Power Cable and Connection
An IEC power connector is supplied with the DHY-03 which has a moulded plug attached
– this is a legal requirement. If no moulded plug has been supplied with your DHY-03, please
contact your supplier, because an IEC connector is always supplied from the Sonifex factory.
If for any reason, you need to use the DHY-03 with a different power cable, you should use
the following wiring guidelines
Wire Colour
Connection
Green, or green and yellow
Earth (E)
Blue, or Black
Neutral (N)
Brown, or Red
Live (L)
Table B : Power Connections.
Connect the equipment in accordance with the connection details and before applying
power to the unit, check that the machine has the correct operating voltage for your mains
power supply.
Important Note : The terminal marked on the rear panel must be earthed.
Opening the DHY-03
If you need to get inside the unit to make configuration adjustments, simply remove the 4
screws in the corners of the rear panel. The rear panel and main PCB will slide backwards out
of the metal chassis.
Warning : The power must be switched off at the supply or the power lead must be
disconnected before attempting to open the unit. Removal of the cover can expose
dangerous voltages.
Warning : The telephone line plug should be disconnected from the telecommunications
network exchange line before removing the equipment covers.
Power For DHY-03EC
The DHY-03EC requires an extended DC supply of 5V or 15V (jumper selectable). This supply
should be isolated.
