  • Page 9: About This Manual

    About this Manual This manual provides installation and operation information for the Comtech EF Data LCS-4 L-Band Combiner Switch. This is a technical document intended for earth station engineers, technicians, and operators responsible for the operation and maintenance of the LCS-4.
  • Page 10 2.9 amps. USES The LCS-4 is fitted with two fuses, one each for line and neutral connections. These are contained within the body of the IEC power connector, behind a small plastic flap. For 115 and 130 volt AC operation, use T3, 15A, TO.75A, 20mm fuses.
  • Page 11 The installation and connection to the line supply must be made in compliance to local or national wiring codes and regulations. The LCS-4 is designed for connection to a power system that has separate ground, line and neutral conductors. The equipment is not designed for connection to power system that has no direct connection to ground.
  • Page 12 Preface MN/LCS4.IOM EMC (Electromagnetic Compatibility) In accordance with European Directive 89/336/EEC, the LCS-4 has been shown, by independent testing, to comply with the following standards: Emissions: EN 55022 Class B - Limits and methods of measurement of radio interference characteristics of Information Technology Equipment.

  • Page 13: Warranty Policy

    24 months from the date of shipment. During the warranty period, Comtech EF Data will, at its option, repair or replace products that prove to be defective. For equipment under warranty, the customer is responsible for freight to Comtech EF Data and all related custom, taxes, tariffs, insurance, etc.

    If other user equipment is utilized, the customer shall obtain the documentation required to operate with the LCS-4 L-Band Combiner Switch. IMPORTANT The LCS-4 L-Band Combiner Switch has a 4-way transmit (TX) and Receive (RX) path combiner/splitter. • Combines four TX L-Band signals from L-Band modulators for delivery to an Outdoor Unit (ODU) or Block Up Converter (BUC).
