Operating Instructions – MOVIFIT
®
-FC
2.9
Operation
Systems into which MOVIFIT
®
-FC is installed may also need to be equipped with addi-
tional monitoring and protection devices, according to the applicable safety regulations;
these include the law governing technical equipment and accident prevention regula-
tions. Additional protective measures may be necessary for applications with increased
potential risk. Changes to MOVIFIT
®
-FC using the operating software are permitted.
Do not touch live components or power connections immediately after disconnecting
MOVIFIT
®
-FC from the supply voltage as there may still be some charged capacitors.
Wait for at least 1 minute after having switched off the supply voltage.
As soon as supply voltage is present at MOVIFIT
®
-FC, the terminal box must be closed
(i.e. the MOVIFIT
®
-EBOX and any hybrid cable connector must be connected and
screwed on).
Never disconnect the EBOX for MOVIFIT
®
-FC or any power plug connectors during
operation. Doing so can lead to dangerous electric arcs forming, which can cause irrep-
arable damage to the unit (fire risk, irreparable contacts).
Important: The MOVIFIT
®
maintenance switch disconnects only the integrated
frequency inverter from the mains. The terminals of MOVIFIT
®
-FC are still connected to
the supply voltage after the maintenance switch is activated.
The unit may still be live and connected to the mains, even if the operation LEDs and
other display elements are no longer illuminated.
Mechanical blocking or the unit's internal safety functions can cause a motor standstill.
Eliminating the cause of the problem or performing a reset can result in the drive
re-starting automatically. If, for safety reasons, this is not permitted for the driven
machine, disconnect the unit from the mains before correcting the fault.
Caution – Danger of burns: The surface temperature of MOVIFIT
®
-FC and the external
options (e.g. the braking resistor heat sink) can exceed 60°C (140°F) during operation.
