NJR2935 series 7. Handling Precautions 7.1. DANGER This statement indicates an imminently hazardous situation which, if not avoided, will result in death or serious injury. Items Description Input Voltage Only input a DC voltage within the range indicated in specifications. - Page 13 NJR2935 series Items Description Weatherproof The unit mounted in outdoor should be conducted with adequately weatherproof procedure. Do seal all of cable connection points from the connector to the cable sheath by usage of self-amalgamating tape. Ensure the waveguide connection is properly assembled with the supplied o-ring gasket as accessories.
- Page 14 NJR2935 series 8. Instructions Manual 8.1. Descriptions This section describes the information of connectors and etc. Items Description Purpose RF Input Waveguide: WR-75 The LNB receives an RF signal (Ku-band: frequency Waveguide Flange: Square Cover divided by region band from the 10.75 to 12.75 GHz) via Grooved this waveguide.
- Page 15 NJR2935 series 8.2.1. Mounting Configuration The Unit can be mounted with OMT or the waveguide filter of the satellite antenna. When mounting with the OMT or the waveguide filter, the following steps should be complied: Step 1: Verify that the groove on the waveguide flange for a gasket is clean.
