2.9 Plug connectors
The use of optionally available plug connectors for power and control connections not only makes it possible
to replace the drive unit more quickly in case of servicing, but also minimises the danger of installation
errors when connecting the device. The most common plug connector versions are summarized below.
The possible mounting locations on the housing box are listed in Section 2.1.4.
2.9.1 Plug connectors for power connections
Plug connectors for the motor or mains connection to the frequency inverter are available.
Connection of up to two power plug connectors (HAN Q4-2: up to 2 x 2 plug connectors) are made on the
housing of the frequency inverter. The following 3 connection versions are available:
Mounting version Meaning
… - LE Power input
… - LA Power output
… - MA Motor output
With this, the mains connection and the motor output can be implemented with separate plug connectors in
the case of wall-mounted frequency inverters.
For motor-mounted inverters it is possible to install a mains output plug connector instead of the motor con-
nection. Via this, the mains voltage can be looped to the next device.
ATTENTION
The permissible current load for the connection terminals, plugs and supply cables must be
observed when looping the mains voltage.
