8 PLM Series Quick Start and Field Reference Guide5 INsTAllATONPLMs on the same aC mains circuit to be poweredup simultaneously.5.6 Groundinganalog inputs feature iso-Float™ ground isolationcombining the benefits of transformer-coupled isola-tion with the advantages of clean, direct-coupledinputs.the audio converters are galvanically isolated, andnot connected to the main ground. High-speedtransformers and opto-isolators create a barrierbetween the PLM Series and the outside electricalenvironment.the iso-Float feature is activated by default,butmay be disabled via the supplied Dolby LakeController PLM Edition software, or via thePLM’s front panel menu system.in the interests of safety, nEVER disconnect the earth(ground) pin on the mains cable (aC power cord).use correctly-shielded balanced audio input con-nections to minimize hum and interference. Refer tosection 10.2.1 of the PLM Series operation Manualfor more information.5.5 Operating Voltagethe label adjacent to the mains (aC) input con-nector indicates the aC mains voltage for whichyour PLM is wired and approved. the PLM Series isavailable in two versions: 115 V and 230 V. Connectthe mains cable (aC cord) only to an aC source ofthe voltage shown on the label.any damage resulting from a PLM Seriesproduct being connected to an aC source ofincorrect voltage will not be covered by thewarranty.the PLM uses primary switching, which means themains power is rectified on the primary side of thetransformer. this makes the power supply insen-sitive to mains frequency variation, and it will operatenormally on line frequencies from 45 to 75 Hz.if the mains plug (aC plug) fitted to the mains cable(aC cord) is not appropriate for your country, it canbe removed and a locally-sourced one fitted instead,observing the following color coding:PowerCon Pin 230 V Version 115 V VersionL Brown BlackN Blue WhiteGreen/Yellow GreenTable 5.5: AC plug configurationif you are not 100% confident of your compe-tence to replace the mains plug (aC plug), thetask should be carried out by qualified personnel.once a suitable aC supply is connected, the PLMcan be turned on using the front panel power switch.When the unit is switched on, the PLM goes througha soft-start sequence as it performs a diagnosticroutine on the internal circuitry. the fans will run athigh speed for a short period before dropping to idlespeed, and the power symbol in the power switch willchange from red (Standby mode) to green (active).in-rush current is controlled and limited duringthe soft-start sequence, enabling multiple
