2.3 Intended use
The PEM735 power quality analyser is intended for
 
analysing energy and power (Power Analyser)
 
monitoring the power supply quality (Power Quality)
 
recording relevant data for energy management (Energy Management).
As a compact device for front panel mounting it is suitable for replacing analogue indi-
cating instruments. The PEM735 can be used in three-phase 4-wire systems, three-
phase 3-wire systems and in TN, TT and IT systems (see "Connection diagram voltage in-
puts" on page 24 ff). The current measurement inputs of the PEM are connected via ex-
ternal …/1 A or …/5 A measuring current transformers. In principle, measurements in
medium and high-voltage systems are carried out via measuring current and voltage
transformers.
Use for the intended purpose includes:
 
Device-specific settings according to the installation and operating conditions on
site.
 
The observation of all information in the operating manual.
Any other use than that described in this manual is regarded as improper.
Although great care has been taken in the drafting of this operating manual, it may nev-
ertheless contain errors and mistakes. Bender cannot accept any liability for injury to
persons or damage to property resulting from errors or mistakes in this operating man-
ual.
