Power connection
Unscrew the four bolts from the housing cover of the drive control and remove the cover.
Guide the power cord through the cable connection and connect the phases to contacts
L1, L2, L3 and the ground cable to the PE contact of the connection terminal. The cable
provides strain relief, and the PE connection line has to be connected in a leading fashion
(considerably longer).
If a brake resistor is connected, screened and doubly insulated lines must be used.
