Overview
CAUTION
New version
Do not confuse this version of the protective motor switch with the old one. Pay particular at-
tention to the settings.
NOTICE
Missing axis support
The machine is switched on with the help of an extension axis via the protective motor switch.
When inserting the door coupling handle onto the extension axis of the protective motor switch,
the axis could move into a slanted position. In this case, high traverse forces will be exerted
against the axis coupling of the protective motor switch, which could then break. This would
then make it impossible to switch the machine on or off.
Some machines do not have this additional axis support on the protective motor switch. This
support is used to limit the slant of the extension axis and therefore to reduce the traverse forc-
es against the axis coupling.
► This axis support can be retrofitted. For details, read the Technical Information "Retrofit
Guide Axis Support Motor Circuit Breaker PKE32/XTU-32 Assembly 3p. (Main Switch)"
[DE: TI2013-07D10] [EN: TI2013-07E10].
Protective motor switch and main switch (using example
of US version for the X-Series)
1. Protective motor switch
2. Main switch (US version only)
In non-US versions, the protective motor switch also
serves as the main switch.

Removal
► Switch off the machine, disconnect it from the power supply and secure it to prevent unauthorized
reactivation. Observe the instructions in section "1.2 Preparatory Work..." [ ➙ 13].
Checking the Power Supply for Absence of Voltage
► Before you start working, check the power supply for absence of voltage and observe the waiting
times!
Shaft support, fitted (example of SX1)
► Remove the fastening screw (1) on the shaft support.
Shaft support, remove (example of SX1)
► Remove the two shaft support plates (1) from the DIN
rail. The plates are locked in place on the DIN rail with
gray clamping blocks.
Switch bracket
► Loosen the grub screw (2) at the switch bracket (1)
and pull the switch bracket off.
