Fluke Data Acquisition System/Data Logging System 2680A Getting Started Manual page 5

Use the proper fuse. To avoid fire hazard, for fuse
replacement use only a 1/2 ampere, 250 V time delay line
fuse.
DC POWER SOURCE
The device may also be operated from a 9 V to 45 V dc power source when either
the rear panel ground binding post or the power cord grounding conductor is
connected properly. The input is protected by a 4 ampere fuse internal to the
device. This fuse should only be replaced by a qualified Fluke technician.
GROUNDING THE DEVICE
The device utilizes controlled overvoltage techniques that require the device to be
grounded whenever normal mode or common mode ac voltages or transient
voltages may occur. The enclosure must be grounded through the grounding
conductor of the power cord, or if operated on battery with the power cord
unplugged, through the rear panel ground binding post.
USE THE PROPER POWER CORD
Use only the power cord and connector appropriate for the voltage and plug
configuration in your country.
Use only a power cord that is in good condition.
Refer power cord and connector changes to qualified service personnel.
To avoid possible electric shock or damage to the device:
Read manual before operating.
Do not position device so that air flow through side
vents is restricted.
Do not use in a manner not specified in this manual or
safety protection may be impaired.
Disconnect power cord and ALL other inputs before
replacing a fuse.
Position the device where power cord can be
disconnected.
Do not exceed maximum voltages.
