CAUTION. Operating the instrument on an incorrect line voltage can cause
damage, possibly voiding the warranty. To avoid this, operate the instrument
with the correct line voltage.
The instrument operates from a single-phase line voltage listed in the following
table. Line voltage and line frequency are automatically sensed; there are no
switches to set. Check to ensure the operating voltage in your area is compatible.

with grounded outlets. When proper connections are made, the instrument chassis
is connected to power line ground through the ground wire in the power cord
providing protection against electric shock.
Ventilation
The unit has fans in the rear, as well as cooling vents on the bottom and side
panels to keep it from overheating.
CAUTION. Inadequate ventilation can damage the instrument; to avoid damaging
the instrument, observe the following precautions:
Do not block the c ooling vents.
Do not position any devices adjacent to the instrument that force air (heated or
unheated) into or onto the instrument surfaces or cooling vents. This additional
irflow could compromise performance.
a
When rack mounting the instrument, ensure there is adequate airflow around the
instrument rear, sides, and bottom to ensure proper cooling. Adequate airflow
enables air temperatures within approximately one inch of the instrument surfaces
to remain within specified limits under all operating conditions.

NOTE. Note: The generator is internally tem perature compensated for timing and
output level continuously and automatically. Internal timing calibration will also
take place whenever the frequency is set (either manually or through remote
programming). Setting the frequency (or resetting the frequency to its current
value) is recommended after an initial 20-minute warm-up, or if a significant
change in ambient temperature has occurred during operation.
