Intended use Scope of delivery
The universal measuring device PEM555 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 replace analogue indicating instruments. The PEM555 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 principally carried out using measuring current and voltage transformers.
The accuracy of the active energy metering corresponds to class
0.2 S in compliance with the DIN EN 62053-22 (VDE 0418 Part 3-
22):2003-11.

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.

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 distribution 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 connection type (TYPE) has to be set to delta connection (DELTA).
For this purpose, the measuring inputs L2 and
N are to be bridged.
The coupling via measuring current transformers allows the use of the measuring device in medium and high voltage systems.
The transformation ratio can be adjusted in
the PEM555 (1…2200).

Connection
1. Connect the device according the wiring diagram. The connections are located on the rear of the device. Connect the
PEM555 to the supply voltage (terminals A1 and A2
resp. +/-). Connect terminal " " to the protective conductor.

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.
