Terra OD005 User manual

Product description
Optical receivers OD005, OD005P (in text – receiver) are intended to convert signals from optical to electrical. Devices
are equipped with Optical Level Control and optical input power indicator as well as bidirectional output test point to simplify
measurement, adjustment and troubleshooting.
OD005P receiver is powered from the mains 230 V~. OD005 receiver is powered from external +6 V DC power supply
unit (PSU) through F-type connector.
Devices are intended for indoor use only.
Suitable for moderate and tropical climates.
Safety instructions
Installation of the receiver must be done according IEC60728-11 and national safety standards.
Any repairs must be done by a qualied personnel.
The OD005P is powered from mains 230 V~. The voltage is dangerous to life.
The OD005 is powered from external +6 V DC power supply unit (PSU) through F-type connector. Output of PSU +6 V
must have a short circuit protection. Follow external PSU safety instructions during installation.
To ensure safe operation of the receivers follow these instructions:
do not remove the cover of the power supply section of OD005P, without disconnecting the unit from the mains supply;
do not plug the receiver into the mains supply if the power cord or plug are damaged;
do not plug the receiver OD005P and the PSU of OD005 into the mains supply until all cables have been connected correctly;
to disconnect the OD005P from the mains completely, disconnect plug from the mains socket;
to disconnect the OD005, disconnect the PSU from mains;
the mains socket must be easily accessible;
receiver 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 the receiver next to central heating components and in areas of high humidity;
no naked ame sources, such as lighted candles, should be placed on receiver;
if the receiver 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 receiver in vertical position with RF connections underneath;
from top, front and bottom of installed receiver must be at least 10 cm free space.
An optical connector after disconnection emits optical radiation.
Avoid looking directly into beam, laser light can cause eye injuries and result in permanent loss of vision.

INSTALLATION INSTRUCTIONS
Read the product description and safety instruction rst.
The receiver should be mounted vertically with cable RF output underneath in order to ensure good ventilation conditions.
The receiver must be xed with steel screws Ø 4-5 mm. The screws are not included in a package.
Fiber installation should be done very carefully. Bending radius of bers must be not less 25 mm. All optical connectors
and adaptors should be cleaned before connecting them.
Plug the receiver into the mains after all cables have been connected correctly.

Operating and adjusting
Optical level control (OLC) is active at optical input power -6 .. 0 dBm. The output level remains constant (adjusted by user
using discrete 0/5/10 dB switch and ne tuned with 0 .. 5 dB regulator) while optical input power uctuates in range of -6 .. 0 dBm.
The receiver owns optical input power indicator formed from 3 LED. Note the table below for detailed description.
