required level of qualified service personnel according to safety standards.
Before energising and connecting communication cables to the product, ensure a
protective earthing conductor is first connected to the protective earthing
terminal (only valid for metallic housings). Westermo recommends a cross-
sectional area of at least 4 mm2.
Upon removal of the product, disconnect the product from the power supply and
all other communication ports before disconnecting the protective earthing
conductor.
⚠ HAZARDOUS VOLTAGE Do not open an energised product. Hazardous voltage may occur when connected to a power supply.
⚠ PROTECTIVE FUSE The power supply wiring must be sufficiently fused. It must be possible to disconnect manually from the power supply. Ensure compliance to national installation regulations. Replacing the internal fuse must only be performed by Westermo qualified personnel.
⚠ REDUCE THE RISK OF FIRE To reduce the risk of fire, use only telecommunication line cords with a cable diameter of AWG 26 or larger. Regarding power cable dimensions, see chapter Interface Specifications.
HOT SURFACE Be aware that the surface of this product may become hot. When it is operated at high temperatures, the external surface may exceed Touch Temperature Limit according to the product’s relevant electrical safety standard.
⚠ ELECTROSTATIC DISCHARGE (ESD) Prevent electrostatic discharge damage to internal electronic parts by discharging your body to a grounding point (e.g. use a wrist strap).
2.3. Care Recommendations
Follow the care recommendations below to maintain full operation of the product and to fulfill the warranty obligations:

3. Product Description
3.1. Product Description
The Viper-002-PL series consists of Ethernet extenders and bridges for
propagating Ethernet traffic over existing cabling. The series is based on
power line communication (G.hn) and is capable of bridging high bandwidth
Ethernet traffic over 2-wire cables, even when there are oxidized connectors.
By simply installing a Viper-002-PL product on each side of the coupler, a
bridge connecting the Ethernet networks on each side is created. The power
line technology allows using existing cables, which leads to significant
financial savings when refurbishing trains. The fact that no configuration is
needed further contributes to the ease of use.
The Viper-002-PL series has been thoroughly tested by certified labs to ensure
its compliance with the standard for electronic equipment used on rolling
stock, the EN 50155. For several characteristics, Westermo exceeds the
requirements mandated by the standard, e.g. by providing 1.5 kVrms insulation
on all ports.
Furthermore, the design is based on Westermo’s long experience within the
rolling stock market, which brings benefits such as vibration safe integrated
connector threading, IP67 ingress protection with GORE-TEX® membrane to
prevent condensation water build-up and ultimately a high MTBF and long
service life under the harshest conditions.
The Viper-002-PL series is built in Westermo’s Swedish factory which is
renowned for its extremely high standard, as confirmed by a multitude of
quality audits by demanding international customers. The factory is organized
according to lean manufacturing principles and it is equipped with
sophisticated state-of-the-art quality assurance equipment.
Meeting the requirements for rolling stock, makes the Viper-002-PL series also
very well suited for deployment in other applications with severe operating
conditions and extreme environments .
3.2. Available Models
3.2.1. Additional Model Information
In most cases, only the Viper-002-T1-PL1 model is used. In cases when two different Ethernet interfaces are used but only one transmission cable is present, different Viper-002-PL models can use same transmission cable without mixing Ethernet interfaces. The two models have different configurations which ensure that they will only connect to the same model and avoid crosstalk.

3.6. Dimensions
Dimensions are stated in mm and are regardless of model.
4. Installation
4.1. Wall Mounting
The product can be wall mounted vertically or horizontally. There are four pieces of 7 mm bores for this. Use four M5, M6 or 1/4″ screws with 12 mm washers on a flat and stable surface.
4.2. Protective Earth Connection
For correct function, the earth connection needs to be properly connected to a designated PE rail. Torx: T25 and torque: 3.2 Nm.
4.3. Connection of Cables
Recommended tightening torque for the M12 connectors is 0.6 Nm. When connecting the power cable, ensure that the pins are connected correctly before tightening the power cable to the unit.
⚠ PROTECTIVE FUSE The power supply wiring must be sufficiently fused.
It must be possible to disconnect manually from the power supply. Ensure
compliance to national installation regulations.
Replacing the internal fuse must only be performed by Westermo qualified
personnel.
ℹ NOTE – UNUSED CONNECTORS
Unused connectors must be covered by a protective cap (delivered with the
product), tightened to the specified torque in order to fulfil the specified
ingress protection code.
4.4. Cooling
This product relies on convection cooling. Make sure that it is installed so that the ambient temperature is within the specified temperature range. Avoid obstruction of the airflow around the product.
4.5. Replacement of Product
Disconnect all cables and unscrew the product from the wall. MTTR (Mean Time To Repair), i.e. time for replacement of product is < 10 minutes.
4.6. EN 45545-2 Mounting Notes
Two product can be mounted together and as a single interior non-listed group in the sense of EN 45545-2 definitions. For multiple product, the spacing requirements for interior non-listed groups must be met.
4.7. Getting Started
The product is easy to use and install. The units work in a pair over existing
cabling infrastructure and automatically connect to each other when the remote
device is sensed over the interconnecting lines.
The installation procedure to get the application up and running is simple.
- Connect the cable (twisted pair or parallell cable) to X2 pin 1 and 3 (polarity independent).
- Connect Ethernet to the X1 port on the front of the product.
- Connect power to the devices.
The following settings are valid for the Ethernet interface:
- Ethernet auto-negotiation enabled
- Auto MDI/MDI-X
- Auto-polarity enabled
The product will automatically detect the possible data rate to the remote
device (over the X2 – PLC interface ).
The link performance can easily be measured after the powerline link is
established. Different types of methods and tools can be used.
One example of recommended software for throughput testing is Iperf. Please
refer to Iperf user documentation for instructions of usage.
ℹ NOTE
If the PLC link is not established or the established data rate is not
sufficient for the application, the distance might be too long between the
products.
The product is an unmanaged unit. If performance is low or no connection established, check cabling between the product.
4.8. Configuration
All necessary configurations are preconfigured from factory and no other changes in the settings can be done.
