Electrical connection
Each actuator requires a Contrac electronic unit. Proper actuator operation requires an actuator specific
software loaded in the associated electronic unit. Compare 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 plug at the actuator and with screw terminals at the electronic
unit.
