Power cables and power plug
The product requires a power input cable with a Neutrik powerCON TRUE1 NAC3FX-W (255.700)
or CEE 16A (255.701) cable connector for AC mains power input. The cable must be rated 20 A
minimum, have three (255.700) or five (255.701) conductors 1.5 mm2 (AWG16) minimum
conductor size and an outer cable diameter of 6-16 mm (0.24-0.47 inch). Cables heat-resistant to
90°C (194°F) minimum. In the EU the cables must be <HAR> approved or equivalent and in the
USA minimum hard usage type (SJT or equivalent).
If you install a power plug on the power cable, install a grounding-type (earthed) plug that is
rated 20 A for USA and 16A for Europe. Follow the plug manufacturer’s instructions. Table 1
shows standard wire color-coding schemes and some possible pin identification schemes; if pins
are not clearly identified, or if you have any doubts about proper installation, consult a qualified
electrician.
