Note
The actual intervals at which maintenance procedures are to be performed depend on the
environmental and operating conditions. Define maintenance intervals that reflect your plant-
specific environmental and operating conditions and meet your availability requirements. When
doing so, take the prescribed maintenance intervals into consideration, as well as the
instructions for repairing and replacing installed components.

Opening the device
The door of the closed-loop control cabinet is not electromechanically interlocked. For this
reason, it can also be opened during operation.
Using a switch at the control cabinet, you can release the electromagnetic door interlocking for
air-cooled power units. The electromechanical door interlock system is designed to protect
personnel and is an integral part of the safety concept. During operation and when the circuit
breaker is closed, all the doors are interlocked (with the exception of the door for the control
section).
The conditions to enable the door release can be found using parameter r6586 (VECTOR). The
parameter indicates the actual status. For further information, please refer to the List Manual.
