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].
