Terra Electronics SA91L Manual

PRODUCT DESCRIPTION
SAT multichannel amplifiers (in text - amplifier) SA91L, SA91DL are parts of medium or large SMATV networks.
SA91L is designed as a launch amplifier and usually is installed at the begining of network. Its main purposes are:
- to equalize the power of signals in different lines;
- to make amplitude pre-correction of signal for compensation its loss in network;
- to supply voltage to LNB converters and other network elements like interstage amplifiers SA91DL, MV series multiswitches,
terrestrial path amplifiers and so on.
Terrestrial TV input has LTE signal suppression filter
SA91DL is designed as interstage amplifier with remote powering. Generally it is installed inside cascaded type networks
to compensate signal loss in trunk lines. It could be used as a launch amplifier if additional power supply is plugged to relative
connector.
The housing of amplifiers meets more stringent screening requirements according to EN50083-2, class A.
According to the standard ETSI EN 303 354 V.1.1.1, this TERR TV band amplifier type is Launch, selectivity clasification 0.
The amplifiers are intended for indoor use only.
SAFETY INSTRUCTIONS
Installation of the amplifiers must be done according IEC60728-11 and national safety standards.
Amplifier SA91L is powered from mains 230 V~ (this voltage is dangerous to life) and SA91DL - from line 12...20 V DC
through input connectors or auxiliary DC input.
Any repairs must be done by a skilled personnel.
Amplifier SA91L is double isolated from mains 230 V~.
To avoid the electric shock follow these instructions:
Do not remove the cover of the power supply section, without disconnecting the amplifier from the mains supply.
Do not plug the amplifier into the mains supply if the power cord or plug is damaged.
Do not plug the amplifier SA91L into the mains supply until all cables have been connected correctly.
The mains socket must be easily accessible.
Avoid placing amplifier next to central heating components, near highly combustible materials and in areas of high humidity.
If the amplifier 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.
Do not insert any objects into ventilation openings.
The ventilation should not be impeded by covering the ventilation openings with items, such as newspapers, table-cloths,
curtains.
Mount the amplifier on not flammable wall or in not flammable installation box in vertical position (SA91L) with power supply
unit on the right side. Mount in locations where children not likely to be present. Shields of cables must be connected to main
potential equalization bus.
The amplifier must be fixed with steel screws Ø 4-5 mm. The screws are not included in a package.
From top, front and bottom of installed amplifier must be at least 10 cm free space.
