Safe disconnection
MOVIFIT
®
SC meets all requirements for safe disconnection of power and electronic
connections in accordance with EN 61800-5-1. All connected circuits must also satisfy
the requirements for safe disconnection.
2.9
Operation
Systems into which MOVIFIT
®
SC is installed must be equipped with additional moni-
toring and protection devices, if necessary, according to the applicable safety regula-
tions; e.g. the law governing technical equipment, accident prevention regulations, etc.
When used in applications with an increased potential for risk, additional preventive
measures may be necessary. Changes to the MOVIFIT
®
SC using the software are
permitted.
Do not touch live components or power connections immediately after disconnecting the
MOVIFIT
®
SC from the supply voltage because there may still be some charged capac-
itors. Wait at least 1 minute after the supply voltage is switched off.
As soon as supply voltage is present at the MOVIFIT
®
SC, the terminal box must be
closed (i.e., the MOVIFIT
®
-EBOX and any hybrid cable connector must be connected
and screwed on).
The EBOX of the MOVIFIT
®
SC and any power plug connectors may never be discon-
nected during operation. Doing so can lead to dangerous electric arcs forming, which
can cause irreparable damage to the unit (fire risk, irreparable contacts).
Important: The MOVIFIT
®
maintenance switch only disconnects the integrated motor
circuit breaker from the power supply system. The terminals of the MOVIFIT
®
SC are
still connected to the mains 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 internal safety functions of the unit can cause a motor standstill.
Removing 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.
Danger of burns: The surface temperature of the Compact MOVIFIT
®
SC can exceed
more than 60 °C [140 °F] during operation.
Do not connect terminals X9 and X91 in "single-motor" operating mode.
