Short instructions
Intended use
The digital universal measuring device PEM330/PEM333 is suitable
for measuring and displaying electrical parameters of electricity
networks. The device measures current, voltage, energy consumpti-
on and power as well as the total harmonic distortion for assess-
ment of the voltage and current quality.
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.

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 cut-out)
A front panel cutout of 92 mm x 92 mm is required for the device.
1. Fit the device through the cut-out in the front panel.
2. Put the 4 transparent mounting brackets from behind on the edges of the device.
3. Push the clips tightly against the panel to secure the device.
4. Check the device to ensure that it is firmly installed in the front panel.

Connection of the device
Wiring diagram
Connection
1. The connecting terminals are located on the rear. Connect
the PEM330/PEM333 to the supply voltage (terminals A1 and
A2 resp. +/-). Connect terminal " " to the protective con-
ductor.
2. Power protection by a 6 A fuse, quick response. If being sup-
plied 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.
Connection diagram voltage inputs
Three-phase 4-wire system (TN, TT, IT systems)
The PEM can be used in three-phase 4-wire systems, independent of
the type of distribution system (TN, TT, IT system).
Three-phase 3-wire system
The PEM can be used in three-phase 3-wire systems.
The line-to-line voltage must not exceed AC 400 V.
Connection via voltage transformers
The coupling via measuring voltage transformers allows the use of
a measuring device in medium and high voltage systems. The trans-
formation ratio in PEM330/PEM333 can be adjusted (1…2200).

Commissioning
Check proper connection
During installation and connection, abide by the relevant standards
and regulations and follow the operating manuals for the device.
Before switching on
1. Before switching on think carefully about these questions:
2. Does the connected supply voltage US correspond to the
nameplates information?
3. Is the nominal system voltage of the measuring current
transformer not exceeded?
4. Does the measuring current transformer's maximum current
correspond to the nameplate information of the connected
device?
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.
