63. INSTALLATION3.1. Placement and mountingThe amplifier is presented as a 2 unit high 19'' rack module. It is supplied with plastic washers inorder not to damage the unit when tightening the screws.Always fix the amplifier to a 19” rack through the front ears using all corners and four screws.For portable, mobile, or other applications where the rack assembly may be moved, we recommendsupporting the rear of the amplifier using support rails.It is very important not to enclose the amplifier or expose it to extreme temperatures as itgenerates heat. It’s also necessary to promote the passage of fresh air through the ventilationholes of the chassis, leaving at least one rack unit off between each device and installed aboveand below it in the rack frame.If the setup has several amplifiers in the same rack or in a closed cabinet with doors, it is highlyrecommended to supply them forced ventilation, installing fans at the upper and lower ends. This upwardair flow will help to dissipate the heat generated inside.In order to optimize as much as possible the correct thermal dissipation of equipment installed ina closed rack, it is advisable not to place power amplifiers under other appliances, but upon these ones.3.2. Mains connectionThe amplifier operates on alternate currents, depending on the country 110-120, 220-240V50/60Hz (see characteristics in the back of the unit). The power consumption at maximum performanceis 340VA for the MPA4-150R and 510VA for the MPA6-150R. It's important that your mains installation isadequately rated to these power demands.The amplifier should have an earth connection in good conditions (earth resistance, Rg=30Ω orless). The environment must be dry and dustless. Do not expose the unit to rain or water splashes, anddo not place liquid containers or incandescent objects like candles on top of the unit. Do not obstruct theventilation grids with any kind of material.In case there is some type of intervention and/or connection-disconnection of the amplifier, it is mostimportant to previously disconnect the mains power supply. There are no user or serviceable parts insidethe amplifier.You should avoid that the supply cable twists with the shielded signal cables, as this could lead tounwanted hum.In order to protect the unit from an eventual electrical overload or momentary power peaks fromthe internal circuits it carries a fuse. Should it ever blow up, unplug the unit from mains and replace itwith an identical one. If the new fuse blows again contact immediately with our Authorized TechnicalService.CAUTION: YOU MUST NEVER USE A HIGHER VALUE FUSE.
