COMBIVERT G6 contain dangerous voltages which can cause
death or serious injury.
The COMBIVERT G6 can be adjusted by way that in regenera-
tive operation energy is regenerated into the DC link also during
mains power failure. Therefore a dangerous high tension can
exist in the unit after switching off the supply system.
Before working with the unit check the isolation from sup-
ply by measurements in the unit.
Care should be taken to ensure correct and safe operation to
minimise risk to personnel and equipment.

Uncontrolled start is possible by improper installation of the safe-
ty technology. This may cause death, serious bodily injuries or
substantial damage to property.
Therefore the safety function may only be installed and put into
operationbyqualiedpersonnelwhicharetrainedinsafetytech-
nology.
Observe
Standards
The COMBIVERT G6 must not be started until it is determined
that the installation complies with 2006/42/EC (machine direc-
tive) as well as the EMC directive (2004/108/EC)(note EN60204).
The COMBIVERT G6 meets the requirements of the Low-Volt-
age Directive 2006/95/EC. The harmonized standard of the se-
ries EN 61800-5-1 (VDE 0160) is used.
This is a product of limited availability in accordance with IEC
61800-3. This product may cause radio interference in residen-
tial areas. In this case the operator may need to take correspond-
ing measures.
With electronic protection devices the safety function is integrated in the drive control in order
to minimize or eliminate danger by malfunctions in machines. The integrated safety function
replace the complex installation of external safety components. The safety function can be
requested or released by an error.
Regular
checks
In order to ensure permanent security, the function must be
checked in regular intervals according to the results of the risk
analysis.
Installation work or troubleshooting can be necessary in hazard areas, whereby protective
devices such as line- or motor contactors shall not be activated. The safety function STO can
be used there. Depending on the application the use of line or motor contactors can be void
by using STO.
In case of error or request, the power semiconductor of the drive module are switched off and
the drive is not supplied, which causes a rotation or torque (in case of a linear drive move-
ment or force). The unit can be safe switched off and/or remain if an error occurs.
