Quick Start
3.1 Power Connections
The Ark 504, Ark 516 and Ark 516 Expander are supplied with a high quality power supply.
The power supply of the Ark 504 has enough power for one additional Ark 508 expander.
The Ark 508 Expander needs it’s own power supply when used with the Ark 516.
Make sure to use an earthed cable when connecting the AC power source to the 3-pin euro socket at the
back of the power supply.
The supply uses the latest ‘switch mode’ power techniques which negate the need for heavy and
inefficient power transformers. They are also extremely efficient which means that despite their high
current load capacity, they do not run hot. As a consequence cooling fans are not required and therefore
the power supply is completely silent in operation. As they still generate a small amount of heat it is
however always good practice to make sure that they operate in a well ventilated area, preferably with at
least 1U rack space between the supply and other equipment.
Another advantage of switch mode power supplies is that they will operate on a wide
AC input voltage range (100v to 260v AC). Consequently they can be operated virtually anywhere in the
world without the need for adjustment.
The supplies are provided with short-circuit and over-voltage protection.
Low voltage DC is supplied to the console via a circular locking connector.
- Push the connector firmly into the mating socket on the rear of the console.
- Use the locking ring to make sure that the cable cannot be accidentally pulled from the console.
- Make sure you make all connections before switching on the power supply.
The DC power connections are as follows:
Pin 1
Ground
Pin 2
+16V
Pin 3
-16V
Pin 4
+8V
Pin 5
+48V
The power supply is fitted with four red LED's which indicate that the +16, -16, +8V and +48 voltages
are functioning. If for any reason any of the LED's fail to illuminate, do not operate the console. Turn
the power supply off immediately and check that the appropriate front panel fuse(s) are not blown. If
any fuse has blown, replace with one of the same rating and try again. If the fuse has not blown or a
replacement fails subsequently, seek qualified help.
