Procedure:
1.
Danger to life due to electric shock
• Ensure that the three-pole circuit breaker is switched off and cannot be reconnected.
2. Release all screws of the lower enclosure lid using an Allen key (AF 3).
3. Lift and remove the lower enclosure lid from
below.
4. Remove the adhesive tape from the enclosure opening for the AC connection.
