B 3.2 Electrical connections
The system must be wired according to the accompanying
connection diagram or plugged into the appropriate cable sockets.
Standard wiring sleeves with collars (DIN 46228/Part 4) must be
used with all cable connections up to 0.75 mm².
Wiring sleeves must not be used with cables from 0.75 mm² up to a
maximum of 1.5 mm².
Using wiring sleeves:
The spring-loaded terminals have been optimised for square
crimping. This can be realised using, for example, ‘WAGO’ vario-
crimp pliers.
This type of crimping also enables the connection to be connected
and disconnected without any problems.
The crimping is also gas-tight, i.e. there is no space inbetween the
conductor and the wiring sleeve.
Using cable without wiring sleeves:
For fine and multi-core cable and for fine-wired cable, whose kink
resistance is not sufficient due to its small diameter, in order to
overcome the contact force of the clamping springs, the clamp must
be correctly opened using a screwdriver.
Check that all the cables are fitted tightly after the connections have
been made (in both cases).
The ekrPro Com
60
controller is protected against incorrect
connection.
If the supply voltage was inversely connected to terminals 42
and 43 of the controller, this inverse polarity would also be
connected to the 24 V output socket.
This could lead to damage to components connected to this
socket.
Attention! Applications with a sensor adjustment unit!
The stepping motor output stages are not
protected against
short circuits.
You must check, without fail, using a suitable test unit
(ohmmeter) that no short circuits or cross-connections
between the two windings exist before starting the
commissioning.
