Preparing the electrical installation
6.3.1
Supply voltage
For commissioning and operating the LMS1xx, type-dependent the following power supply
voltages as per IEC 60 364
4
41 as well as power drains of the custome-specific power
supply unit are required:
For recommended fuse values, please see
Section “Protection of Supply Cables” on
.
Use safety transformer
The output circuit of the power supply must be safely electrically isolated from the input
circuit, this feature is normally provided by a safety transformer in accordance with IEC 742
(VDE 0551).
6.3.2
Wire cross-sections
Wire all connections with copper cables!
Use the following wire cross-sections:
