1.3 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 no regenerative energy
can be generated.
►
Await capacitor discharge time (5 minutes) if necessary, measure
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 according to the design of
the machine manufacturer. Specified minimum / maximum values may not be fallen
below /exceeded.
• With existing or newly wired circuits the person installing the units or machines must
ensure the EN requirements are 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.
1.4 Start-up and operation
The drive converter must not be started until it is determined that the installation com-
plies with the machine directive; Account is to be taken of
EN 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-
ficient. It is imperative to install external protective measures (e.g.
limit switch) that are independent of the drive converter.
►
Secure motors against automatic restart.
