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.
Branch circuit protection (fuse) is required for this unit with rating not
exceeding 20 A.
Product should be connected to UL Listed power supplies rated 12 – 48 VDC,
min 500 mA or 24 VAC, min 500 mA or reliably grounded DC SELV source*.
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 fibre 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.
* Applicable for ODW-720-F1 only
6651-2221

Note. Fibre Optic Handling
Fibre optic equipment requires careful handling as the fibre components are very
sensitive to dust and dirt. If the fibre is disconnected from the modem, the protective
plug on the transmitter/receiver must be replaced. The protective plug must be kept on
during transportation. The fibre optic cable must also be protected in the same way.
If this recommendation is not followed, it can jeopardise the warranty.
Cleaning of the optical connectors
In the event of contamination, the optical connectors should be cleaned by using 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.

Notice:
EN 55022 Notice:
This equipment has been tested and found to comply with the limits for a Class A
digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide
reasonable protection against harmful interference when the equipment is operated in a
commercial environment.
This equipment generates, uses, and can radiate radio frequency energy and, if not
installed and used in accordance with the instruction manual, may cause harmful interference to radio communications. Operation of this equipment in a residential area is likely
to cause harmful interference in which case the user will be required to correct the
interference at his own expense.
This is a class A product. In a domestic environment this product may cause radio interference in which case the user may be required to take adequate measures.

Before DIP-switch settings:
Prevent damage to internal electronics from electrostatic discharges (ESD) by
discharging your body to a grounding point (e.g. use of wrist strap)
Note: Disconnect power before DIP-switch settings.

The ODW-720-F1 DIP-switches are pre-set from the factory, so that the unit can be
used for point-to-point applications, togheter with an additional ODW-720-F1, straight
out of the box, without the need for any type of user configuration.
The only choise required, is if to enable the RTS to CTS signalling function or not.
See the DIP-switch S2:1 description below.
If the ODW-720-F1 is to be used in a multidrop network togheter with ODW-720-F2

About the interfaces
Power
The power terminal has two independent inputs, +VA and +VB, allowing redundant
power input.
The ODW-720-F1 power supply is galvanically isolated from all other interfaces.
Optical fibre interfaces
ODW-720-F1 uses Small Form Factor Pluggable (SFP) transceivers. This means that a
wide range of different fibre transceivers and connectors can be used (see page 12–13).
RS-232 interface
The RS-232 interface is a female 9-position D-sub. Pin assignments are compliance with
the EIA RS-232 standard.
Status port
The status port connects to an internal relay witch may be used to trigger an external
alarm if a fault condition occurs. During normal operation pins 1 and 2 are in contact
with each other, and pins 2 and 3 are isolated. During an optical link failure, or power
failure, pins 1 and 2 are isolated, and pins 2 and 3 are in contact with each other.
