Under no circumstances shall Westermo be responsible for any loss of data or income or any special, incidental, and consequential or indirect damages howsoever caused.
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.
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.

RS-485 termination at system level The system should be installed in according to the RS-485 specification. A system should always form a bus structure where the termination is at the end points of the bus. See diagrams for details of how this is done with RS-485 2-wire and 4-wire. R–...
About the interfaces Power terminal The power terminal has two independent inputs, +VA and +VB, allowing redundancy should either fail. The ODW-730 power supply is galvanically isolated from all other internal electronics. Optical fibre interfaces ODW-730 uses Small From Factor Pluggable (SFP) transceivers that are in compliance with the Multi-Sourcing Agreement (MSA).

Mounting This unit should be mounted on 35 mm DIN-rail, which is horizontally mounted inside an apparatus cabinet, or similar. Snap on mounting, see figure. Cooling 10 mm * (0.4 inches) This unit uses convection cooling. To avoid obstructing the 25 mm airflow around the unit, use the following spacing rules.
