5.1.5 Installing passive EtherCAT Terminals
Incorrectly installed passive EtherCAT Terminals
The E-bus signal between an Embedded PC and the EtherCAT Terminals can be impaired due to
incorrectly installed passive EtherCAT Terminals.
Passive EtherCAT Terminals should not be installed directly on the power supply unit.
EtherCAT Terminals that do not take part in active data exchange are referred to as passive terminals.
Passive EtherCAT Terminals have no process image and do not require current from the terminal bus (E-
bus).
Passive EtherCAT Terminals (e.g. EL9195) can be detected in TwinCAT. In the tree structure the EtherCAT
Terminal is displayed without process image, and the value in column “E-bus (mA)” does not change,
compared to the preceding EtherCAT Terminal.
Fig.4: Identifying a passive EtherCAT Terminal in TwinCAT.
The entry "Current consumption via E-Bus" in the technical data of an EtherCAT Terminal indicates whether
a particular EtherCAT Terminal requires power from the terminal bus (E-bus).
The following diagram shows the permissible installation of a passive EtherCAT Terminal. The passive
EtherCAT Terminal was not directly attached to the power supply unit.
Fig.5: Passive EtherCAT Terminals, permissible installation.
The following diagram shows the invalid installation of a passive EtherCAT Terminal.

5.2 Power supply
This chapter describes how to connect the power supply unit CX2100-0004. This documentation uses the
Embedded PC CX2020 to demonstrate the procedure.
5.2.1 Connect Embedded PC
NOTE
Damage to the Embedded PCs
The Embedded PCs may be damaged during wiring.
• The cables for the power supply should only be connected in de-energized state.
The CX2100-0004 power supply units require an external voltage source, which provides 24VDC (-15% /
+20%).
The cabling of the Embedded PC in the control cabinet must be done in accordance with the standard EN
60204-1:2006 PELV = Protective Extra Low Voltage:
• The "PE" and "0V" conductors of the voltage source for a basic CPU module must be on the same
potential (connected in the control cabinet).
• Standard EN 60204-1:2006, section 6.4.1:b stipulates that one side of the circuit, or a point of the
energy source for this circuit must be connected to the protective earth conductor system.
Connection example with CX2020 basic CPU module and CX2100-0004 power supply unit:
Table6: Legend for the connection example.
No. Description
1 The upper spring-loaded terminals identified with "24V" and "0V" supply the basic CPU
module and the terminal bus (data transfer via K- or E-bus).
2 The spring-loaded terminals identified as "+", "-" and "PE" supply the Bus Terminals via
the power contacts and the sensors or actuators connected to the Bus Terminals.

Commissioning
CX2100-000420 Version: 1.2
The cables of an external voltage source are connected to the power supply unit with spring-loaded
terminals.
Table7: Required wire cross-sections and strip lengths.
Conductor cross-section 0,5 ... 2,5 mm2AWG 20 ... AWG 14
Strip length 8 ... 9 mm 0.33 inch
Connect the Embedded PC as follows:
1. Open a spring-loaded terminal by slightly pushing with a screwdriver or a rod into the square opening
above the terminal.
2. The wire can now be inserted into the round terminal opening without any force.
3. The terminal closes automatically when the pressure is released, holding the wire safely and
permanently.
The voltage source has been connected to the power supply unit
successfully when the two upper power supply terminal LEDs light up in
green.
• The left LED (Us) indicates the supply of the basic CPU module and
terminal bus.
• The red LED (Up) indicates the Bus Terminal supply via the power
contacts.
NOTE
Interrupting / switching off the power supply
To switch off the Embedded PC, do not disconnect the ground (0 V), because otherwise current may con-
tinue to flow via the shielding, depending on the device, and damage the Embedded PC or peripheral de-
vices.
• Always disconnect the 24 V line. Devices connected to the Embedded PC, which have their own power
supply (e.g. a Panel) must have the same potential for "PE" and "0 V" as the Embedded PC have (no
potential difference).
