Warnings
•
To avoid electrical shock, do not connect any part of
the Logger to systems that have higher voltages to
ground (earth) than are marked on the Logger.
•
Areas between the power company meter and the
source of the distribution system are characterized as
CAT IV areas. To avoid electrical shock or equipment
damage, never connect the Logger to power in CAT IV
areas if the voltage-to-earth ground is greater than
300 V.
•
To avoid damaging the Logger, never connect its
voltage measuring inputs to phase-to-phase voltages
higher than 830 V.
•
To avoid damaging the Logger, never connect the
power supply leads to voltages higher than 660 V RMS
ac.
•
The Logger is to be used and handled only by qualified
personnel (see page 6).
•
Maintenance work on the Logger must be done only by
qualified service personnel.
•
Use only the current probes specified in this manual. If
you use flexible current probes, wear suitable
protective gloves or work on de-energized conductors.
•
Do not expose the Logger to moisture or humidity.
•
To prevent electrical shock, always connect power
supply and voltage test leads to the Logger before
connecting to the load.
•
All accessories must be approved for 600 V CAT III or
higher.
•
Use the Logger only with its original standard
equipment or with approved optional accessories, as
listed in Table 2 and Table 3 in this manual.
