Access to boards

Before you can wire the push button extensions, you must gain access to the boards. The procedures differ
slightly according to the device.
For the CP2xxx and CP39xx Control Panels with connection block, you only have to remove the cover for
access. To do this, first loosen the M3 screws and then remove the cover (see Fig. 19).

3. Loosen and remove the M3 screws from the cable channel (section C).
