Ventilation requirements: When installing the product in a
cabinet, the convection into and out of the product must not be
restricted. The ambient temperature (outside the cabinet) must be
less than the maximum operating temperature of the product by
4 °C for every 100 watts dissipated in the cabinet. If the total
power dissipated in the cabinet is greater than 800 watts, then
forced convection must be used.
Install the instrument so that the power switch is readily
identifiable and is easily reached by the operator. This is the
instrument disconnecting device. It disconnects the mains circuit
from the mains supply before other parts of the instrument.
Alternatively, an externally installed switch or circuit breaker
(which is readily identifiable and is easily reached by the
operator) may be used as a disconnecting device.
Always use the three-prong AC power cord supplied with this
instrument. Failure to ensure adequate earth grounding by not
using this cord may cause instrument damage.
This instrument has autoranging line voltage input. Be sure the
supply voltage is within the specified range.
