1.2 Operating Booksize Line Modules directly on the line
supply
The SINAMICS S Booksize converter system is rated for direct operation on TN,
TT and IT line systems with rated voltages of 3 AC 380 V to 3 AC 480 V ±10% (-
15% < 1 min) 50 Hz to 60 Hz and overvoltage Category III according to EN 61800-
5-1.
Grounded TN and TT line systems can be implemented with grounded neutral
point or grounded line conductor. For line supplies with grounded line conductor,
carefully observe the notes on increased motor insulation stress, provided in the
corresponding equipment manuals and this manual.
Direct connection to the line supply is shown in the following diagram using an
Active Line Modules Booksize as example.
