2.3 Electrical connection
DANGER
For a trouble-free and safe operation, please pay attention to the following instruc-
tions:
•
The electrical installation shall be carried out in accordance with the relevant
requirements.
•
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 controllers that are not isolated from the supply circuit (in accordance
with
measures (e.g. double insulation or shielded, earthed and insulated).
•
When using components without isolated inputs/outputs, it is necessary that
equipotential bonding exists between the components to be connected (e.g. by
the equipotential line). Disregard can cause destruction of the components by
equalizing currents.
2.4

Start-up and operation

The drive controller must not be started until it is determined that the installation
complies with the machine directive; Account is to be taken of
WARNING
16
Electrical voltage at terminals and in the device!
Danger to life due to electric shock!
➢ For any work on the device 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 purposes)
EN 61800-5-1) all control lines must be included in other protective
Software protection and programming!
Danger due to unintentional behaviour of the drive!
➢ Check especially during initial start-up or replacement of the drive
controller if the parameterization is compatible to the application.
➢ Securing a unit solely with software-supported functions is not suffi-
cient. It is imperative to install external protective measures (e.g. limit
switch) that are independent of the drive controller.
➢ Secure motors against automatic restart.
