Switching at the output
Switching between motor and drive inverter is prohibited for single drives during oper-
ation as this may trigger the protection gear of the device. Function speed search must
be activated if switching can not be avoided. Control release may only be triggered after
closing the motor contactor (e.g. by switching the control release).
Connecting and disconnecting is permissible with multiple motor drives if at least 1 mo-
tor is running during the switch-over process. The drive inverter must be dimensioned to
the occurring starting currents.
Short-circuit resistance
The drive inverters are conditional short-circuit proof. After resetting the internal protec-
tion devices, the function as directed is guaranteed.

Installation, configuration or program errors can cause malfunc-
tions or total failure of other CAN bus nodes!
► The programming of the customer software must be carried out in
such a way that other CAN bus nodes continue to function in error
case.
► The programming of the customer software must be tested by the
customer in the application.
► Observe cable length and transmission speed.
► Terminate the bus line with terminating resistors.
► The customer assumes the responsibility for the installation, custom-
er software or parameterization.
High temperatures at heat sink and coolant!
burning of the skin!
► Cover hot surfaces safe-to-touch.
► If necessary, attach warning signs on the system.
► Before touching, check the surface and cooling water lines.
► Before working let the unit cool down.
The supplied plastic cap is only a transport protection.
Degree of protection can only be maintained when connected.
Use only approved accessories for this device.
Never touch terminals or cable ends.
If an earth-leakage fault or short-circuit often occurs at the output, this can lead to a
defect in the unit.
If a short-circuit occurs during regenerative operation (2nd or 4th quadrant, regener-
ation into the DC link), this can lead to a defect in the unit.
