2. Safety
2.1 Intended use
The universal measuring device PEM575 is suitable for
 the analysis of energy and power
 monitoring of the power supply quality
 data recording for energy management.
As a compact device for front panel mounting, it is a replacement for analogue in-
dicating instruments. Das PEM575 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 con-
nected via external ../1 A or ../5 A measuring current transformers. In principle, mea-
surements in medium and high voltage systems are carried out via measurement
transformers and voltage transformers.
Use for the intended purpose also 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 de-
vice.
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 Ger-
many, 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.

Safety

2.3 General safety instructions
Bender devices are designed and built in accordance with the state of the art and
accepted rules in respect of technical safety. However, the use of such devices may
introduce risks to the life and limb of the user or third parties and/or result in dama-
ge to Bender equipment or other property.
 Only use Bender equipment:
– as intended
– in perfect working order
– in compliance with the accident prevention regulations and guidelines appli-
cable at the location of use
 Eliminate all faults immediately which may endanger safety.
 Do not make any unauthorised changes and only use replacement parts and opti-
onal accessories purchased from or recommended by the manufacturer of the
equipment. Failure to observe this requirement can result in fire, electric shock
and injury.
 Information plates must always be clearly legible. Replace damaged or illegible
plates immediately.
 If the device is overloaded by overvoltage or a short-circuit current load, it must
be checked and replaced if necessary.
 If the device is being used in a location outside the Federal Republic of Germany,
the applicable local standards and regulations must be complied with.
European standard EN 50110 can be used as a guide.
Danger of electric shock!
Touching live parts will cause danger of electric shock with fatal
consequences.
All work activities on electrical installations as well as installation
activities, commissioning activities and work activities with the device in
operation may only be carried out by electrically skilled persons!

Device description
18 PEM735_D00084_00_M_XXEN/02.2015
The accuracy of the active energy metering corresponds to class 0.2 S in compli-
ance with the DIN EN 62053-22 (VDE 0418 Part 3-22):2003-11.
The large display of the panel mounting device makes the relevant measured
quantities easily legible and enables fast configuration. In addition, the RS-485 in-
terface allows a central evaluation and processing of data. Switching operations
can be monitored or initiated via the digital inputs and outputs (Example: Swit-
ching off uncritical loads if the peak load limit value is exceeded).
The universal measuring device PEM575 provides the following functions:
 Provision of energy consumption data for a well-thought-out energy manage-
ment
 Allocation of energy costs
 Power quality monitoring for cost reduction and increased plant availability
 High-resolution waveform recording allow analysis of power quality phenomena
