IMPORTANT SAFETY INFORMATION
The installation of a rotatable antenna system on a tower is a dangerous and potentially life-threatening task if
due care is not taken. DX Engineering shall not be held liable for any accident or injury involved in the
installation or operation of the RT4500HD rotator. It is the responsibility of the customer to ensure the
installation is completed by an experienced and reliable installation company complying with standard safety
practices and using the best practices for working on or near a tower.
SAFELY working on a tower system is THE MOST IMPORTANT thing. Your installation team must follow all
safety requirements to avoid any injury or possible death from an accident. If you and your team do not have
the experience or safety equipment required, you should contact a qualified tower/antenna installation team.
The DXE-RT4500RT weighs approximately 22 pounds – ensure no one is located below the tower working
area either on the ground or on the tower. If the rotator it is accidently dropped while working on the tower
injury or death may occur if someone is struck by the falling rotator.
NOTE: The lifting handle must always be used when transporting the rotator and
when raising it up the tower.
Do NOT lift the rotator by the top round rotator plate.
A snap ring holds the top plate in position and it is not designed to hold the
weight of the rotator. If you hold the rotator by the top plate, you risk having the
snap ring fail and the rotator will then drop away from the top plate.
A tower must never be installed in a position where it could fall across power lines in the event of a
catastrophic failure during a windstorm or other environmental disaster. Follow all safety related items when
installing or working on a tower – Safety First.
The control cable attached to the DX Engineering rotator could, in the event of a nearby or direct lightning
strike carry lethal voltages down the cable and into your radio room. DX Engineering strongly recommends the
installation of suitable lightning arrestors on all rotator control lines and coaxial cables entering your radio room
from your antenna installation. Additionally a thrust bearing by-pass kit and lightning rod should be installed to
further help mitigate lightning damage.
If an electrical storm should be approaching your area, quickly disconnect the control cable from the rear of the
rotator’s control box and disconnect the AC cable from the wall outlet. Disconnect the coaxial cables from the
antennas as well. Only do this if the lightning is NOT in your immediate area, as you could be killed instantly if
lightning should strike while you are holding a cable.
NOTE: If you have any doubts about your ability to install this
rotator, seek out the services of a professional antenna – tower
installation company.
