• Disconnect the power supply before connecting the motor to or disconnecting it
from the power supply.
• If the line-side connection is not connected to a motor, the power supply must
be disconnected. Otherwise, the contacts carry voltage and fatal injuries may
occur.
• Keep the male and female connectors dry and clean. This applies in particular
after disconnecting the connection.
• Any damaged connectors must be replaced without delay.
• Do not allow connector cables to fall into materials, chips, waste, etc. Danger of
damage to the connector cable!
Demag has developed a plug-and-socket connection for KB. sliding rotor motors
and Z.. cylindrical rotor motors by means of which the corresponding motors can
be connected and disconnected within a very short time. Work-intensive individual
wiring in the terminal box is no longer necessary, a purely mechanical activity is
required only. The design eliminates connection errors and thus ensures safety of
the process.
These advantages are particularly significant for work to be carried out in an ergo-
nomically unfavourable position and at large heights.
Since maintenance work is also involved in addition to installation and repair work, a
large amount of hours worked and costs incurred must be assumed, in particular in
larger installations. Long-term malfunctions, for example, which might result in inter-
rupting the production process can therefore be avoided with this fast method. In
addition, the installation time and thus the overall costs of an installation are re-
duced. Inserts with a different number of poles can be used inside the new connec-
tor housing. This concept can also be integrated on an international level, since
Demag always incorporates standardized, commercially available plug inserts of the
Harting type.
The system is available as an option for the motor ranges of sizes 63 to 132. Al-
though the extra engineering is reflected in a higher price, the customer is provided
with a more economical solution that is the result of later savings for maintenance
and repairs. Various industry sectors, such as the automotive industry, have recog-
nized this benefit and already request this connector.
In the following, mounting of the plug-and-socket connection to Demag ZBF travel
motors is described.
All existing operating instructions continue to be valid also for motors with plug-and-
socket connection.

• All connectors are assembledaccording to the connector identification when the
crane set is assembled.
• Connection to the power supply is made to the terminals of the isolator switch in
the crane bridge enclosure.
