5.3 Electrical connection
As supplied, the product is configured so that the M8 connector
carries both the power as well as the logic parts for the integrated
gripper control system. If your application requires the power and
logic parts to be separated, for instance if you would like to use an
external relay to ensure that the gripping force is safely switched
off (cf. "safe torque off", STO), then the power and logic parts can
be supplied separately (see Fig. "Equivalent circuit for the power
supply"). The power and logic supply are not electrically isolated so
they must use the same power supply unit (see Fig. "Connection
type common supply to load and logic"). If the supply to the load is
to be switchable in operation, then the connection can be
arranged as shown in "Connection type supply to load separate
from supply to logic".
