User manual QSC AUDIO IT-8400 INSTALLATION

[. . . ] This limited warranty is freely transferable during the term of the warranty period. The warranty on QSC products is NOT VALID if the products have been purchased from an unauthorized dealer/online e-tailer, or if the original factory serial number has been removed, defaced, or replaced in any way. Damage to, or loss of any software or data residing on the product is not covered. When providing repair or replacement service, QSC will use reasonable efforts to reinstall the product's original software configuration and subsequent update releases, but will not provide any recovery or transfer of software or data contained on the serviced unit not originally included in the product. [. . . ] Be sure to properly recycle the carton and the packing materials. Handles Install the optional handles to the front of the panel using the screws provided. EN 3 Rack Mounting The IT-8400 includes several mounting holes for installation into any standard 19" rack. Install the IT-8400 in the rack with at least two screws (not provided) on each side of the panel. The panel includes additional holes to allow it to be mounted at half-rack-space intervals to allow for wire routing between components. If the rack has rear rails, you may find it more convenient to install the accessory behind the amplifiers to simplify wire routing. If you are using more than one IT-8400 in the same rack, separate them by at least one rack space to minimize crosstalk. CAUTION: Turn off the amplifiers before wiring up the accessory. EN 4 Configuration Each channel of the IT-8400 is factory set to the 100 volt configuration. To change the configuration for any channel, access the wire connections on the back side of the panel. Make changes to the wiring configuration before installing the accessory into the rack. The center section of printed circuit board contains text that identifies the channel numbers and terminal voltages alongside the associated wire connection points. Also refer to the figures below. 100 VOLT LINE Connect the blue wire to the terminal marked 0V. Connect the orange wire to the terminal marked NOT USED. 70 VOLT LINE Connect the blue wire to the terminal marked 0V. Connect the yellow wire to the terminal marked NOT USED. EN 25 VOLT LINE Connect the orange wire to the terminal marked 0V. Amplifier settings: To minimize transformer saturation, use the amplifier's 75 Hz input filters. See the CX302 user's manual for instructions on configuring filters and clip limiters. B = Blue O = Orange Y = Yellow Connecting the amplifier to the IT-8400 accessory Turn off the amplifier before opening the safety shroud over the output barrier strip or making any changes to the output connections. Always close the safety shroud when you finish working on the output connections and before turning the amplifier on. Use fully insulated wiring that conforms with local and national electrical and safety codes. Class 2 wiring for this application is specified by the 1999 National Electrical Code, which is prevalent in the United States. These plugs are made to accept wire sizes from 24 AWG (0. 2 mm2) to 10 AWG (6 mm2). [. . . ] Refer to the label on the panel for channel and voltage assignments. EN Note: 25V distribution lines will connect between the terminals marked 0 and 70V/100V. The transformer wiring must be configured for 25V on each channel prior to connection to 25V distribution lines. The plugs install into the accessory with the terminal screws oriented down. The plugs for the distributed lines are installed into the connectors labeled OUTPUT TO SPEAKERS. [. . . ]
