15.3.1 Connecting the power supply
The cross-sectional area of the +24 V cables used to supply power must be
sized for the maximum output current drawn by each group.
It is impermissible to apply a voltage, at any output, that exceeds the supply
voltage by more than 0.7 V.
15.3.2 Connecting EN 61131-2 short-circuit proof digital outputs
The outputs are able to drive twice their rated operational current briefly
when driving loads with higher inrush currents.
The outputs can be switched off by groups by using the corresponding group
power supplies.

15.3.4 Suppressor circuit for inductive loads
Induced voltages may be produced when inductive loads are switched off.
Accordingly, the transistor outputs have internal suppressor circuits to +24 V
in order to protect the XN300 slice module.
