Safety and Regulatory Information
Before Applying Power
Verify that the premises electrical supply is within the range of the instrument. The instrument
has an autoranging power supply.
If this product is not used as specified, the protection provided by the equipment
could be impaired. This product must be used in a normal condition (in which all
means for protection are intact) only.
The Mains wiring and connectors shall be compatible with the connector used in
the premise electrical system. Failure, to ensure adequate earth grounding by not
using the correct components may cause product damage, and serious injury.
Before switching on this instrument, make sure the supply voltage is in
the specified range.
Verify that the premise electrical voltage supply is within the range specified
on the instrument.
Ventilation Requirements: When installing the instrument in a cabinet, the
convection into and out of the instrument must not be restricted. The
ambient temperature (outside the cabinet) must be less than the maximum
operating temperature of the instrument by 4 °C for every 100 watts
dissipated in the cabinet. If the total power dissipated in the cabinet is
greater than 800 watts, forced convection must be used.
Always use the three-prong AC power cord supplied with this product. Failure to
ensure adequate earth grounding by not using this cord may cause product
damage and the risk of electrical shock.
This product is designed for use in Installation Category II and Pollution Degree 2.
This instrument has auto-ranging line voltage input. Be sure the supply
voltage is within the specified range and voltage fluctuations do not
exceed 10 percent of the nominal supply voltage.
