2.2 Installation
2.2.1 General precautions for installation
Note the following precautions to prevent damage to the
FRA5014
.
•
The
FRA5014
uses a fan for forced-air cooling. Air intake occurs via the bottom front
panel of the unit and air exhaust occurs via the central rear panel. Do not obstruct
either the air intake or exhaust areas.
•
If the
FRA5014
is used with its rear panel facing downward (installed vertically), it
may topple easily. Always install it horizontally (with its bottom facing the floor).
◼
Handling of panels and case
The
FRA5014
’s front panel is made of plastic. Be careful to prevent damage that may be
caused by sharp objects or high temperatures.
When the panel or case surfaces become dirty, use a soft cloth to wipe them. For stubborn dirt,
dip the cloth in a neutral detergent and wring it out well before wiping off the dirt . Avoid use
of organic solvents such as paint thinner or benzene, or pre-moistened wipes, as they may cause
discoloration, clouding, and/or peeling of the surface coating.
2.2.2 Installation conditions

Do not install the FRA5014 in the following locations:
•
Location exposed to direct sunlight or near a heat source
•
Locations where dust, salt, and/or metallic powder is prevalent
•
Locations where corrosive gas, steam, and/or oily smoke is prevalent
•
Location exposed to excessive vibration
•
Within or close to sources of strong magnetic fields
•
Close to sources of pulsing noise.
When measurement precision is important, warm up the FRA5014 at least two hours before using
it, then run self calibration before starting measurements. If the ambient temperature has
changed more than 5 °C, or if the FRA5014 has been used continuously for more than 24 hours,
running self calibration again is recommended.
Keep the mains supply cord separated from the signal cable. If the mains supply cord and signal
cable get too close, operation faults or noise may lead to inaccurate measurements.
