2.1 Installation
Precautions
The DX2400 amplifier is capable of in excess of 1500W sustained operation. Several precautions
need to be taken to insure the rest of your installation is capable of handling high power levels.
•
Station AC Power Supply: Recommend 10 gage wiring and 30A circuit with NEMA
outlet installed in accordance with the National Electric Code and all local ordinances and
zoning regulations. Consult a qualified electrician if you have any questions.
•
Make certain your antenna installation can handle at least 3KW of peak power if
sustained 1500W operation such as FM or 375W carrier AM is planned. Dishtronix
manufactures conservatively designed high power baluns. Use a high quality, low loss
coax such as RG-8X, etc. Antenna wire should not be smaller than #12 AWG copper.
•
Station Grounding: Equipment must be grounded properly. The installation diagrams
show the ground system used at Dishtronix. Each piece of equipment must be bonded
individually to the ground and not daisy chained. The ground straps may be fabricated
from the flattened braid of RG-8X coax, or may be copper strap. Braids are fastened with
a clamp to a 1” OD piece of copper plumbing pipe that runs behind the operating position
desk. The braids may also be soldered to the pipe. This intermediary ground is then
strapped to the external station ground rods by more braids. Two inch slit copper rolls are
available through various sources that can be used in place of the braid. Consult the
ARRL Radio Amateurs Handbook and the National Electric Code Handbook for
information on ground systems and high power installations.
•
RF exposure
. It is your responsibility as the station licensee to ensure that your
installation meets specified RF safety levels. Consult with CFR Title 47, Part 97 of the
Federal Code of Regulations and the latest edition of the ARRL Radio Amateurs
Handbook for more information.
•
Station Operating Position: Warning, the DX2400 Amplifier and LPS4800 linear supply
is heavy, approaching 200 lbs. Ensure that your table or rack is sturdy and can safely
handle the weight before installation.
•
CAUTION!
The DX2400L1 is designed for operation ONLY with the LPS4800 Linear
Power Supply, or the SPS4800 Switching Power Supply! The finals of the DX2400
operate at 72 Volts and require peak currents approaching 80 Amperes.
•
DO NOT ATTEMPT TO OPERATE THIS AMPLIFIER FROM A 12 VOLT
(MOBILE) POWER SUPPLY!
•
DO NOT OPERATE THIS AMPLIFIER FROM ANY SUPPLY OTHER THAN
THE APPROVED DISHTRONIX POWER SUPPLY.
Use of an unauthorized power
supply voids the warranty.
•
DO NOT OBSTRUCT THE VENT OR FAN OPENINGS!
Cooling air is vital to the
proper life and operation of this amplifier. Remember when transmitting at 1500W that
you need to remove approximately 1500W of heat from the cabinet!
•
CAUTION!
If you are using a high power transceiver with more than 100W of RF
output you may need to activate the internal 3dB attenuator. See Section 3.6 and 3.10.2.
OVERDRIVING YOUR AMPLIFIER MAY VOID YOUR WARRANTY!
