TECHNICAL INSTRUCTIONS
Section 2 PRE-INSTALL, INSTALLATION, SETUP & CONFIGURATION
2.1 ENVIRONMENT
REQUIREMENTS
Consider the following environment
requirements when preparing the VR-Link
for installation.
2.1.1 Dimensions
The VR-Link is an enclosed EIA standard
cabinet mount assembly. See Figure 1-1 for
dimensions.
2.1.2 Clearances
If mounting the unit in a standard 19-inch
equipment cabinet, allow a minimum of two
inches at the top of the unit for adequate air
circulation. Allow sufficient rear clearance for
interconnections between the VR-Link and
other components of the transmitter system.
2.1.3 Cooling
The maximum chassis temperature of the
VR-Link must not exceed 50°C (122°F). To
satisfy this requirement:
•
Do not allow the room’s ambient
temperature to exceed 50°C (122°F) at
sea level. Derate 3°C (5.4°F) per 500 m
– or 2°C (3.6°F) per 1,000 ft – above sea
level.
Example:
At 1,600 m (1 mile) above sea level,
maximum ambient temperature should
not exceed 40.4°C (105°F). Cooler
temperatures are recommended, in
order to improve equipment reliability.
•
Do not install the VR-Link next to other
warm equipment.
2.1.4 Work Area
Provide a suitable work area with an
adequate table surface adjacent to the VR-
Link or host cabinet to permit bench
adjustment/repair.
2.2 PRE-INSTALLATION CHECKS
On delivery of the VR-Link, complete the
following:
NOTE
Pre-installation procedures do not require
technical knowledge of circuitry or their
operation to complete.
2.2.1 Accepting the Shipment
Inspect all shipments for transit damage
prior to acceptance.
2.2.2 Unpacking/Visual Inspection
Adhere to any warnings or instructions
posted on the shipping container. Packing
lists provide detailed listings of shipment
contents. Remove the VR-Link from the
shipping container and verify there is no
obvious damage.

NOTE
An ancillary kit (Nautel Part # 195-5195) is
provided with the VR-Link. Items from this kit
