SECTION 1.2: PRE-INSTALLATION TASKS
This section provides a list of tasks that you must perform prior to delivery and installation of the VX
series transmitter.
Preparing for Installation
To prepare for installation of an VX series transmitter, perform the following tasks:
1. Ensure that the correct transmitter configuration is ordered. Check the ac power requirements,
preset frequency, and other options. If your ac power source is different than the factory
configuration (See
“Ac Power” on page 1.1.2 for example), contact Nautel to arrange
reconfiguration.
NOTE
:
For VX150, VX300 and VX600 transmitters, the ac input voltage range is 90 - 265 V ac. For VX1,
VX1.5 and VX2 transmitters, RF output power is limited to approximately 33% of rated power when the
ac input voltage is between 90 - 185 V ac
.
2. Select a location for the transmitter in the transmitter room. Determine whether additional
heating, ventilating or cooling capacity is needed at the site. Identify any special requirements
regarding air flow around the cabinet (for example, ducting hot air away from the cabinet, or
bringing in external cooling air).
3. If this is an upgrade or replacement transmitter (that is, if the site is already set up for a
transmitter), proceed to
Step 7 . If you are upgrading a site, verify the feedline, the lightning
protection systems, and the ac power service.
NOTE
:
Be aware of lightning protection issues when installing ac power and RF feedline. Lightning
protection is essential to protect both personnel and equipment at your site. Refer to the Lightning
Protection section of Nautel’s Recommendations for Transmitter Site Preparation Manual
.
4. Install the ac power service into the planned transmitter location, and select a location for the ac
surge protection panel (if purchased) near the transmitter. Consult with an electrician prior to
receiving the transmitter regarding local electrical codes and special considerations based on
transmitter power consumption and requirements. For detailed information, see
“Electrical power”
on page 1.5.1 .
5. Install lightning protection on the antenna tower. Refer to the
Recommendations for Transmitter
Site Preparation Manual
, provided with the transmitter.
