Make sure your
power is not on, unplug the lead from the wall socket.
Cooling Fan to the DC Converter
The first step
is to remove the Molex plugs, cut the fans DC wires as close
to the Molex plugs as possible. The plugs can be discarded
Strip back the
insulation approx 6mm and give the wires a twist to bind the
With a Philips
screw driver loosen of terminals 2 and 3 on the DC Converter.
Insert the DC+
wire from the Cooling fan into Terminal 3 (12V DC+ Out) on
the DC Converter and tighten screw.
Now plug the
Terminal block into pins 16 and
Insert DC- wire
from the Cooling fan into Terminal 2 (DC- Common) on the DC
The Fan is now
wired to the DC Converter
DC Converter to the Power Supply
Using the same
method for measuring wires all throughout these
instructions, run a black (DC-) wire from Terminal 6
(DC- Out) on the Power Supply to Terminal 2 (Common DC-) on
the DC Converter. Allow for an additional 10mm at the
Power Supply and 6mm at the DC Converter. Strip back the
insulation 10mm at one end and 6mm at the other.
Now run a Red
(DC+) wire from Terminal 3 (DC+ Out) on the Power Supply to
Terminal 1 (DC+ In) on the DC Converter. Allow
for an additional 10mm at the Power Supply and 6mm at the DC
Converter. Strip back the insulation 10mm at one end and
6mm at the other.
Attach a Fork
terminal to the 10mm stripped end of each wire.
With a Philips
head screwdriver loosen off terminal 3 on the Power Supply
and terminal 1 on the DC Converter.
Attach the fork connector on the Red (DC+) wire to Terminal
3 on the Power Supply and tighten screw. Insert the
stripped end of the same wire into Terminal 1 on the DC
Converter and tighten screw
Now loosen off
terminal 6 on the Power Supply. Attach the fork connector on
the Black (DC-) wire to Terminal 6 on
the Power Supply and tighten screw. Insert the stripped end
of the same wire into Terminal 2 on the DC Converter
(The DC- wire from the Cooling fan should already be
attached to this terminal, I know it seems strange but yes
the 24V and 12V system share the same "Negative" terminal),
The Cooling Fan
and DC Converter are now wired.
It's now time
to connect the power supply to power and test the Cooling
Fan. Make sure the Power switch on the
Power chassis is in the "Off" position. Insert the power
lead into the chassis. Turn off your wall socket and plug
power lead in. Turn on the wall socket and turn on
your power switch. The Green LED on Power supply should be
and the Cooling Fan should be rotating (Cooling fan has blue
LED's which should also be illuminated).
unit for a minute or so to make sure nothing is wrong, Turn
it off at the switch then the power point and
from the wall. Always unplug your power supply when not
in use. After turning off your power supply, please
60 seconds before turning it back on.
