This appliance is conducting dangerous voltages and holds dangerous rotating machines
(ventilators).
Switching cabinets must be equipped with emergency stop devices who are able to cut off all
voltages which can lead to hazards. Not included are appliances that would generate new
hazards after being cut off. The release for the emergency stop device must be placed in a
way that it is fast to reach in case of an emergency. If you carry out operations that hold higher
hazard levels the presence of an additional person is required.

During the first commissioning there is no guarantee that the driven machine elements are
not activated by fault or mistake. Therefore be extra careful during the first commissioning.
Extra care is to be taken when directly or indirectly touching the shaft. This is allowed only
when the shaft is in stand still position and the power module is cut off from voltage. During
operation free accessible machine parts such as shafts or ventilators must be covered.
When an error occurs the drive will be switched off current; the motor will run down without
breaking. This circumstance must be regarded especially in transmission or hauling applica-
tions.
