Operation
Systems with integrated DRC drive units must be equipped with additional monitoring
and protection devices according to the applicable safety guidelines, such as the law
governing technical equipment, accident prevention regulations, etc. Additional protec-
tive measures may be necessary for applications with increased potential risk. Changes
to DRC drive units using the operating software are permitted.
Do not touch live components and power connections immediately after separation of
the DRC drive units from the supply voltage because some capacitors might still be
charged. Wait at least for 10 minutes after the supply voltage has been switched off.
The connection boxes must be closed and screwed on before the supply voltages are
connected to DRC drive units.
The unit may still be live and connected to the power supply even if the operation LEDs
and other display elements are no longer illuminated.
Mechanical blocking or internal safety functions of the unit can cause a motor standstill.
Eliminating the cause of the problem or performing a reset may result in the drive re-
starting automatically. If, for safety reasons, this is not permitted for the driven machine,
disconnect the unit from the supply system before correcting the error.
Caution: Danger of burns: The surface temperatures of DRC drive units can be more
than 60 °C during operation.
