Installation
AC Power Supply
All standard components of the Transmitter NV820x are interconnected by wires. Thus, the
rack merely needs to be connected to one AC power supply.
ATTENTION!
Before you connect the transmitter, disconnect the power supply cable from the supply.
Requirements
AC supply voltage - three-phase current 230 V/400 V ± 15%
AC supply frequency - 47 Hz to 63 Hz
ATTENTION!
Make sure that the AC supply voltage is within the specified range and check all power
cables for possible damage.

Installation
Connection of Transmitter Ground
ATTENTION!
The rack must be connected to the station's main ground terminal.
A grounding bolt is located on the bottom of the transmitter rack, well accessible from the
front.
) Secure the external ground conductor to the grounding bolt using the ground nut.
Fig. 8 Ground connection on transmitter rack
6.2
Connection of AC Power Cable
The external AC power supply is connected directly to the main switch. The main switch
completely isolates the rack from the AC supply. Use a five-wire cable (3 phases, neutral
and PE conductor)

2. Secure the supplied strain relief for the AC supply cable in place as shown.

3. Loosen the locking screws on the switch housing so that you can easily insert the cables.
4. Insert the cables into the corresponding openings and fasten them in place with screws.
5. Using a phase-sequence indicator, determine the phase sequence of the rotating field
(should be clockwise).
If the phase sequence is correct, continue to the next step. If the phase sequence is not
correct, reverse the cables and measure the phase sequence again.
6. Remount cover and rotary switch with screws.

Connection of External Equipment
You can connect the following equipment to the transmitter's power distribution board:
 External fan
 External dummy antenna
The exact dummy plugs needed are already installed in the proper positions.
1. Remove the required dummy plug from the power distribution board.
2. Connect the cables of the external equipment to the plug.
3. Reinsert the plug in the power distribution board.

Installation
Amplifiers
When the transmitter is shipped from the factory, one or two exciters and an NETCCU® are
already mounted in the rack. In contrast, the amplifiers must be installed in the rack later.
7.1
Installing the Amplifier
ATTENTION!
Always make sure that the power supply is disconnected before commencing any installation work on the transmitter rack; this will prevent injury from electric shock and damage to
the equipment.
ATTENTION!
Always install the amplifiers in pairs since they are quite heavy (approx. 25 kg).
Note
Before installing the amplifier, make sure that the ventilation covers on the amplifier slots
provided in the frame are open on both sides. Remove the covers if necessary.
Install the amplifiers in the sequence top to bottom.
1. Carefully remove the amplifier from its packaging.
2. Select the installation position provided for the amplifier in the transmitter rack.
3. Place the amplifier on the guide rails and slide it carefully into the rack as far as it will go.
The amplifier is taken to the connections by means of guide pins on the rear panel.
4. Fasten the amplifiers in place using the four screws of the two front brackets on the rack.
5. To install additional amplifiers, repeat steps 1 through 4.

Installation
Connection of Antenna/Dummy Antenna to RF
Connector
The connection flanges for the antenna cables are uniformly 1 5/8" EIA for 325 W to 1.95 kW
TV transmitters; they are located on the roof of the transmitter. Depending on the transmitter station (one or more transmitters), either the antenna (RF cable or RF transmission line)
or an RF connection is connected directly to a multi-transmitter combining filter.
ATTENTION!
Do not connect the antenna until you have completed all measurements, because the link
to the antenna produces emissions.
8.1
Connection of Antenna
Connect the antenna as follows:
) Using the four screws (M8, 35 mm), fasten the ready-made coaxial cable located on the
station in place. To prevent the screw connection from locking in place, insert a plain
washer and spring-lock washer.
Note
2099.9595.72
In regions with high humidity, the supplied rubber ring can be inserted in the groove between the two EIA flanges.

8.2
Connection of Dummy Antenna
Connect the dummy antenna only for maintenance and repair purposes.
With some dummy antennas that have coolant monitoring and excess temperature monitoring, the monitoring equipment can be connected to the transmitter. As a temporary installation (e.g. during switchover), the main protection loop can be used here (X41.1 and
X41.2 in the power distribution).
) Remove the jumpers and connect the monitoring unit.
If you are using an RF patch panel that allows you to switch between the antenna and dummy antenna by means of an RF U-link (permanet installation), you should attach the dummy
antenna monitoring unit to the standby protection loop (X41.3 and X41.4 in the power distribution). For this to be done, the messages of the patch panel must also be sent to the
controller.
