10. Electrical Connection
Each actuator requires a Contrac electronic unit. Proper actuator operation requires an actuator spe-
cific software loaded in the associated electronic unit. See electronic unit instructions for details. Com-
pare the data labels on both, electronic unit and actuator, in order to ensure a correct hardware and
software assignment.
The electrical connection is done with a combined plug on the actuator and with screw terminals on the
electronics.
See instructions 42/68-821 for wiring diagram for electronic units for mounting rack installation.

The following steps must be performed to switch the actuator to automatic mode (AUT):
-
Activate digital inputs DI 1, DI 2 and DI 3 via the configuration program.
-
Make sure that the supply voltage is available on digital input 1 (DI 1).
-
Activate AUT mode via the configuration program.
