Safety Notes
2.10 Operation
Systems with integrated MOVIFIT
®
FDC and MOVIGEAR
®
and DRC drive units must
be equipped with additional monitoring and protection devices according to the applica-
ble safety guidelines, such as the law governing technical equipment, accident preven-
tion regulations, etc. Additional protective measures may be necessary for applications
with increased potential risk. It is permitted to modify MOVIFIT
®
FDC as well as
MOVIGEAR
®
and DRC drive units using the operating software.
Do not touch live components or power connections immediately after disconnecting
MOVIFIT
®
FDC as well as MOVIGEAR
®
and DRC drive units from the supply voltage
because some capacitors may still be charged. Wait at least 5 minutes after having
switched off the supply voltage.
As soon as supply voltage is present at the MOVIFIT
®
FDC or MOVIGEAR
®
and DRC
drive units, the terminal boxes of the units must be closed (i.e. the MOVIFIT
®
EBOX as
well as any connectors of SNI cables or hybrid cables must be plugged in and screwed
on). The degree of protection of MOVIFIT
®
FDC specified in the technical data chapter
applies only if the EBOX is installed on the ABOX.
Never disconnect power plug connectors during operation. Doing so can lead to danger-
ous electric arcs forming, which can cause irreparable damage to the unit (fire risk,
irreparable contacts).
Important: The maintenance switch of MOVIFIT
®
disconnects only the MOVIGEAR
®
and DRC drive units from the power supply system. The terminals of the MOVIFIT
®
FDC
unit are still connected to the power supply after the maintenance switch is activated.
The unit may still be live and connected to the supply system, even if the operation LEDs
and other display elements are no longer illuminated.
The bus cycle and timeout times effective in the system must be taken into account
during project planning and when dimensioning the system.
Mechanical blocking or internal safety functions of the unit can cause a motor standstill.
Removing the cause of this problem or performing a reset can result in the MOVIGEAR
®
and DRC drive unit re-starting on its own. If this is not permitted for the driven machine
for safety reasons, disconnect the unit from the supply system before correcting the er-
ror.
Caution: Danger of burns: The temperature of the surface of MOVIFIT
®
FDC as well as
of MOVIGEAR
®
and DRC drive units can exceed 60
˚
C during operation.
