Safety
Before installation:
Read this manual completely and gather all information on the unit. Make sure
that you understand it fully. Check that your application does not exceed the safe
operating specifications for this unit.
This unit should only be installed by qualified personnel.
This unit should be built-in to an apparatus cabinet, or similar, where access is
restricted to service personnel only. The power supply wiring must be sufficiently
fused, and if necessary it must be possible to disconnect manually from all power
supply. Ensure compliance to national installation regulations. This unit relies on
convection cooling. Make sure that it is installed so that the ambient temperature
is within the specified temperature range, e.g. by avoiding obstruction of the
airflow around the unit. Also check chapter EN 45545-2 mounting notes.
The unit has no internal fuse and should be connected via an external fuse. The
fuse should be calculated in accordance with the rated current.
Before mounting, using or removing this unit:
Prevent access to hazardous voltage by disconnecting the unit from all power supply.
WARNING
Do not open connected unit. Hazardous voltage may occur within this unit when
connected to power supply.
Before powering-up, a protective earthing conductor must be connected to the
protective earthing terminal and have a cross-sectional area of at least 1.5 mm².
Note that this unit can be connected to two different power sources.
Be aware of that the surface of this unit may become hot. When this unit is
operated at high temperatures, the External Surface of Equipment may exceed
Touch Temperature Limit according to EN/IEC/UL 60950-1.
To reduce the risk of fire:
1. Use only No. 21 AWG or larger power cable
2. Use only No. 26 AWG or larger telecommunication line cord.

Description
Functional description
Viper 008 is a unmanaged switch developed for rail and industrial applications. To meet
the environmental requirements from rail and harsh industrial applications the switch
has rugged M12 Ethernet connectors and full metal housing. The IP65 sealed metal case
make it robust and allows for the surrounding air temperature to be between –40 to
+70°C. There are no sensitive or fragile components, hardening the product against
shock and vibration making these units suitable for rolling stock usage. The power supply
operates over a wide input range from 24 to 110 VDC.

Fault Contact
The Viper switch is equipped with a potential free normally closed fault contact. The
fault contact is a solid state component (relay) that requires power to work and it is
transient protected. Additionally, the fault contact is opened when any of the following
conditions is met:
• No voltage on the power supply pin, a voltage level outside the legal voltage range
or current limitation on the voltage source is applied on the power input.
Description of how connection to the fault contact could be done is shown below. The
relay is closed when the unit is OK and open at failure. The relay is of semiconductor
type (no moving parts). It is specified for max current 250 mA continuous, 500 mA
peak (10 ms), operational voltage up to 110 V, protected by a 150 VDC-varistor,
ON-resistance less than 10 Ohm, and leakage current max 1 µA.
