Installing a power input connector
To install a Neutrik PowerCon NAC3FCA input connector on a power
cable, see illustrations above and right:
1. Slide the bushing over the cable.
2. Slide the white chuck over cables with a diameter (D
a
) of 5 - 10 mm
(0.2 - 0.4 in.), or the black chuck over cables with a diameter of 10 -
15 mm (0.4 - 0.6 in.).
3. Prepare the end of the cable by stripping 20 mm (0.8 in.) of the
cable’s outer jacket.
4. Strip 8 mm (1/3 in.) of insulation from the end of each wire.
5. Use a small flathead screwdriver to fasten the wires into the
connector terminals in the insert as follows:
• live wire into the terminal marked L
• neutral wire into the terminal marked N
• ground (earth) wire into the terminal marked .
6. Line up the raised key in the insert with the keyway in the housing,
then push the insert and chuck into the housing.
7. Fasten the bushing to the housing using a wrench, applying a
torque of 2.5 Nm (1.8 lb.-ft).

Installing a cord cap (mains plug)
If you install a cord cap (mains plug) on the power cable to allow connection to power outlets, install a
grounding-type (earthed) plug, following the plug manufacturer’s instructions. Table 1 shows some possible
mains power pin and wire color identification schemes; if pins are not clearly identified, or if you have any
doubts about proper installation, consult a qualified electrician.
Applying power
To apply power, first check that the tilt lock is released and then set the power switch on the base to the “I”
position.
