3.3 Customer unit overview
Customer units are optional push-in modules. Their slots are located on the left guide rail inside the frequency
inverter housing. After insertion, they are automatically identified by the frequency inverter.
The cable connection is established using spring terminals. This makes the connection of devices very easy
and convenient.
NOTE
With the customer units (SK CU1- …) there is no difference between IP protection classes. This
means that the same customer units are used for both the air cooled SK 750E (IP54) and for the
water cooled version (IP65).
