Parts, Equipment and Tools
If you have supply voltages of 3x208 V~ and 3x230 V~, you will need to use the motor protection tripping
unit ZM-32-PKZ2 [00342496-xx].
▪ Motor protection tripping unit ZM-16-PKZ2 [00342495-xx] (default)
▪ Motor protection tripping unit ZM-32-PKZ2 [00342496-xx] (US version)
Overview
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..." [ ➙ 12].

Overview
CAUTION
New version
Do not confuse this version of the motor circuit breaker 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 motor circuit breaker.
When inserting the door coupling handle onto the extension axis of the motor circuit breaker,
the axis could move into a slanted position. In this case, high traverse forces will be exerted
against the axis coupling of the motor circuit breaker, 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 motor circuit breaker. This sup-
port is used to limit the slant of the extension axis and therefore to reduce the traverse forces
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].
Motor circuit breaker and main switch (using example of
US version)
1. Motor circuit breaker
2. Main switch (US version only)
In non-US versions, the motor circuit breaker also serves
as the main switch.
