80Application GuidePLM Series Operation Manual rev 1.1.910. Application GuideThis chapter describes the practical application and use of PLM Series devices.10.1 Rack I/O PanelsFor fast and simple system connection, pre-wired racks using connection panels can be used. With anI/O connector panel fitted to the front of the rack, all audio, loudspeaker, network and power cables can beplugged in at one position, without requiring rear panel access.Although rental companies and large system users may have existing preferred designs, Figure 10-1 pro-vides a suggested layout. This example provides AES/EBU and analog audio connections; a separate panelwould be used for Ethernet connections.Figure 10-1: Example I/O Connector Panel10.2 Power DistributionFor professional applications it is recommend that the sum of the available mains power is above 3000 Wper PLM (e.g. 230 V x 16 A, 120 V x 32 A). As PLM Series devices are equipped with PAL, the power supplywill limit its mains current draw (both momentary current draw and current draw over time) to be less than28 A for the 230 V version and less than 53 A for the 115 V version.Safety approved equipment is not required to have a mains breaker, as long as this does not pose any firehazard under fault conditions, as is the case with the PLM.Please see the following examples suggesting power distribution methods across multiple PLM devices.All of the examples given will work, although the first examples for both 230 V and 115 V operation have aslight advantage due to their “power sharing” ability.10.2.1 Six PLM Series Devices with 230-240 V Mains SupplyIf the mains supply is 230 V and the system requirement is six PLMs, then the mains capacity would needto be able to provide 3 x 32 A. There are two methods of achieving this:
