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 the power supply. Ensure compliance to 
national installation regulations.
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 voltages by disconnecting the unit from the power 
supply.
Warning! Do not open a connected unit. Hazardous voltages may occur within 
this unit when connected to a power supply.

Class 1 Laser Product

This unit is designed to meet the Class 1 Laser regulations. However, the user is 
warned not to look directly into fibre optical port or any connected fibre.

Care recommendations

Follow the care recommendations below to maintain full operation of the unit and to 
fulfil the warranty obligations.
This unit must not be operated with covers or lids removed.
Do not attempt to disassemble the unit. There are no user serviceable parts inside.
Do not drop, knock or shake the unit. Rough handling beyond 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 parts may be damaged.
If the unit is not working properly, contact the place of purchase, nearest Westermo  
distributor office, or Westermo Tech support.
Fibre connectors are supplied with plugs to avoid contamination inside the optical port.
The plug should be fitted when no optical fibre is inserted in the connector, e.g. during 
storage, service or transportation.
