Gate resistors on the Power board.
9.2.6.3 Voltage related settings on the board
For reliable operation with various types of IGBTs in units, gate resistors have
to be selected according instructions as in section 9.2.6.2.
Voltage programming will be done by the resistors R9 and R19 according to
nominal voltage the board will be installed in. Both resistors are placed on the
board by manufacturer and in prior to determine usage, one of the resistors
has to be cut off.
