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 (e.g. Littlefuse 0461 1.25), and
if necessary it must be possible to disconnect manually from the power supply. If
fault contact is used, make sure that fault contact wiring is sufficiently fused.
This unit uses convection cooling. To avoid obstructing the airflow around the unit,
follow the spacing recommendations (see Cooling section).
Before mounting, using or removing this unit:
Prevent access to hazardous voltage by disconnecting the unit from power supply.
Warning! Do not open connected unit. Hazardous voltage may occur within this
unit when connected to power supply.
Care recommendations
Follow the care recommendations below to maintain full operation of unit and to fulfil
the warranty obligations.
This unit must not be operating with removed covers or lids.
Do not attempt to disassemble the unit. There are no user serviceable parts inside.
Do not drop, knock or shake the unit, rough handling above the specification may cause
damage to internal circuit boards.
Do not use harsh chemicals, cleaning solvents or strong detergents to clean the unit.
Do not paint the unit. Paint can clog the unit and prevent proper operation.
Do not expose the unit to any kind of liquids (rain, beverages, etc). The unit is not water-
proof. Keep the unit within the specified humidity levels.
Do not use or store the unit in dusty, dirty areas, connectors as well as other mechanical
part may be damaged.
If the unit is not working properly, contact the place of purchase, nearest Westermo dis-
tributor office or Westermo Tech support.
Do not cover or bring mechanical force to the ventilation membrane on the back of the
unit.
Maintenance
No maintenance is required, as long as the unit is used as intended within the specified
conditions.

This equipment has been tested and found to comply with the limits for a
Class B digital device, pursuant to Part 15 of the FCC Rules. These limits
are designed to provide reasonable protection against harmful interference
in a residential installation. This equipment generates, uses and can radiate
radio frequency energy and, if not installed and used in accordance with
the instructions, may cause harmful interference to radio communications.
However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio
or television reception, which can be determined by turning the equipment
off and on, the user is encouraged to try to correct the interference by
one or more of the following measures:
… Reorient or relocate the receiving antenna
… Increase the separation between the equipment and receiver
… Connect the equipment into an outlet on a circuit different from that to
which the receiver is connected
… Consult the dealer or an experienced radio/TV technician for help.

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.
