User manual MIDAS CONSOLES V190 PSU

[. . . ] Do not defeat the safety purpose of the polarized or grounding-type plug. A polarized plug has two blades with one wider than the other. A grounding type plug has two blades and a third grounding prong. The wide blade or the third prong are provided for your safety. [. . . ] The mains inlet is provided via a single IEC type socket. A mains cables is supplied with the unit. Never, under any circumstances, should the power supply be operated without it's safety earth connection. The V190 series power supply should be installed into a 19" rackmount enclosure. If the power supplies are not in a permanent installation, the rackmount enclosure construction should take into account the weight of the supply to prevent damage to either the power supply or enclosure while in transit. Air Flow The V190 power supply has a forced air cooling channel flowing from back to front. To maintain adequate ventilation to the unit, the cooling channel must not be blocked or hindered and one unit (1U) should be left free between the top of the power supply and any other equipment or the rack. The rackmount enclosure should allow adequate airflow to both the front and back panels of the power supply. If using a number of power supplies, one unit (1U) space should be left free above each supply. 0 I Front Power Low Mains +48V +12V _ 18V +18V PUSH DC Output / Link RISK OF ELECTRIC SHOCK DO NOT OPEN CAUTION CHECK VOLTAGE SELECTOR BEFORE APPLYING MAINS.

OPERATION IS SUBJECT TO THE FOLLOWING CONDITIONS: (1) THIS DEVICE MAY NOT CAUSE HARMFUL INTERFERENCE, AND (2) THIS DEVICE MUST ACCEPT ANY INTERFERENCE RECEIVED, INCLUDING INTERFERENCE THAT MAY CAUSE UNDESIRED OPERATION. 100V/120V/220V/240V AC~50-60Hz 520W SUPPLY VOLTAGE FUSE: 5x20mm T5A L250V Interference Some interference may be noticed when the power supply is situated in close proximity to the Verona console. Moving the power supply away from the console will rectify this problem. Service The power supply may only be serviced by authorised personnel. Refer all servicing to a qualified, approved Midas service agent. Depending upon where the power supply is installed, the interior of the unit will become, over time, dirty and will require cleaning. The power supply should also be serviced if it is dropped, exposed to rain or moisture, liquid has been spilled into the supply or if the unit ceases to function normally. DO NOT REMOVE THE COVER The inside of the power supply contains potentially lethal voltages and is capable of providing high currents. To reduce the possibility of electric shock, do not open the cover to the power supply. High voltages are still present in the supply, even when isolated from the mains. Operators Manual - Page 1 Connection and Operation Connection Before powering up the V190 power supply, connect either the front or rear power supply output to the power inlet socket on the console. The V190 power supply provides: PUSH Pin 1 Pin 2 Pin 3 Pin 4 Pin 5 Pin 6 - 0VA + 18V _ 18V + 12V + 48V 0VL +12 volts ±18 volts + 48 volts DC Output / Link The power supply should only be connected to the console using the provided power connection cable. If, for any reason, the power connection cable should become damaged, the cable should be serviced by an authorised Midas service agent immediately or a Midas authorised replacement sought. WARNING: The V190 power supply is capable of providing high currents. A short-circuit on any of the voltage supply pins of the power supply or connector will cause a high current to flow from the supply which could lead to damage both to the supply and to connected equipment and also a risk of fire and severe burns to persons. [. . . ] In addition, a Low Mains indicator is provided to alert the user to a mains undervoltage condition. 0 I Power Where multiple supplies are present, these should be switched on at the same time so that excessive load is not applied to any single supply. Power supply linking information is shown on the next page. Low Mains +48V +12V _ 18V +18V WARNING: HOT The internal operating temperature of the power supply could be sufficient to cause burns to persons. Do not open the cover or attempt to remove or bypass the safety covers protecting the fan and cooling channel. Operators Manual - Page 2 Using Multiple Power Supplies Using Multiple Power Supplies The number of power supplies shipped as standard with the Verona varies with the frame size as follows: Channels 24 - 32 40 - 56 64 Internal 1 2 2 External 0 0 1 Where multiple supplies are present, these should be switched on at the same time so that excessive load is not applied to any single supply. The external power supply can be used on 24-56 channel frame sizes to add redundancy or replace the internal supplies. [. . . ]
