Safety Considerations
For the AC/DC Adapter
For the AC/DC Adapter
Use only the designated AC/DC adapter supplied with the
instrument.
Use only the designated power cord supplied with the AC/DC
adapter.
Operated at an ambient temperature: 0 to 40°C; full power rating;
derate linearly to 50 W at 50°C.
Maximum output rating: +15V/4.0 A.
Input rating: AC 100–250 V, 50/60Hz
Main Plug: Use a 3–pin main plug that complies with IEC 60884–1,
Plugs and Socket–Outlets for Household and Similar Purposes –
Parts1: General Requirements and country specific safety authority
requirements, such as UL, SA, BSI, VDE, CCC, SA, NZ, and PSE.
Appliance Connector: Use an appliance connector certified to IEC
60320–1/EN 60320–1 requirements
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.
