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 (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 waterproof. 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 distributor 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.

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.
