NE1100A2 CATV Optical Receiver Operation Manual
9.0 Closing the Outer Cover.
The receiver housing must be kept airtight to prevent moisture in the air from affecting the
performance and the life of the optical receiver.
Before closing the outer cover verify the following:
1. Verify that the receiver chassis is securely fastened to the receiver housing with the (3)
captive screws (see fig. 5).
2. Verify that the top panel is fastened shut with (2) screws (see fig. 5).
3. Make sure there is no dust or debris on the gasket seal. Clean the gasket surface if
necessary. After each cleaning or after several years of use, an application of silicon
grease to the gasket seal is recommended to keep the seal airtight.
4. While closing the receiver housing, make sure that the wiring harnesses from either side
of the DC power supply are folded into the openings on both sides of the DC power
supply. Do not allow the wiring to be caught between the power supply and the horizontal
edge of the receiver housing. Make sure that neither the power supply wiring or optical
fiber cable are caught between the upper and lower halves of the receiver housing.
5. Make sure that the (4) waterproof connectors and/or and plugs are tightly installed at
all 4 ports A, B, C, & D.
6. Completely tighten the (6) captive screws attaching the upper and lower halves of the
weatherproof receiver housing.
