Compact Operating Instructions – MOVIMOT

Operation
Systems with integrated MOVIMOT
®
inverters must be equipped with additional moni-
toring and protection devices, if necessary, according to the applicable safety guide-
lines, such as the law governing technical equipment, accident prevention regulations,
etc. Additional preventive measures may be required for applications with increased
hazard potential.
Do not touch live components and power connections immediately after separation of
the MOVIMOT
®
inverter from the supply voltage because there may still be some
charged capacitors. Wait for at least 1 minute after having switched off the supply volt-
age.
As soon as supply voltages are present at the MOVIMOT
®
inverter, the connection
box must be closed, i.e. the MOVIMOT
®
inverter and, if applicable, the connector of
the hybrid cable must be installed and connected with all four screws. The MOVIMOT
®
drive only achieves the guaranteed IP degree of protection and resistance against vi-
brations and impacts when the MOVIMOT
®
inverter is securely screwed onto the con-
nection box with 4 screws. Operation with inverter installed but not fully screwed on
may significantly reduce the service life of the drive.
The fact that the operation LED and other display elements are no longer illuminated
does not indicate that the unit has been disconnected from the supply system.
Mechanical blocking or internal safety functions within the unit can cause the motor to
stop. Eliminating the cause of the problem or performing a reset may help to restart
the drive automatically. If this is not permitted for the driven machine for safety rea-
sons, disconnect the unit from the grid before correcting the error.
NOTICE!
Danger of burns: The surface temperature of the MOVIMOT
®
drive and the
external options, e.g. the braking resistor heat sink, can exceed 60°C during opera-
tion.
