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 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.

Class 1 Laser Product

Do not look directly into fibre optical fibre port or any connected fibre although
this unit is designed to meet the Class 1 Laser regulations.

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.
Fibre connectors are supplied with plugs to avoid contamination inside the optical port.
As long as no optical fibre is mounted on the connector, e.g. for storage, service or

transportation, should the plug be applied.

Note. Fibre Optic Handling

Fibre optic equipment needs special treatment. It is very sensitive to dust and dirt. If
the fibre will be disconnected from the modem the protective hood on the transmitter/
receiver must be connected. The protective hood must be kept on during transportation.
The fibre optic cable must also be handle the same way.

If this recommendation not will be followed it can jeopardise the warranty.

Cleaning of the optical connectors

In the event of contamination, the optical connectors should be cleaned by the use of
forced nitrogen and some kind of cleaning stick.

Recommended cleaning fluids:

• Methyl-, ethyl-, isopropyl- or isobutyl-alcohol

• Hexane

• Naphtha

Maintenance

No maintenance is required, as long as the unit is used as intended within the specified
conditions.

Product disposal

This symbol means that the product shall not be treated as
unsorted municipal waste when disposing of it. It needs to
be handed over to an applicable collection point for recy­cling electrical and electronic equipment.

Description

The LRW-102 (LRW-102PP) offers an easy way to extend the distance between

LonWorks® 78 kbit/s TP/FT network segments using a fibre optic link.

The LRW-102PP is a fibre optic modem used for point-to-point applications and the
LRW-102 is used for multidrop and redundant ring applications. It acts as a repeater
between the two fibre optic links, and as a converter between fibre optical links and
the LON TP/FT port. The maximum distance of the fibre links depends on selected
transceiver and fibre types.

The LRW-102 (LRW-102PP) is designed for harsh outdoor usage, in industrial, road or
railway installations. The complete transparent conversion to and from the fibre optic
media facilitates the installation procedure by eliminating the need for any additional
network addressing or software configuration.

Functional description

Converter TP/FT interface – optical fibre

The LRW-102 (LRW-102PP) is a fibre optic converter that converts between

LonWorks® TP/FT, and fibre optical link.

Repeater – optical fibre links

The LRW-102 is a fibre optic repeater that repeats received data from one fibre
link out to the other link. This is useful e.g. for long distance communication, where
electromagnetic interference may occur or when isolation of the electrical network is
needed.

Single or multimode LC fibre connectors

The LRW-102 (LRW-102PP) uses Small Form Factor Pluggable (SFP) transceivers that
are in compliance with Multi-Sourcing Agreement (MSA). A wide range of different fibre
transceivers and connectors can be used.
