Installation of Lopolight Navigation Lights This document is a recommendation on installation of Lopolight navigation lights based on best practices and learnings from over 50.000 lights installed. The reason for issuing this document is that we are replacing a high current., high maintenance incandescent light with a low current, sophisticated piece of electronics. In retrofit situations where existing installations has been used this has led to some unexpected and inconvenient results. Lopolight general specifications: Current draw: from 50mA to 900mA (lowest on sidelights ana highest on masthead lights) Due to the very low power consumption and sometimes very long cable runs the Lopolights can be damaged by excess induction from high current cables and devices in the proximity of the cable. Transients from various unprotected equipment can also pose a threat to the lights, the built-in protective components deals with most transients up to +/- 800V @ 1ms, but stronger and longer transients will damage the light. The Lopolight products in the 2011 versions will be delivered with screened cable, this screen is not The standard cable lengths are: Sidelights, combined sidelights and stern lights: 2,5 meters Tricolours, 360" lights, masthead lights: 0,7 meters All lights with an aluminium mounting base or back, such as 3 nm horizontal mount lights and all 5 and 6 nm masthead light are not delivered with any cable. It is strongly recommended that the complete installation is done with screened cable, correctly spliced to the Lopolight cable and the screen terminated to the grounding point of the vessel. Lopolight can supply the lights with any length of cable needed. The power supply should come from a regulated source that blocks transients from reaching the If screened cable or regulated power supply cannot be established Lopolight has a transient filter that can urovorl transo'ÍK and irdjaxJ Vcl'.ago ci rs:a;:'iii'g II'Ì: igni. ^/N ¿00 026 Recommended installations: A) Regulated power supply and screened cable, as described above. B) Filters in front of each light, the distance from the filter to the light should not exceed 2,5 C) For small vessels where the issue is the power supply and the cable runs are short and not endangered by induction, one filter can be used for the complete navigation light installation, placed before :ne ú strioution panel.

The Lopolight Transient Filter is to be fitted before any Lopolight (or other electrical device) on installations where heavy transients are expected. Physical mounting: t should be --.cunted "in-li-ie" as c ose as pract cal aassible to tne device that needs profeciion. Typically 1 -2 meters as maximum. Working principle: The transient filter allows any voltage under 32 VDC to pass, but efficiently blocks any voltage spike above this level. Potted construction - submersible Connections: Flying leads Output (to light|: Orange: 10-32VDC Installation recommendations: Evaluate where transients...
