2.2.6 Routing Cables
Wiring is affected by temperature, humidity, and vibration extremes. You should do the following
installation.
CAUTION Power supply cords and cables must be protected. Do not run cords
where they can be stepped on. Protect cables against pinching and
chafing. Pay special attention to locations where the cables enter or exit
an enclosure or make a sharp bend.
• Secure all cables at close intervals along their entire lengths.
• Protect cabling with added sheathing or padding anywhere cabling passes through a
hole or lies against an obstruction.
• Provide flex relief at any location where the cable must change direction sharply, to
maintain a smooth bend and prevent kinking.
• Provide strain relief at each connector to absorb any pulling forces on the cable and
prevent damage to the connector.
• If long lengths of cable are required, you may need a UHF amplifier or gain block.
Contact Vislink for specific cable types and lengths to use in your application. For specific cable
types and lengths to use in your DXL8000, contact Customer Support; see

2.2.7 Power Requirements
The DXL8000 operates on 115/230 VAC, 50/60 Hz and - 48 VDC. Fuse ratings for the AC and
DC power sources are as follows:
Operating Voltage Fuse Rating Power Consumption
230 VAC, 50/60 Hz 1.0A, 250V AGC, Fast Blow
120W maximum
115 VAC, 50/60 Hz 2.0A, 250V AGC, Fast Blow
- 48 VDC, 1.2 A, 3 A, Slow Blow 57.6 W
CAUTION Ensure that the power being supplied matches the power required by
the equipment. You can find power ratings for equipment on a rating
plate, usually on the rear panel. Ensure that the electrical supply is
protected by over-current protection devices as required by the
applicable electrical codes. If necessary, consult a licensed electrician.
DC Power Operations
When you are operating an unprotected Transmitter, Receiver and ODU system your DC input
should incorporate a properly grounded, 1.2 A, 57.6 W regulated power supply. It is crucial that
overload, over voltage and over temperature protection that shuts down the power supply
should be built in. The incidental increase in amperage should shut down the power supply and
then restore power upon recovery to avoid equipment damage.
For a protected system, the 48 VDC is supplied by the DXL Hot Standby switch. For more
information, refer to the
