Step 1

-   De-energize the device.

-   Remove the screw cap.

-   Using a suitable screwdriver (with as wide a blade as possible), remove 

  the screws at left and right of the profibus module.

Step 2

To help pull out the module, connect the device lead (or other suitable line) 

directly to the terminals (Fig. 1).

Step 3

Carefully lift the basic module up and out of the housing. Be sure that at the 

lower section of the module the ribbon cable for connecting the sensor to a plug 

connector remains attached.

Turn the basic module to the side. While doing this, avoid putting any tension on 

the connecting lead to the sensor (Fig. 2-3).

Step 4

Disconnect the sensor connecting lead from the basic module (plug connector) 

(Fig. 4).

Caution: Avoid touching the plug connector at the bottom of the basic module 

with your fi

ngers since dirt (grease, moisture) and electrostatic discharge could 

damage the device. The sealing washer below the basic module can remain in 

the device housing.
