PEM735-measuring_case_D00240_00_M_XXEN/12.2015
1. Function and safety
The PEM735 measuring and demonstration case is used for
mobile measurements to analyse the voltage quality accord-
ing to DIN EN 50160 (measurement according to IEC 61000-
4-30 class A).
For the use of this measuring case, specialist knowledge is
required.
It is essential to follow the existing safety regulations!
About this manual
In the schematic presentation, the elements belonging to the Rogowski coils are de-
picted in pink and all elements belonging to the AUX transformers are depicted in
green.
Risk of fatal injury from electric shock!
Incorrect wiring of the measuring voltage cables may cause a short-circuit
of the installation, arcs and high short-circuit currents.
The secured side of the measuring voltage cable (longer plug) must be
connected to the installation!
Risk of fatal injury from electric shock!
AUX transformers may not be operated as an
open circuit on the secondary side!
Connected AUX transformers must be short-
circuited with a jumper wire when not in use!

3. Connecting the measuring case
For your safety, consider the sequence of the work steps:
1. Configure measuring case mechanically (insert jumper wires for the trans-
formers used, adjust transducers for Rogowski coils)
2. Install measuring current transformer
3. Commission measuring case
4. Configure PEM735
5. Install measuring voltage cables
The measuring case is operated with 230 V, 50 Hz. The connecting cable is included.
