1.2 Modular Inverters
1 – 2
On the UM 1xx modular inverters, HEIDENHAIN is using new 4-pin socket
connectors for connection of the motor holding brake (X392). The mechanical
change of this new socket connector makes it possible to do without the cable
ties previously needed for strain relief of the lines for the holding brake (X392).
In the transition to the new socket, new 4-pin connectors (ID 646 182-02) are
provided in the accessories with the inverters. Connection specifications of
the new connector with spring terminals:
Line diameter for frequent flexing min.
Line diameter for frequent flexing max.
Line diameter for rigid configuration min.
Line diameter for rigid configuration max.

Together with the new connectors, eyelets are being introduced on the UM
1xx modular inverters. These eyelets make it easier to fasten the cable ties for
strain relief that are still required for the 24 V power supply for the motor
holding brake (X344). Units with these changes are indicated by the index. The
index is on the ID label of the unit after the serial number.
