the type plate.
Only all-current-sensitive RCD protective devices
(type A) are permissible. Like frequency inverters, RCD protective
devices cannot provide personal safety while operating the device.
With open loop speed control using transformers or electronic volt-
age regulators (e.g. phase angle control), excessive current may
occur.
In addition, noises can occur with phase control, depending on the
manner in which the device is installed.
Fit sinusoidal filters that work on all poles (live-live and live-earth)
between the frequency inverter and the motor for operation with
frequency inverters.
WARNING
Device without overheating protection
The device is delivered without any automatically functioning overhe-
ating protection. The device can become hot and burn.
➜ For the version without TOP, install an additional, suitable motor
(Applicable only to devices without off-board TOPs)
CAUTION
Electrical voltage
The device is a built-in component and features no electrically isolat-
ing switch.
➜ Connect the device only to circuits that can be switched off using

The motors are equipped with thermal overload protectors to protect
the devices.
Check to make sure that the thermal overload protector is correctly
connected before each operation.
Failure to connect up the thermal overload protector correctly will
invalidate your right to claim damage for any defects. (Applicable
only to devices with off-board TOPs)
