Methods of line connection
A distinction is made between the following line connection types:
● Line connection components to be directly connected to the line supply
● Operation of the line connection components via an autotransformer
● Operation of the line connection components via an isolating transformer
Figure 3-29 Overview of line connection variants
Danger to life due to electric shock if isolating transformer is omitted
To implement safe electrical separation, an isolating transformer must be used with high
voltages.
• Install an isolating transformer for voltages of > 3-phase 480 VAC +10% or 240 VAC
+10%.
