3.4.21 Replacing the motor protection switch PKE32/XTU-32
CAUTION
New version
Do not confuse this version of the motor protection switch with the old one. Pay particular
attention 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 tra-
verse forces against the axis coupling.
► This axis support can be retrofitted. For details, read the Technical Information "Retro-
fit Guide Axis Support Motor Circuit Breaker PKE32/XTU-32 Assembly 3p. (Main
Switch)" [DE: TI2013-07D10] [EN: TI2013-07E10].

In non-US versions, the motor protection
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.

► Unplug the electrical connections to the motor protection switch. You may want to mark the
positions of these connections to make clear assignment easier later on.
NOTICE
Orientation of the motor protection switch
In older machines, the motor protection switch is installed at an angle of 180°. In this case
the connectors 1 to T3 are located on top.
► Mark the position of the motor protection switch on the mounting rail.
► Lift the motor protection switch off the mounting rail.
Installation
► Remove the shunt release from the old motor protection switch and install it on the new one.
► Fit the new motor protection switch together with the shunt release on the mounting rail. Make
sure to position and align it correctly (observe the marking).
► Reestablish all electrical connections.
The clamping screws are fastened with a torque. The valid torque values are printed on the
packaging of the motor protection switch:
Flexible cable 1.5 - 4 mm² → 1.7 Nm

► Fit the two shaft support plates(1) on
the mounting rail. Make sure that the
gray clamping blocks engage with the
mounting rail.
