ABB REL650 - Interlocking for Line Bay ABC_LINE (3)

If, in this case, line voltage supervision is added, then rather than setting 989 to open state,
specify the state of the voltage supervision:
• 989_OP = VOLT_OFF
• 989_CL = VOLT_ON
If there is no voltage supervision, then set the corresponding inputs as follows:
• VOLT_OFF = 1
• VOLT_ON = 0
