Firmware and hardware versions
This documentation refers to the firmware and hardware version that was applicable at the time the
documentation was written.
The module features are continuously improved and developed further. Modules having earlier production
statuses cannot have the same properties as modules with the latest status. However, existing properties
are retained and are not changed, so that older modules can always be replaced with new ones.
The firmware and hardware version (delivery state) can be found in the batch number (D-number) printed on
the side of the EtherCAT Box.
Syntax of the batch number (D-number)
D: WW YY FF HH
WW - week of production (calendar week)
YY - year of production
FF - firmware version
HH - hardware version
Example with D no. 29 10 02 01:
29 - week of production 29
10 - year of production 2010
02 - firmware version 02
01 - hardware version 01

2 Product group: EtherCATPBox modules
EtherCATP
EtherCATP supplements the EtherCAT technology with a process in which communication and supply
voltages are transmitted on a common line. All EtherCAT properties are retained with this process.
Two supply voltages are transmitted per EtherCATP line. The supply voltages are electrically isolated from
each other and can therefore be switched individually. The nominal supply voltage for both is 24VDC.
EtherCATP uses the same cable structure as EtherCAT: a 4-core Ethernet cable with M8 connectors. The
connectors are mechanically coded so that EtherCAT connectors and EtherCATP connectors cannot be
interchanged.
EtherCATP Box modules
EtherCATP Box modules are EtherCATP slaves with degree of protection IP67. They are designed for
operation in wet, dirty or dusty industrial environments.
EtherCAT basics
A detailed description of the EtherCAT system can be found in the EtherCAT system documentation.

EtherCATPBox with diagnostics, TwinSAFESC
The space-saving EPP9022-9060 EtherCATPBox is suitable for the diagnosis and measurement of the
voltages US and UP as well as the currents IS and IP or for measuring these variables both temporarily during
commissioning and permanently during system operation. The voltage range is displayed on the box by the
LEDs (green, yellow and red) even without an EtherCAT master. In a running EtherCAT network the values
of US, UP, IS and IP can also be read out as process data in the master. The voltage levels for the LED
displays can be adjusted by CoE. In addition there is an M8 power socket on the EPP9022-9060 to which an
external multimeter can be connected for measuring the voltages.
With the help of the TwinSAFESC technology it is possible to make the measured values from the
EPP9022-9060 usable for safety tasks. A corresponding application example can be found in the TwinSAFE
Application Guide. The user bears the responsibility for the safety evaluation in case of deviation from the
application example.

3.3 Scope of supply
Make sure that the following components are included in the scope of delivery:
• 1 EPP9022-9060 EtherCAT P Box
• 1x protective cap for EtherCATP socket, M8, red (pre-assembled)
• 1x protective cap for supply voltage output, M8, black (pre-assembled)

NOTE
Dirt during assembly
Dirty connectors can lead to malfunctions. Protection class IP67 can only be guaranteed if all cables and
connectors are connected.
• Protect the plug connectors against dirt during the assembly.
Mount the module with two M3 screws on the mounting holes in the corners of the module. The mounting
holes have no thread.
4.1.3 Functional earth (FE)
The upper mounting holes also serves as a connection for functional earth (FE).
Make sure that the box is grounded to low impedance via the functional earth (FE) connection. You can
achieve this, for example, by mounting the box on a grounded machine bed.

Protective caps
• Seal unused connectors with protective caps.
• Ensure the correct seating of pre-assembled protective caps.
Protective caps are pre-assembled at the factory to protect connectors during transport. They may not
be tight enough to ensure IP67 protection.
