206 FieldFox User’s Guide
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 clean internally.
When the FieldFox 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 FieldFox 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.
To avoid overheating, always disconnect the FieldFox from the AC/DC
adapter before storing the FieldFox in the backpack.
If you prefer to leave the FieldFox connected to the AC/DC adapter while
inside the backpack, you can disconnect the AC/DC adapter from its AC
power source to prevent overheating.
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 Second Edition and 664.
For the External Battery Charger (N9910X–872)
If charging batteries externally, use the optional external charger available from
Agilent, or another SMBus charger of level II or higher.
Never use a non–SMBus charger because the battery issues commands over
the SMBus to the charger to control the charge rate and voltage.
Never use a modified or damaged charger.
For the Battery
Lithium battery packs may get hot, explode, or ignite and cause serious injury if
exposed to abuse conditions. Be sure to follow these safety warnings:
