BASIC SAFETY INSTRUCTIONS
1.2 Electrical connection
DANGER
Voltage at the terminals and in the device !
Danger to life due to electric shock !
► For any work on the unit switch off the supply voltage and secure it
against switching on.
► Wait until the drive has stopped in order, that perhaps regenerative
energy can be generated.
► Wait untill the DC-Link capacitors are discharged (5 minutes). Verify
by measuring the DC voltage at the terminals.
► Never bridge upstream protective devices (also not for test purpos-
es).
For a trouble-free and safe operation, please pay attention to the following instructions:
• The electrical installation shall be carried out in accordance with the relevant re-
quirements.
• Cable cross-sections and fuses must be dimensioned by the user accordly to the
speciedminimum/maximumvaluesfortheoperation.
• Within systems or machines the person installing electrical wiring must ensure that
on existing or new wired safe ELV circuits the EN requirement for safe insulation is
still met!
• For drive converters that are not isolated from the supply circuit (in accordance with
EN 61800-5-1) all control lines must be included in other protective measures (e.g.
double insulation or shielded, earthed and insulated).
• When using components without isolated inputs/outputs, it is necessary that equi-
potential bonding exists between the components to be connected (e.g. by the equi-
potential line). Disregard can cause destruction of the components by equalizing
currents.
1.3 Start-up and operation
The drive converter must not be started until it is determined that the installation com-
plieswiththemachinedirective;AccountistobetakenofEN 60204-1.
WARNING
Software protection and programming !
Hazards caused by unintentional behavior of the drive!
► Check especially during initial start-up or replacement of the drive
converter if parameterization is compatible to application.
► Securing a unit solely with software-supported functions is not suf-
cient.Itisimperativetoinstallexternalprotectivemeasures(e.g.
limit switch) that are independent of the drive converter.
► Secure motors against automatic restart.
