Quick start
Intended use Scope of delivery
The universal measuring device PEM533 is suitable for
●the analysis of energy and power (Power Analyzer)
●monitoring of the power supply quality (Power Quality)
●data recording for energy management (Energy Manage-
ment).
As a compact device for front panel mounting, it is suitable to re-
place analogue indicating instruments. The PEM533 is suitable for
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
external ../1 A or ../5 A measuring current transformers.
Measurement in medium and high-voltage systems are principal-
ly carried out using measuring current and voltage transformers.
The accuracy of the active energy metering corresponds to class
0.5 S in compliance with the DIN EN 62053-22 (VDE 0418 Part 3-
22):2003-11.

Safety instruction
Danger of electric shock!
Follow the basic safety rules when working with electricity.
Consider the data on the rated voltage and supply voltage as
specified in the technical data!
Installing the device
Front-panel mounting (front view, side view, panel cutout)
A front-panel cutout of 92 mm x 92 mm is required for the device.
1. Insert the device into the installation opening of the front panel.
2. Insert the two installation clips into the equipment rail from behind.
3. Push the installation clips towards the front panel and tighten the screws by hand.
4. Check the device to ensure that it is firmly mounted in the front panel.

Connection of the device
Wiring diagram
Connection
1. Connect the device according the wiring diagram. The con-
nections are located on the rear of the device. Connect the
PEM533 to the supply voltage (terminals A1 and A2
resp. +/-). Connect terminal " " to the protective conduc-
tor.
2. Line protection: 6 A fuse recommended. If being supplied
from an IT system, both lines have to be protected by a fuse.
3. Connection to the RS-485 bus is made via the terminals D+,
D- and SH. Up to 32 devices can be connected to the bus.
The maximum cable length for the bus connection of all
devices is 1200 m.

Three-phase 4-wire system (TN, TT, IT
systems) Three-phase 3-wire system Connection via voltage transformers
The PEM can be used in three-phase 4-wire
systems, independent of the type of distribu-
tion system (TN, TT, IT system).
The PEM can be used in three-phase 3-wire
systems. The line conductor voltage must not
exceed AC 400 V.
When used in 3-wire systems, the con-
nection type (TYPE) has to be set to delta con-
nection (DELTA).
For this purpose, the measuring inputs L2 and
N are to be bridged.
The coupling via measuring current trans-
formers allows the use of the measuring de-
vice in medium and high voltage systems.
The transformation ratio can be adjusted in
the PEM533 (1…2200).

Commissioning of the device Start
Check proper connection
Observe the relevant standards and regulations that have to be ob-
served for installation and connection as well as the manual of the
respective device.
Before switching on
Before switching on think carefully about these questions:
1. Does the connected supply voltage US correspond to the
nameplates information?
2. Is the nominal system voltage of the measuring current
transformer not exceeded?
3. Does the measuring current transformer's maximum current
correspond to the nameplate information of the connected
device?
After switching on
After switching on, proceed as follows:
1. Connect the supply voltage.
2. Set the bus address/IP address.
3. Set the CT transformer ratio (for each channel).
4. Change the measuring current transformer's counting direc-
tion, if required.
5. Set the nominal voltage.
6. Select wye connection or delta connection.
Pressing the "ENERGY/OK" button enters the setup mode (> 3 s).
Pressing the "ENERGY/OK" again (> 3 s) returns to the display
mode.
A correct password must be entered before changes are allo-
wed. (factory setting: 0)
