Page 16: Status Port
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. RS-232 interface The RS-232 interface is a female 9-position D-sub. - Page 17 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 air- 25 mm flow around the unit, use the following spacing rules.
