2.6 Power Supply Connection
The NDS requires an external XP5 XS, XPS or 555PS power
supply connected to one (XP5 XS, XPS) or both (555PS) of
its power supply input sockets. Use only the Burndy cable or
cables intended for the specific power supply. Your retailer
or local distributor will be able to supply the appropriate
Burndy cable or cables.
IMPORTANT: XPS POWER SUPPLIES WITH SERIAL NUMBERS
BELOW 188015 ARE NOT COMPATIBLE WITH THE NDS AND
SHOULD NOT BE USED. CONTACT YOUR LOCAL NAIM
RETAILER OR DISTRIBUTOR FOR MORE INFORMATION.
If an XP5 XS or XPS power supply is used it should be
connected to NDS Power Supply Input 1. If a 555PS power
supply is used it should be connected to both NDS Power
Supply Inputs 1 and 2. The link plug must remain fitted to
Power Supply Input 2 unless a 555PS power supply is used.
Do not switch on the external power supply until all the
required NDS signal and network connections are made.
Note: It is possible to power the NDS using a multiple power
supply arrangement comprising two 555PS units, or a 555PS
and one other compatible power supply. Contact your
local Naim retailer or distributor for more information.
