Power Cable and Connection
An IEC power connector is supplied with the HY-03 which has a moulded plug attached – this is a legal requirement. If no
moulded plug has been supplied with your HY-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 HY-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)
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 HY-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.
