4.7 Installing option modules
9. Place the insulating cover on the mechanical limit switch module by bending the walls of
the rack carefully.
10.Place the basic electronics onto the four holders.
11.Fix the basic electronics using both the fixing screws.
12.Reestablish all electrical connections between the basic electronics and the option
modules. Connect the basic electronics and the option modules to the ribbon cables
provided. Connect the basic electronics and the potentiometer to the potentiometer cable.
13.Using both the screws, fasten the module cover provided. Do not use the standard
14.Select the labels that are already present on the standard version of the module cover
15.Establish all electrical connections.

Protective conductor connector
A protective conductor connector is not required for safety reasons and therefore is not
provided.
Procedure: Setting the limits L1 and L2
1. Move the actuator to the first desired mechanical position.
2. Adjust the upper actuating disk
