 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.
