These symbols are internationally accepted symbols that warn of potential hazards with
electrical products.
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
sufficient magnitude to constitute a risk of electric shock to persons.
The exclamation point within an equilateral triangle is intended to alert
the user to the presence of important operating and maintenance
(servicing) instructions in the literature accompanying the appliance.
1. Read these instructions.
2. Keep these instructions.
3. Heed all warnings.
4. Follow all instructions.
5. Do not use this apparatus near water.
6. Clean only with a dry cloth.
7. Do not block any of the ventilation openings. Install in accordance with the manufacturers
instructions.
8. Do not install near any heat sources such as radiators, heat registers, stoves, or other apparatus
(including amplifiers) that produce heat.
9. 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. If the provided plug does not
fit into your outlet, consult an electrician for replacement of the obsolete outlet.
10. Protect the power cord from being walked on or pinched particularly at plugs, convenience
receptacles, and the point where they exit from the apparatus.
11. Only use attachments / accessories specified by the manufacturer.
12.Use only with the cart, stand, tripod, bracket, or table specified by the manufacturer,
or sold with the apparatus. When a cart is used, use caution when moving the
cart/apparatus combination to avoid injury from tip-over.
13. Unplug this apparatus during lightning storms or when unused for long periods of time.
14. Refer all servicing to qualified personnel. Servicing is required when the apparatus is damaged in
any way, such as power-supply cord or plug is damaged, liquid has been spilled or objects have
fallen into the apparatus, the apparatus has been exposed to rain or moisture, does not operate
normally, or has been dropped.

Installation and ServiceInstallation and Service
The V190 series power supply unit is a two unit nineteen inch (2U 19”) rack mounted power supply for use with the Midas
Verona series of consoles only.
Installation
Before installing the power supply, please ensure that the correct mains supply voltage is selected on the rear of the supply.
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.

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.

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.
The V190 power supply should be connected to the mains with the supplied IEC mains leads.
220VAC
The V190 is a Linear power supply capable of operation where the nominal mains voltage is 100, 120,
220 or 240 VAC (50-60Hz). The correct mains supply voltage must be selected before applying mains
power to the unit.
To change the mains operation voltage, disconnect from the mains. Open the compartment above the
mains inlet connector with a flat bladed screw driver. Once open, you will see a drum with an operating
voltages printed on each face. Remove the drum, then turn the drum to the required voltage and return
o the holder. Press firmly and then close the compartment. Make sure that the correct voltage now
it t
appears in the window of the compartment.
The Midas V190 power supply MUST be earthed. The power supply should NEVER be used with the earth connection
NOTE:
removed. The mains inlet socket earth connection is a safety connection and should be connected to the mains earth
through the earth conductor in the provided mains lead.
WARNING:
To prevent the risk of fire, fuses should always be replaced with fuses of the same rating and type.
Operation
After connecting the V190 power supply to the console, switch on the power supply using the rocker switches on the front
panel. Power will be applied to the console.
The user may monitor the activity of each of the voltage rails using the LEDs on the front panel. Each LED will light to show
the rail is active. In addition, a Low Mains indicator is provided to alert the user to a mains undervoltage condition.

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.

Using Multiple Power SuppliesUsing 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:
ChannelsInternalExternal
24 - 3210
40 - 5620
6421
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.
Two external supplies would be required to replace the internal supplies of the 56 channel console and retain redundancy.
The external supply has a “daisy chain” facility (as shown below) allowing for a number of power supplies to be used
together adding redundancy to the system in the event of a power supply failing.
Under NO circumstances should the Venice series power supply be used with the Verona.
Only the MidasV190 Linear External Power Supply is approved for use with Verona consoles.
