains;
The ventilation should not be impeded by covering the ventilation openings with items, such as newspapers, table-cloths,
curtains;
Mount the amplier in vertical position;
From top, front and bottom of installed amplier must be at least 10 cm free space.

Installation instructions
1. Read the safety instructions rst.
2. Mount the amplier on the DIN rail or on the wall following the mounting instructions listed below.
3. Connections of the cables must be made according to the diagram in Figure 2. There are two ways for power supply
connection: 12 V DC voltage can be supplied through DC input terminal or units of the system can be joined together using
power distribution bus while only one of them connected to 12 V power supply unit.
4. Power supply can be connected only when all connections are nished.
Operating
Input mode can be selected using input mode switch (3). One or two inputs modes are available. The one input mode
offers input test feature, while the two inputs mode enables to summarize and amplify signals from both: RF input and auxilary
input. The amplier offers wide range of attenuation. Attenuation interstage switch (1) allows to provide output signal level
attenuated by 10 dB. Fine tunning of the output level can be achieved using attenuation rotary switch (2), which broadens
attenuation range up to 15 dB with 1 dB steps adjustment.
