Current legislation states that that in order to prevent tampering and potentially hazardous
programming errors, access to the pass codes required to enter commissioning mode should

The pass code for commissioning mode is contained in the detachable section at the front of
this manual. This section must be removed after commissioning and kept in a safe,
access controlled location.
