RMC-8356 Installation Guide
This equipment contains voltage hazardous to human life and safety, and is capable of inflicting
personal injury.
•
Chassis Grounding
—The RMC-8356 requires a connection from the premise wire safety
ground to the RMC-8356 chassis ground. The earth safety ground
must
be connected during
use of this equipment to minimize shock hazards. Refer to the
section for instructions on connecting safety ground.
•
Mechanical Loading
—To avoid a hazardous load condition, be sure the mechanical load
is even when rack mounting the equipment.
•
Live Circuits
—Operating personnel and service personnel must
not
remove protective
covers when operating or servicing the RMC-8356. Adjustments and service to internal
components must be undertaken by qualified service technicians. During service of
this product, the mains connector to the premise wiring must be disconnected. Dangerous
voltages may be present under certain conditions; use extreme caution.
•
Explosive Atmosphere
—Do
not
operate the chassis in conditions where flammable gases
are present. Under such conditions, this equipment is unsafe and may ignite the gases or gas
fumes.
•
Parts Replacement
—Service this equipment only with parts that are exact replacements,
both electrically and mechanically. Contact National Instruments for replacement part
information. Installation of parts with those that are not direct replacements may cause
harm to personnel operating the chassis. Furthermore, damage or fire may occur if
replacement parts are unsuitable.
•
Modification
—Do
not
modify any part of the RMC-8356 from its original condition.
Unsuitable modifications may result in safety hazards.
Chassis Cooling Considerations
The RMC-8356 is designed to operate on a bench or in an instrument rack. Determine how you
want to use the RMC-8356 and follow the appropriate installation instructions.
Caution
If installed in a closed or multiunit rack assembly, the rack environment
operating ambient temperature may be greater than room ambient temperature.
Therefore, install the equipment in an environment compatible with the maximum
ambient operating temperature (Tma) specified in Appendix A,
Specifications
, in the
RMC-8356 User Manual
.
Providing Adequate Clearance
Apertures in the front and rear of the chassis facilitate power supply and motherboard cooling.
Air enters through the front of the chassis and exits through the fans on the rear of the chassis.
Place the RMC-8356 on a bench top or in an instrument rack so that the fans (air outlets) and the
air inlet apertures in the front and rear of the chassis have adequate ventilation. Keep other
equipment a minimum of 76.2 mm (3 in.) away from the air outlets on the rear of the chassis.
