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.
