WARNING! Make sure that the disconnector of the supply transformer is locked to open position,
ie, no voltage is, or can be, connected to the drive inadvertently. Check also by measuring that
there is no voltage connected.
Check that the mechanical and electrical installation of the
brake chopper has been inspected and is OK.
Check that the insulation of the resistor circuit has been
measured and is OK.
