Important information about voltageareas 10
WARNING
Dangerous contact voltage in the event of ground faults
(e.g., because the FI circuit breaker has not tripped or the star point connection is "free")
VersaPoint terminals for the 120 V AC and 230 V AC voltage areas should only be operated
in grounded AC voltage networks (AC networks).
Structure of a 120 V AC/230 V AC area
A 120 V AC/230 V AC area must have a power terminal at one end and an end terminal at
the other.
I/O terminals for these voltage areas can be used between these terminals. The number of
terminals is limited by the system limits of the bus system and the VersaPoint system (see
Section 11:, "VersaPoint Modular IO: Technical data").

Fuse protection for a 120 V AC/230 V AC area
Each 120 V AC/230 V AC area must be protected by its own external fuse. Select the rating
of the fuse according to the strength of the cable. The maximum fuse value is 8 A. For
additional restrictions, please refer to the data sheets for the power terminals.
Connecting the power supply and I/O in the 120 V AC/230 V
AC area
WARNING
The supply voltage must only be provided at the appropriate power terminal.
If you provided voltage to several places in an incomplete VersaPoint station, there would
be a danger of touching live parts.
The connecting cables of all actuators and sensors must only be connected to the
VersaPoint terminals for the relevant voltage area. The use of external bus bars for group
potentials is not permitted.
Interrupting PE jumpering in the 120 V AC/230 V AC area
The PE jumper begins at the power terminal of the 120 V AC/230 V AC area and, in a
complete AC voltage area, ends at the end terminal.
If a terminal is removed from this area, the PE jumper is interrupted.
If the installation instructions have been followed, all subsequent terminals will be
disconnected.
3.3.4 Electronics base and connectors for the different voltage
areas
Motor starter terminals are located in a power housing.
Low-level signal terminals and low voltage terminals are located in the same type of
housing, which is referred to as low-level signal housing. An external feature that
distinguishes the base and the corresponding connectors of low voltage terminals from
the base and connectors of low-level signal terminals is their color:

3.3.5 Safety mechanisms to prevent incorrect connection of
terminals for different voltage areas
Protection against the insertion of 24 V DC terminals and
motor starter terminals in the 120 V AC/230 V AC area
Low-level signal terminals and motor starter terminals cannot be snaped-on within a low
voltage area because there is no keyway on the right-hand side of the low voltage
terminals (120 V AC/230 V AC).
WARNING
Dangerous contact voltage
The power terminals for the 24 V DC area can be inserted in a 120 V AC/230 V AC area. The
minimum isolating distance in this case is the distance between two adjacent connectors.
This isolating distance is not permitted. Therefore, only use end terminals that are
designed for terminating the 120 V AC/230 V AC area.
Protection against the connection of 24 V connectors to 120
V AC/230 V AC terminals
The two terminal points for the low voltage I/O terminals are closed using filler plugs. The
connectors for low-level signal terminals therefore do not fit on the low voltage terminals.
Exception 1: The low-level signal connectors can be plugged into 120 V AC/230 V AC
power terminals.
This connection error has no hazardous effect on the electrical components, but it can lead
to system malfunctions.
Only the appropriate connectors should therefore be plugged into the low voltage power
terminals.
Exception 2: The low-level signal connectors can be plugged into relay terminals. Because
the relay outputs are floating, this connection error has no adverse effects.
Protection against the connection of live 120 V AC/230 V AC
connectors in the 24 V DC area
If the connectors for the I/O terminals are wired according to the installation instructions,
they are disconnected from the power supply when removed.
The following connectors may be live in the low voltage area:
1. Connectors of the power terminals for the 120 V AC and 230 V AC areas
2. Connectors for relay terminals
These connectors are closed using filler plugs in some places and therefore do not fit on
the terminals of the 24 V area.

3.3.6 Response to the connection of a 120 V AC or 230 V AC
terminal in the 24 V DC area
An AC terminal can be inserted in the 24 V DC area. The effects are described in Table 3.
Important
A 24 V DC terminal cannot be inserted accidentally in an AC area as these terminals are not
mechanically compatible.
Table 3 Response to the connection of an AC terminal in the 24 V DC area
AC terminal in the 24 V DC
area
Effect/description
AC power terminal in the 24 V
DC area
Specified interface between a 24 V DC area and an AC area. The
AC power terminal consists of two function parts:
—The left-hand part interrupts the jumpering of US, UM, GND,
and FE
—The connections for the power supply and the jumper
contacts for L, N, and PE are on the right-hand part
Digital AC output terminal in
the 24 V DC area
No direct danger to people.
If the output is activated, the Triac output may be forced to trip
and no longer switch off because the supply voltage does not
pass through zero.
NOTE: Possible malfunction
This is likely to be caused by a malfunction of the
actuator connected to the relevant output.
Digital AC input terminal in
the 24 V DC area
No danger to people or machines.
The input does not function due to missing ground.
AC end terminal in the 24 V
DC area
No danger to people or machines.
The terminal offers neither diagonal routing nor connector
connection.
