3.2 SWITCHING ON GROUND STATION ON SITE
3.2.1 Status of Installation
Before operation, the system must be completely installed as follows:
− ADS−B Ground Station (AS 680 or AS 682), installed as per section 3.1.
− Power supply, installed.
− Antennas installed and cabling complete.
− Network connected.
− Mains AC voltage or, if DC version, DC voltage must be in accordance with assigned input voltage
range.
3.2.2 Status of the System
− Local DC supply and local mains supply, if AC/DC version used, off.
− DC switch on SPU and SM in off−position ("0"); with AC/DC version: also mains switch at back-
panel of SPU to off ("0").
NOTE: The Ground Station and the Site Monitor are normally configured and preset for operation
in the factory before delivery. This means that normally no basic software installations
have to be performed. Depending on antenna characteristics and local radio environment
an adaptive adjustment of the receiver sensitivity (SPU, RXU) may be necessary. Refer
for the appropriate measures to section 3.2.6 and perform the steps for setting the value
with the oscilloscope.
3.2.3 Uninterruptible Power Supply (UPS), Startup and Operation
NOTE: Regard also the information and the safety instructions of the original manufacturer user
manual of the Xantos UPS equipment.
WARNING
Risk of electric shock. Even after the unit is disconnected from the mains power supply
(building wiring socket outlet), components inside the UPS system are still connected to
the battery and are still electrically live and dangerous.
Before carrying out any kind of servicing and/or maintenance, disconnect the batteries
and verify that no current is present.
Only persons adequately familiar with batteries and with the required precautionary mea-
sures may exchange batteries and supervise operations. Unauthorised persons must be
kept well away from the batteries.
− Verify that the security switch on the back side of the battery extensions is in ON position.
− Switch on local mains AC supply.
As soon as the UPS is connected to mains supply, the UPS outlet sockets are now powered. This
is indicated by the LED LINE and BYPASS.
Fully charge the batteries of the UPS system by leaving the UPS system connected to the mains
for approx. 1 to 2 hours. The UPS system can also be use directly without charging it, but the stored
energy time may then be shorter than the nominal value specified.
− Press the ON−button "I" on the front panel to start the UPS system.
Load capacity LEDs first light up simultaneously, then one after the other. After a few seconds the
INVERTER−LED lights up and the BYPASS−LED turns off. The UPS is now functioning normally.
