Switch S1

Switch S1 on the MASTERDRIVES braking unit is used to set the switch-on threshold. It is
located behind the front panel.
Switch S1 should be set to "high" (factory setting) in order to operate the braking unit on a
SINAMICS S120 drive line-up in booksize format. This means that the switch-on threshold is
at 757 V DC.
For more information, refer to the operating instructions for the MASTERDRIVES braking
unit.
