VN-Matrix 300 • Installation and Basic Setup Procedures 14
Fitting a Mains Plug
If you are fitting a plug to the unterminated power cord (or replacing an existing plug), you
must fit a plug that:
z Is rated for use with mains voltage
z Is equipped with a grounding pin/connection
z Complies with any applicable National or Local electrical regulations.
z Is tted with a correctly rated fuse (applicable to UK-style plugs only, see page 13)
WARNING: Never attempt to fit or use a plug without a ground or earth pin/
connection.
Wiring Details
The wires of both mains power cords (supplied with each VN-Matrix 300) are color-coded
as shown in the table below; be sure to connect your plug in accordance with the following
guidelines:
Connect the wire colored... to the plug terminal identified with...
Brown L or Live or Line
(or colored red or brown)
Blue N or Neutral
(or colored blue or black)
Green and Yellow E or E or Earth or Ground
(or colored green or green & yellow)
WARNING: If you are unsure of the connections, or if the markings in your plug do not
match those given above, CONSULT A QUALIFIED ELECTRICIAN.
NOTE: The PSU is double-insulated and does not require an earth/ground connection.
However, the earth cable of the mains lead must be connected in the plug.
External Supply Protection
CAUTION: The mains power cord supplied with this product is rated at 10A maximum
and must be protected from overload by an external fuse or circuit breaker.
Fused Plugs (UK-style)
If the power cord is tted with a UK-style BS1363 3-pin plug (that is, with provision for an
internal fuse), then it must be tted with a BS1362 ASTA approved 1 inch cartridge fuse.
This fuse must be rated at a maximum of 10A/250V. Since the current draw of the PSU is
less than 1A, a fuse of a lower rating not less that 3A/250V may be used.
WARNING: Never attempt to fit a fuse or circuit breaker of a higher maximum rating
than shown above.
