Rack mountable Yes Power requirements 115 VAC or 230 VAC 10 50 60 Hz operating voltage is factory configured Power consumption approximately 10 watts at high speed Page 3 Installation and Configuration How the Sherbourn C 12 operates is determined both by switch settings and by mechanical reconfiguration of parts of the device Read and follow the instructions carefully Improper or incomplete configuration may result in unusual or unexpected behavior In general the electrical configuration and switch settings determine when and if the C 12 fans will operate and at what speed while the mechanical configuration determines the direction of air flow through the unit when the fans are active Note The Trigger In connector on the C 12 is a switched connector Connecting a cable to this input operates a switch inside the C 12 so plugging in a cable that is not connected to an appropriate device at the other end may result in improper operation of the C 12 The Trigger In connection also serves different purposes depending on how the Trigger Mode switch is set Note The Trigger Out connector carries different signal levels depending on how the Trigger Mode switch is set Specifically when the Trigger Mode switch is in the Sync position the Trigger Out should NOT be used to trigger ordinary 12 V triggered devices Front panel Power Switch On Auto on the left side of the front panel This is a mech
