The intermediate circuit or the 230 V mains voltage must always be
switched off before the 24 V logic power supply

is switched off.

Warning

Work in the vicinity of the machine must only be carried out
when the AC or DC power supply is switched off and locked.

Switched-off final stage or switched-off controller enable are not
suitable locking conditions. In the event of a fault, this could lead
to unintentional movement of the drive.

Warning

Carry out commissioning with a free-running motor in order to
avoid mechanical damage, e.g. due to incorrect direction of
rotation.

Warning

Electronic devices are never fail-proof.

The user is responsible for ensuring that his system is brought into
a safe state if the electric device fails.

Warning

DANGER!

The motor controller and, in particular, the brake resistance can
take on high temperatures, which can cause severe bodily burns on
contact.

2.4.3

Protection aganst touching electric components

This section concerns only devices and drive components with voltages over 50 V. It is
dangerous to touch components with voltages of more than 50 V, as this can cause an
electric shock. When electric devices are operated, certain components in these devices
are always under dangerous tension.

Warning

Dangerous voltage

High voltage!

Danger of death or serious bodily injury due to electric shock!

For operation, the relevant DIN, VDE, EN und IEC regulations, as well as all national and
local safety and accident prevention regulations must always be observed. The system
manufacturer or the user is responsible for ensuring that these regulations are observed.
