2.2.2.4 Configuration of the option slot for the maintenance switch level
DANGER Electric shock at X2
An optional mains connection outlet (LA) on option slot X2 can also not be switched off with a repair and
maintenance switch (option slot H3). This may therefore still be at mains voltage.
• Do not touch any contacts.
• Disconnect the device from the mains (mains supply, option slot X1).
Option slot H3 is intended for equipment with an optional repair and maintenance switch. Various
versions (e.g. lockable/non-lockable) may be installed.
The repair and maintenance switch disconnects the supply to the device and therefore also the supply
to the directly connected motor. For device versions which are intended for passing through the mains
voltage, the daisy chain channel is not interrupted. The following devices are still supplied.
