2. Safety
2.1 Intended use
The universal measuring device PEM735 is suitable for
 
the analysis of energy and power (Power Analyser)
 
monitoring of the power supply quality (Power Quality)
 
data recording for energy management (Energy Management).
As a compact device for front panel mounting, it is suitable to replace analogue indicat-
ing instruments. PEM735 is suitable for 2, 3 and 4-wire systems and can be used in TN,
TT and IT systems. The current measurement inputs of the PEM are connected via exter-
nal …/1 A or …/5 A measuring current transformers. In principle, measurements in me-
dium- and high-voltage systems are carried out via measuring current and voltage
transformers.
Use for the intended purpose includes:
 
Device-specific settings according to local equipment and operating conditions.
 
The observation of all information in the operating manual.
2.2 Qualified personnel
Only electrically skilled persons are authorised to install and commission this device.
Electrically skilled persons are those who have the relevant education, knowledge and
experience, as well as knowledge of the relevant safety standards and who are able to
perceive risks and to avoid hazards which electricity can create when work activities are
carried out on electrical installations. The electrically skilled person is specially trained
for carrying out work activities in his specific working environment and has a thorough
knowledge of the relevant standards and regulations. In Germany, an electrically skilled
person must meet the requirements of the accident prevention regulation BGV A3. In
other countries the applicable regulations have to be observed and followed.
