Regulatory Information
To prevent electrical shock, disconnect the AC to DC adapter from the
mains before cleaning. Use a dry cloth or one slightly dampened with
water to clean the external case parts. Do not attempt to cleans internally.
When the is connected to the AC/DC adapter, position the adapter so the
power cord is readily accessible. The power cord is the disconnecting
device. It removes main power to the AC/DC adapter. The front panel
switch is only for the DC power within the instrument, and not for the
AC/DC adapter. Alternately, an AC switch or circuit breaker (which is
readily identifiable and is easily reached by the operator) may be installed
and used as a disconnecting device to remove mains power from the
AC/DC adapter.
The AC/DC adapter has an auto–ranging line voltage input – be sure the
supply voltage is within the specified range.
The AC/DC adapter is for indoor use only.
Never use a modified or damaged charger. Use the original AC–DC
adapter ONLY.
The AC/DC adapter is designed for use in Installation Category II and
Pollution Degree 2 per IEC 61010-1.
