Waste disposal
Recycle metal and plastic materials. Ensure professional disposal of assembled PCBs.
The product-specific safety and application notes given in these instructions must be
observed!

Residual hazards
Protection of persons
The motor surfaces can become very hot. Danger of burns when touching!
z
Install a guard, if necessary.
High-frequency voltages can be capacitively transferred to the motor housing
through the inverter supply.
z
Carefully earth the motor housing.
Danger of unintentional starting or electrical shocks
z
Perform connection work only in the de-energised state, only with motor in
standstill.
z
Built-in brakes are not fail-safe brakes.
Device protection
Built-in thermal detectors are not a full protection for the machine.
z
If necessary, limit the maximum current, perform a function block
interconnection with disconnection after a few seconds of operation with I
> I
N
, particularly if a danger of blocking exists.
z
The integrated overload protection does not prevent overload under all
conditions!
Built-in brakes are not fail-safe brakes .
z
Speed reduction is possible.
Fuses are not a motor protection.
z
Use current-dependent motor protection switches for average operating
frequency
z
Use built-in thermal detectors at high operating frequency.
Excessive torques lead to a break of the motor shaft or demagnetisation
z
Do not exceed the maximum torques according to the catalogue.
Lateral forces from the motor shaft are possible.
z
Perfectly align shafts of motor and driving machine to each other.
z
Speeds >3000 min
-1
destroy the motor.
Fire protection
Fire hazard
z
Prevent contact with combustible substances.
