Placement and Rack Mounting
Put the 5730A Calibrator on top of a bench or mount in a standard-width, 24-inch
(61-cm) deep equipment rack. For bench-top use, the Calibrator has non-slipping,
non-marring feet. To mount the Calibrator in an equipment rack, use the Rack Mount
Kit (Model Y5737) or the Rack Ear Kit (Model Y5738). Instructions are included
with the kit.
 Warnings
To prevent possible electrical shock, fire, or personal injury, do
not restrict access to the Calibrator mains power cord. The
mains power cord is the mains disconnecting device. If access
to the power cord is inhibited by rack mounting, a properly-
rated accessible mains disconnecting switch must be provided
within reach as part of the installation.
Cooling Considerations
 Caution
Damage caused by overheating can occur if the area around the
air intake is restricted, the intake air is too warm, or the air filter
becomes clogged.
Adhere to these rules to lengthen the life of the 5730A Calibrator and enhance its
performance:
•
The area around the air filter must be at least 3 inches from nearby walls or rack
enclosures.
•
The exhaust perforations on the sides of the Calibrator must be clear of obstructions.
•
The air that enters the Calibrator must be room temperature. Make sure that exhaust
from another instrument is not directed into the fan inlet.
•
Clean the air filter every 30 days or more frequently if the Calibrator is operated in a
dusty environment. Instructions for cleaning the air filter are in Chapter 7.
Mains Voltage Selection
The 5730A Calibrator automatically detects the main line voltage when the soft power
switch is pushed and configures itself to work at that voltage level. Nominal mains
voltages ranging from 100 Vrms -120 Vrms and from 220 Vrms -240 Vrms (
±
10 %) are
acceptable, with frequencies from 47 Hz to 63 Hz.
