bASIC SAFETY INSTRUCTIONS
Restrictions for systems with earthed phase conductor (delta power system)!
►
The control system is no longer regarded as “securely isolated circuit”, further pro-
tection measures are therefore required.
►
With this type of power system, the max. voltage phase / earth must not exceed
528 V absolute.
If personnel protection is required during installation of the
system, suitable protective devices must be used for drive
converters.

Installations which include drive converters shall be equipped with additional control and
protective devices in accordance with the relevant applicable safety requirements, e.g.
act respecting technical equipment, accident prevention rules etc.. They must always be
complied with, also for drive converters bearing a CE marking.
1.5.1
EMC-confirm installation
Observance of the limit values required by EMC law is the responsibility of the manufac-
turer of the installation or machine.
Notes on EMC-compatible installation can be found here.

1.5.2 Voltage test
Testing with AC voltage (in accordance with EN 60204-1 Chapter 18.4) may not be exe-
cuted, since there is danger for the power semiconductors in the drive converter.
Because of the noise suppression capacitors the test generator will immedi-
ately trigger with current error.
Accordng to EN 60204-1 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.
1.5.3 Insulation measurement
An insulation measurement (in accordance with EN 60204-1 chapter 18.3) with 500 Vdc
is permissible, if all power unit connections (grid-connected potential) and all control
connections are bridged with PE. At any unit it can be expected with an insulating re-
sistance > 5 MΩ !
