Operation
Systems in which MOVIFIT
®
is installed must, if necessary, be equipped with addition-
al monitoring and protection devices according to applicable safety regulations; e.g.,
the German law governing technical equipment (Gesetz über technische Arbeitsmit-
tel), accident prevention regulations, etc. Additional protective measures may be nec-
essary for applications with increased hazard potential. Changes to MOVIFIT
®
using
the operating software are permitted.
Do not touch live components or power connections immediately after disconnecting
the MOVIFIT
®
from the supply voltage because there may still be some charged ca-
pacitors. Wait at least for 1 minute after having switched off the supply voltage.
As soon as supply voltage is present at the MOVIFIT
®
, the ABOX must be closed i.e.,
the MOVIFIT
®
EBOX and any hybrid cable connector must be connected and screwed
on.
Do not disconnect the EBOX of the MOVIFIT
®
or any power plug connectors during
operation. Doing so can lead to dangerous electric arcs forming, which can cause ir-
reparable damage to the unit (fire risk, irreparable contacts).
Important: The MOVIFIT
®
maintenance switch disconnects only the integrated fre-
quency inverter from the grid. The terminals of the MOVIFIT
®
unit are still connected to
the line voltage 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.
Mechanical blocking or internal safety functions of the unit can cause a motor stand-
still. Eliminating the cause of the problem or performing a reset may result in the drive
re-starting automatically. If this is not permitted for the driven machine for safety rea-
sons, disconnect the unit from the supply system before you start correcting the error.
Caution: Risk of burns: The surface temperature of the MOVIFIT
®
and the external op-
tions, e.g. the braking resistor heat sink, can exceed 60 °C during operation.
