1. Use a screwdriver to retract all the orange
retaining clips from the instrument base until they
click into place.
2. Place the instrument over the DIN top hat rail.
If the optional DIN rail bus connector is used to
connect the FRAKO Starkstrombus and the
Display bus for several devices, ensure that the
pin strip in the base of the casing is correctly
inserted in the socket strip on the DIN rail bus
connector.
3. Press the orange retaining clips back into the
casing until they click audibly into place flush with
the edge of the instrument base.
Figure 4: Retracting the retaining clips
CAUTION!
A DIN rail bus connector may only be connected to the DIN rail bus connectors of other FRAKO
devices.
Connection to other types of DIN rail bus connectors from other manufacturers can damage or
destroy the EM-PQ 2300 and any connected devices not from FRAKO. The risk of fire can also not
be excluded.
It is therefore not permitted to connect with other types of DIN rail bus connectors from other
manufacturers.
5. Installation
Prerequisite: the instrument has been correctly fitted to the DIN rail as described in
Section 4, Mounting the
instrument, page 11
.
If the cabling is not EMC-compliant, it is possible that Class A emission limits (industrial environment radiation)
may be exceeded. However, when high quality EMC-compliant connecting cables are used and the instrument is
installed in a metal cabinet or a shielded enclosure, it can be reasonably assumed that the emission limits of
EN 55011/22 Class B (office and residential area) will be complied with.
In cases of interference from the supply network, we recommend installing a broadband filter in the line to the
instrument.
We recommend keeping cable lengths as short as possible and using shielded cables or possibly absorber
cables.
It can happen that the EMC emission limits are exceeded if the EM-PQ 2300 is used in combination with other
devices.
5.1 Electrical connections
The instrument is connected as shown in
Figure 5 and Figure 6, page 14
