bASIc SAfeTy INSTrUcTIONS
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 according to the
specified minimum/maximum values for the application.
•
The wiring must be made with flexible copper cable for a temperature > 75°C.
• Connection of the drive converter is only permissible on symmetrical networks with
a maximum line voltage (L1, L2, L3) with respect to earth (N/PE) of max. 300 V. An
isolating transformer must be used for supply networks which exceed this value ! In
case of non-compliance the control is not longer considered to be a PELV circuit.
• With existing or newly wired circuits the person installing the units or machines must
ensure that the PELV requirements are met.
• For drive converters that are not isolated from the supply circuit (in accordance with
) 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.
1.4.1 eMc-compatible installation
Observance of the limit values required by EMC law is the responsibility of the customer.
Notes on EMC-compatible installation can be found here.

1.4.2 Voltage test
Testing with AC voltage (in accordance with
chapter 18.4) may not be exe-
cuted, since there is danger for the power semiconductors in the drive inverter.
Due to the radio interference suppression capacitors, the test generator will
switch off immediately with a current fault.
According to
it is permissible to disconnect already tested com-
ponents. Drive converters of the KEB Automation KG are delivered ex works
voltage tested to 100% according to product standard.
1.4.3 Insulation measurement
An insulation measurement (in accordance with
chapter 18.3) with DC
500 V is permissible, if all power unit connections (grid-connected potential) and all con-
trol connections are bridged with PE. The insulation resistance of the respective device
can be found in the technical data.
