Connections

Mains

The Merlin has a universal PSU suitable for direct connection to any mains voltage anywhere in the world. It is supplied fitted
with a standard UK 13A mains plug. For other territories a suitable approved mains adaptor must be used to suit the local mains
connector. Alternatively the UK plug may be removed and a suitable mains connector wired in its place. Wiring connections are
as follows;-
Brown Live
Blue Neutral
Green / Yellow Earth
The Merlin MUST be disconnected from mains before the mains plug is replaced. Replacing the plug should only be undertaken
by a suitably qualified electrical engineer.
Ethernet
The Ethernet connection is a standard 100BASE-T protocol computer network. Standard readily available CAT5 patch cables fitted
with RJ45 connections should be used to connect between the Merlin Ethernet port and either directly to a PC or to an Ethernet
