2.2.2.3 Configuration of option slots on the connection level
The connection level of the field distribution frequency inverter is divided into 2 areas.
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).
Area 1, option slots X1 to X3
Typical machinery plug connectors are used. These are primarily used to connect the mains and the
motor cables. Certain plug connector versions also allow connection of a 24 V DC supply. The plug
connectors are equipped with a detachable protective cap. The mating plug connector is not
included in the scope of supply.
