7.2.1 Plug connection

CAUTION! Risk of damage to property!
Improperly connecting the plug can lead to contact problems and electrical damage.
• The plug must be screwed into its end position via the fastening screw so that the
module and plug surface are flush.
• To avoid damage due to water ingress in the electronics, the sealing elements must
not be pressed out of the unused threaded cable connections.
For the electrical connection, the plug must be disconnected from the control module
(fig. 4a).
• Loosen the fastening screw of the plug using a Torx or slotted screwdriver (fig. 4a,
item 1). The plug moves itself out of its holding position.
Carefully pull out the plug.
• Screw off both threaded cable connections (fig. 4b) and carefully remove the top part
of the plug.
• Press the sealing elements of the threaded cable connection out using a screwdriver
(fig. 4c, item 1).
NOTE: A sealing element which has been removed by mistake must be pressed back into
the threaded cable connection!
• Prepare a cable (provided on-site) for the mains and SSM connection in acc. with fig. 4c/
4d.
• Establish the mains and, if applicable, SSM connection according to the terminal desig-
nations and place the cable in the bottom section of the plug (fig. 4e/4f).
• Engage the top section of the plug, hinge bars first, into the hinge openings of the bot-
tom section and fold shut (fig. 4g). Screw on threaded cable connections.
• Place the plug at the plug-in position of the control module and screw on using a Torx
or slotted screwdriver (fig. 4h, item 1). The plug is joined in its end position as it is
screwed into place.
NOTE: The module and plug surfaces must be flush.
The maximum contact load is achieved when the plug is in its end position.

7.2.2 Allocation of the threaded cable connections

The following table shows the possible combinations of electric circuits in a cable for
assigning the individual threaded cable connections. DIN EN 60204-1 (VDE 0113, sheet 1)
must be complied with:
• Clause 14.1.3 as follows: Conductors of different electric circuits may belong to the
same multi-conductor cable if the highest voltage which may occur in the cable is insu-
lated sufficiently.
• Clause 4.4.2 as follows: Signal lines with low levels should be separated from power lines
if there is a potential risk of functional interference due to EMC.
