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..." [}16].
► Before you start working, check the power supply for absence of voltage and observe the
waiting times!
► Use a suitable screwdriver to turn the fuse holder out of its socket.
► Remove the old microfuse from the fuse holder and replace this with a new microfuse of the
same type.
Installation
► Follow the removal instructions in reverse order for installation.
3.4.17 Replacing the main switch 3LD2
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].

Removal
► Switch off the machine, disconnect it from the power supply and secure it to prevent
unauthorized reactivation.
1.2 "Preparatory work..." [}16]
► Before you start working, check the power supply for absence of voltage and observe the
waiting times!
► Unplug all connections to the main switch. You might like to mark their positions to make clear
assignment easier later on.
► Dismantle the shafton the main switchby pressing this together at the sides and pulling it off.
You will need to use this again on the new switch. This is reused on the new switch.
► Open the lock on the rail and remove the main switch. You may need to read the manufac-
turer's instructions provided.
Installation
► Follow the removal instructions in reverse order for installation. Also observe the following
instructions:
●
Fit the shaft from the old switch onto the new switch.
