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.
Always use the Source Module Interface (DC bias) 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.
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.
This instrument has auto-ranging line voltage input; be sure the supply voltage is
within the specified range and that voltage fluctuations do not exceed 10 percent of
the nominal supply voltage.

Servicing
These servicing instructions are for use by qualified personnel only. To avoid electrical
shock, do not perform any servicing unless you are qualified to do so.
These servicing instructions are for use by qualified personnel only. To avoid electrical
shock, do not perform any servicing unless you are qualified to do so.
The opening of covers or removal of parts is likely to expose the user to dangerous
voltages. Disconnect the instrument from all voltage sources before opening.
No operator serviceable parts inside. Refer servicing to qualified personnel. To prevent
electrical shock, do not remove covers.
The detachable power cord is the instrument disconnecting device. It disconnects
the mains circuits 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.
Connector Care and Cleaning Precautions
Remove the power cord to the instrument. To clean the connectors use alcohol in a well
ventilated area. Allow all residual alcohol moisture to evaporate, and fumes to dissipate prior to
energizing the instrument.
To prevent electrical shock, disconnect the E8257DS02-S15 from mains electrical
supply before cleaning. Use a dry cloth or one slightly dampened with water to clean the
external case parts. Do not attempt to clean internally.
If flammable cleaning materials are used, the material shall not be stored, or left open in
the area of the equipment. Adequate ventilation shall be assured to prevent the
combustion of fumes, or vapors.

Safety and Regulatory Information
Electrostatic Discharge Protection
Protection against electrostatic discharge (ESD is essential while removing assemblies from or
connecting cables to the instrument. Static electricity can build up on your body and can easily
damage sensitive internal circuit elements when discharged. Static discharges too small to be
felt can cause permanent damage. To prevent damage to the instrument:
•always have a grounded, conductive table mat in front of your test equipment.
•always wear a grounded wrist strap with grounding cord, connected to a grounded
conductive table mat, having a 1 M resistor in series with it, when handling components
and assemblies or when making connections.
•always wear a heel strap (9300-1126) when working in an area with a conductive floor. If you
are uncertain about the conductivity of your floor, wear a heel strap.
•always ground yourself before you clean, inspect, or make a connection to a static-sensitive
device or test port. You can, for example, grasp the grounded outer shell of the test port or
cable connector briefly.
•always ground the center conductor of a test cable before making a connection to the
instrument test port or other static-sensitive device. This can be done as follows:
1. Connect a short to one end of the cable to short the center conductor to the outer
conductor.
2. While wearing a grounded wrist strap, grasp the outer shell of the cable connector.
3. Connect the other end of the cable to the test port and remove the short from the cable.
