Power Input - HiperMAX

Each SCRT is provided with a 48 volt power cable terminated with a female connector at the SCRT end and bare wires at the other. The termination details for the -48v supply are shown in the relevant installation manual.

Important Note: The female connector attaches to the SCRT and the male connector attaches to the SDR-micro. It is important that the power connector is attached at the correct end. See illustration below or damage to the connector/equipment will result.

Optic Interface

When running cables care should be taken not to exceed a force of 800N on the cable or connector. Do not kink cable or bend over sharp edges.

Each SCRT is connected with an optical fibre cable, ready terminated with  optical connectors. Unscrew the protective dust cap and screw the fibre optic cable in place. Only remove the cap prior to installation and never leave the optical interface open without a protection cap.

Tighten to 1Nm using a calibrated torque wrench. Never exceed 2Nm as the optical interface may be damaged causing excess losses

Antenna RF Port

RF feeder connector: N-Type Female: Impedance: 50ohms: Minimum In-band Return Loss:15dB.

Protective Earth Connection

A screw terminal is provided on the SCRT for bonding the SCRT to a protective earth.
