9 Mains and environment
Mains voltage, power system, and ambient conditions are decisive for the operation of the drive sys-
tem.
9.1 Electrical supply system
Select the supply system the drive system is to be connected to. For an inverter with DC supply, se-
lect the supply system of the energy supplier.
9.1.1 Power system
In the following the power systems which can be selected in the DSD and which are in use world-
wide are described in detail.
Earthed power systems
TT and TN systems are power systems with an earthed neutral. They are used in most countries. In
some countries, power systems with earthed phase conductors are also used.
Supply system Supply frequency Power system Note
1AC 230 V 50 Hz TN/TT system
IT system
• Europe, Asia, Africa and Australia
have a mains frequency of 50 Hz.
• The mains frequency of 60 Hz (North
America) is not supported by the DSD.
• Select a rated mains voltage of 400 V
for 380-V systems.
