ETHERLINE® GUARD | Issue 1e | 11.04.2022 6
1.3 Target group of the operating instructions
This description is intended exclusively for trained specialists in control and automation technology who
are familiar with the applicable national standards. For installation, commissioning and operation of the
components, it is absolutely necessary to observe the notes and explanations in these operating
instructions.
Project planning, design and operating errors can impair the proper operation of the ETHERLINE®
GUARD and result in personal injury, property damage or environmental damage.
Only adequately qualified personnel may operate the units!
The qualified personnel must ensure that the application or use of the products described complies with
all safety requirements, including all applicable laws, regulations, provisions and standards.
The minimum length of the Ethernet cable to be monitored is 2m.
Before using the unit, please check whether a newer version of the firmware is available on the website
(for more information on firmware updates, see chapter 9) is available.
1.4 Intended use
The LAPP ETHERLINE® GUARD is used for condition monitoring of Ethernet-based data lines with the
100BASE-TX transmission standard, with a focus on dynamic applications.
All components are delivered with a factory hardware and software configuration. The hardware and
software configuration to suit the application conditions must be carried out by the user. Changes to the
hardware or software configuration that go beyond the documented possibilities are not permitted and will
result in the exclusion of liability on the part of U.I. Lapp GmbH.

ETHERLINE® GUARD | Issue 1e | 11.04.2022 7
The device must not be used as the sole means of averting dangerous conditions on machinery and
equipment.
Faultless and safe operation of the unit requires proper transport, storage, set-up, assembly, installation,
commissioning, operation and maintenance.
The ambient conditions specified in the technical data must be observed.
The unit has protection level IP 20 and must be installed in an electrical operating room or a control
box/switch cabinet to protect it from environmental influences. To prevent unauthorised operation, the
doors of the switch boxes/switch cabinets must be closed and secured if necessary during operation.
1.5 Abuse
The consequences of improper use may include personal injury to the user or third parties, data
protection violations as well as property damage to the control unit, the product or environmental damage.
Only use the unit as intended!
1.6 Assembly / Disassembly
1.6.1 Access restriction
The assemblies are open equipment and may only be installed in electrical operating rooms, cabinets or
enclosures. Access to the electrical operating rooms, cabinets or enclosures must only be possible using
tools or keys and must only be permitted to instructed or approved personnel.
1.6.2 Installation position and minimum distances
The module is suitable for mounting on a top-hat rail in any position. No minimum distances need to be
observed, but accessibility for connectors and the SD card must be ensured.
1.6.3 Electrical installation
The regionally applicable safety regulations must be observed.
1.6.4 Protection against electrostatic discharges
To prevent damage caused by electrostatic discharges, the following safety measures must be followed
during assembly and service work:
•Never place components and assemblies directly on plastic objects (e.g. polystyrene, PE film) and
also avoid their proximity.

ETHERLINE® GUARD | Issue 1e | 11.04.2022 8
•Use ESD-compliant tools and clothing.
•Do not touch components and assemblies at contacts.
1.6.5 EMC protection
In order to ensure electromagnetic compatibility (EMC) in your control cabinets and in an electrically
harsh environment, the known rules of EMC-compliant construction must be observed during design and
assembly. In particular, the functional earth (FE) connection must be connected to the potential
equalisation.
1.6.6 Operation
Only operate the unit when it is in technically perfect condition. The permissible operating conditions and
performance limits must be observed.
Retrofitting, modifications or conversions to the unit are strictly prohibited.
The unit is a piece of equipment for use in industrial installations. During operation, all covers on the unit
and the installation must be closed to ensure protection against accidental contact.

2 Security recommendations
ETHERLINE®GUARD is a network component and therefore an important element when considering
security aspects within a facility or network. Therefore, when using ETHERLINE® GUARD, observe the
following recommendations to prevent unauthorised access to installations and systems.
General:
•Ensure at regular intervals that all relevant components comply with these recommendations and,
if applicable, other internal safety guidelines.
•Evaluate your system holistically with regard to safety. Use a cell protection concept ("defence-in-
depth") with appropriate products.
•Keep yourself regularly informed about security threats to all your components.
Physical access:
•Restrict physical access to safety-related components to qualified personnel.
Security of the software:
•Keep the firmware and all communication components up to date at all times.
•Check regularly for firmware updates for the product.
•Only activate protocols and functions that you really need.
•Switch off accesses that are not required for operation after configuration
•Deactivate access options after configuration that are not required for continuous operation.
•If possible, always use those variants of protocols that offer more security.
Passwords:
•Define rules and roles for the use of the devices and the assignment of passwords.
•Change default passwords.
•Only use passwords with a high password strength.
•Ensure that all passwords are inaccessible to unauthorised personnel.
•Do not use the same password for different users and systems.
