3.2 Customer units
(Customer Units, Option)
Customer units are optional push-in modules whose slots are
located inside the frequency inverter. Following insertion and
switching on the mains supply, they are automatically identified
by the inverter, and the required parameters are made available.
Cable connection is via direct plug-in clip connectors with spring
terminals. This makes the connection of devices very easy and
convenient.

NOTE
, for 5V / 15V power supplies
The customer units and special extension units currently have various power supplies (5V / 15V) that can
be used externally. The maximum permissible external load current is 300mA. This can be taken from
one or more power supplies. The total current must however not exceed 300mA.
All control voltages are based on a common reference potential!
Potentials AGND /0V und GND /0V are internally linked in the device.
