4.2.4.2
A power terminal is used to supply the required voltages to the internal station potential
jumpers. Several power terminals can be used in one station. This means that different
circuits can be electrically isolated and areas with different voltages can be created within
the station (e.g., 24 V DC and 230 V AC).
All power terminals are used to supply the main voltage and/or segment voltage.
A 24 V supply voltage is also supplied at the IB IL 24 PWR IN/R-PAC and
IB IL 24 PWR IN/PS-PAC terminals, from which the communications power U

Depending on the power terminal, it is possible to work with 24 V DC, 120 V AC or 230 V AC
within an Inline station.
To utilize different voltage areas within a station, a new power terminal must be used for
each area.
WARNING: Dangerous contact voltage
When the power terminal is removed, the metal contacts are freely accessible. With 120 V
AC or 230 V AC power terminals, it should be assumed that dangerous contact voltage is
present. You must disconnect power to the station before removing a terminal.
If these instructions are not followed, there is a danger of damage to health or
even of a life-threatening injury.
Observe safety notes
Observe the notes provided in "Important information about voltage areas" on page 3-1
when using voltages outside the SELV area.
