Before Installation

Read this manual completely and gather all information on the product. Make sure that you understand it fully. Check that your application does not exceed the safe operating specifications for this product.

SAFETY DURING INSTALLATION
The product must be installed by qualified service personnel and built into an apparatus cabinet or similar, where access is restricted to service personnel only.
Refer to Compliance Information to see the required level of qualified service personnel according to safety standards.
During installation, 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, ensure that the protective earthing conductor is disconnected last.

HAZARDOUS VOLTAGE
Do not open an energized product. Hazardous voltage may occur when connected to a power supply.

PROTECTIVE FUSE
The power supply wiring must be sufficiently fused. The fuse must be IEC 60127 certified and rated for T1.25 A and 250 V.
It must be possible to disconnect manually from the power supply.
Ensure compliance with national installation regulations.
This product has no internal fuse and should be connected via an external fuse for protection.

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 the 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).

Care Recommendations

Follow the care recommendations below to maintain the full operation of the product and to fulfil the warranty obligations:

Do not drop, knock or shake the product. Rough handling above the specification may cause damage to internal circuit boards.

Description

Viper 008 is an 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 makes 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 are 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 to the power input. A description of how the 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.
