Power Quality Logger

Safety Instructions

W X 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.
