Figure 3-1 Connection diagram: PM240 Power Module with Brake Relay
Star connection and delta connection
With SIEMENS motors, you will see a
diagram of both connection types on
the inside of the terminal board cover:
• Star connection (Y)
• Delta connection (Δ)
The motor rating plate provides
information about the correct
connection data:
e.g.: 230/400V Δ/Y means that for a
400V line supply, the motor is
connected up in the Y connection.
