User manual ELECTRO-VOICE CPS2.4

[. . . ] The lightning flash with arrowhead symbol, within an equilateral triangle is intended to alert the user to the presence of uninsulated , , dangerous voltage" within the product's enclosure that may be of sufficent magnitude to constitute a risk of electric shock to persons. Do not install near heat sources such as radiators, heat registers, stoves, or other apparatus (including amplifiers) that produce heat. Do not defeat the safety purpose of the polarized or the grounding-type plug. I the provided plug does not fit into your outlet, consult an electrician for replacement of the obsolete outlet. [. . . ] The Mains Switch on the front panel separates the power amp from the mains. A soft start circuit compensates mains inrush current peaks and thus prevents triggering AC mains fuse when switching on the amplifier. Speaker system switch-on is delayed by approximately 2 seconds via output relays, effectively suppressing any possible power-on noise, which otherwise might be heard through the loudspeakers. Attach the power amp with its frontal rack mount ears using 4 screws and washers as shown in following illustration. Additionally securing the amplifier at the rear becomes necessary, if the rack case in which the power amplifier has been installed will be transported. Failure to do so may result in damage to the power amplifier as well as to the rack case. Attach the power amp as shown in the illustration using 4 case nuts and screws. Brackets for securing the power amplifier are available as accessories. As with all Electro-Voice power amps with fan cooling, the airflow direction is frontto-rear, obviously because there is more cold air outside of the rack case than inside. The power amplifier remains cooler and dissipating the developing waste heat in a specific direction gets easier. In general, setting up or mounting the power amplifier has to be done in a way that fresh air can enter unhindered at the front and exhausted air can exit at the rear. When installing the power amp in a case or rack system, attention should be paid to these details to provide sufficient ventilation. Allow for an air duct of at least 60 mm x 330 mm between the rear panel of the power amplifier and the inner wall of the cabinet/rack case. make sure that the duct reaches up to the cabinet's or the rack case's top ventilation louvers. Leave room of at least 100 mm above the cabinet/rack case for ventilation. Since temperatures inside of the cabinet/ rack case can easily rise up to 40 °C during operation of the power amp, it is mandatory to bear in mind the maximum allowable ambient temperature for all other appliances installed in the same cabinet/rack case. CAUTION: Blocking/closing the power amp's ventilation louvers is not permissible. Without sufficient cooling/ventilation, the power amplifier may automatically enter protect mode. Do not use the power amplifier near heat sources, like heater blowers, stoves or any other heat radiating devices. To ensure trouble-free operation, make certain that the maximum allowable ambient temperature of +40°C is not exceeded. For fixed amplifier installations in a device control room that incorporate a central air-cooling system or air conditioners, calculating the maximum heat emission may be necessary. When operating the power amplifier together with other equipment in a rack case, setting the switch to the GROUNDED position is recommended. [. . . ] The LOW selector switch sets the lower digit, while HIGH sets the higher digit. Address 0 (00 hex, delivery status) disables remote communication between the RCM-810 and the bus. The module does not appear in the system, even though it is physically connected to the CAN-bus. 2 STATUS LED The STATUS-LED is for monitoring the communication on the CAN bus. [. . . ]
