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 in to an apparatus cabinet or similar, where access is restricted to service personnel only. 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.
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. 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 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 damages 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 full operation of product and to fulfill the warranty obligations:
- Do not drop, knock or shake the product. Rough handling above the specification may cause damage to internal circuit boards.
- Use a dry or slightly water-damp cloth to clean the product. Do not use harsh chemicals, cleaning solvents or strong detergents.
- Do not paint the product. Paint can clog the product and prevent proper operation.
If the product is used in a manner not according to specification, the protection provided by the equipment may be impaired. If the product is not working properly, contact the place of purchase, nearest Westermo distributor office or Westermo technical support.

FCC Part 15.105 Notice:
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 inter-ference to radio communications. However, there is no guarantee that interference will not occur in a partic ular 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.
