2. Safety
2. 1 Intended use
The universal measuring device PEM330/PEM333 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 ana-
logue indicating instruments. The PEM330/PEM333 is suitable for 2, 3 and 4-
wire systems and can be used in TN, TT and IT systems. The current measure-
ment inputs of the PEM are connected via external …/1 A or …/5 A measuring
current transformers. In principle, measurements in medium and high voltage
systems are carried out via measurement transformers and voltage transform-
ers.
Use for the intended purpose also includes:
 Device-specific settings compliant with 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, knowl-
edge 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 elec-
trically 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.

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 de-
vices may introduce risks to the life and limb of the user or third parties and/
or result in damage to Bender equipment or other property.
 Only use Bender equipment:
– as intended
– in perfect working order
– in compliance with the accident prevention regulations and guide-
lines applicable 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 optional accessories purchased from or recommended by
the manufacturer of the equipment. Failure to observe this require-
ment 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 com-
plied 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!

3.5 Description of function
The digital universal measuring device PEM330/PEM333… is suitable for
measuring and displaying electrical parameters of electricity networks. The
device measures current, voltage, energy consumption and power as well as
the total harmonic distortion for assessment of the voltage and current qual-
ity.
The accuracy of the active energy metering corresponds to class 0,5 S in com-
pliance with the DIN EN 62053-22 (VDE 0418 Part 3-22):2003-11. The current
measurement inputs of the PEM are connected via external …/1 A or …/5 A
measuring current transformers.
The large display of the panel mounting device makes the relevant measured
quantities easily legible and enables fast configuration. In addition, the RS-
485 interface* allows a central evaluation and processing of data. Switching
operations can be monitored or initiated via the digital inputs and outputs
(Example: Switching off uncritical loads if the peak load limit value is
exceeded).
The universal measuring device PEM330/PEM333 provides the following
functions:
 Provision of energy consumption data for a well-thought-out energy
management
 Allocation of energy costs
 Power quality monitoring for cost reduction and increased plant
availability
