for a mobile system like described, discrete inputs are required.
CAUTION
Please note that the maximum voltages, which may be applied at the discrete inputs are defined as fol-
lows. Voltages higher than those specified destroy the hardware!
Maximum input range: +/-4 to 40 Vdc.

To monitor a phase rotation relay, the alarm input [D03] must be used.
If it is required to block an automatic mains failure start, the discrete input [D11] must be programmed to "Inhibit
emergency run".

Discrete input [D03] "Phase rotation check O.K.":
This control input is evaluated if the busbar is energized. In case of a
failure, the message "Phase sequence" is displayed and closing the cir-
cuit breakers is blocked. If the busbar phase rotation shall not be
monitored, this input must be energized permanently.
