► 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

► Gently insert the axis support and attach the switching axis (do not fix it yet).
Make sure that the two snap tabs of the axis support(1) can lock in place with the motor pro-
tection switch by slightly rotating the axis support (green arrow). The hole in the base of the
axis support(2) is now above a hole in the PKE switch.
NOTICE
The snap tabs break easily.
Proceed with caution as the snap tabs can break easily.
► Fix the axis support on the motor protection switch with the(3) screw supplied. Tighten the
screw with a torque of 0.5 to 1Nm. The screw is self-drilling.
► Adjust the position indicator on the axis. In the switched-off position, the arrow points to the
left if the setting screws of the PKZ are on top. Fix the position indicator with the screw(4).
Tighten the screw with a torque of 0.5 to 1Nm.
Fig.91: Fitting the switch bracket
► Fit the switch bracket(1) with the grub
screw(2). Tighten these with a torque
of 0.6Nm.
► Follow the removal instructions in reverse order for installation. Also observe the following
instructions:
– Set the nominal current and overcurrent (see below).
