1.3.4 AC cables
The Genesys series is cooled by internal fans. At the installation, care must be taken to
allow free air flow into the power supply via the front panel and out of the power supply via
the rear panel. The Genesys power supplies have a compact and lightweight package
which allows easy installation and space saving in the application equipment.
Accessories are delivered with the power supply or separately upon ordering. The list below
shows the possible accessories and ordering numbers.

1.3 ACCESSORIES
erial link cable, for linking power supplies by RS485 communication is provided with the
power supply.
Cable description: 0.5m length, shielded, RJ-45 type plugs, 8 contacts (P/N: GEN/RJ45).
* DB25 plug kit (AMP, 749809-9).
* Output terminal shield
AC cables are not provided with the power supply. If an AC cable is required, it should be
ordered according to following:
Part no. Market Description
NC301 USA 13A125V, unshielded, 2m typical length, with IEC320 connector on
one end and NEMA-5-15P connector on the other end.
NC302 Europe 10A 250V, unshielded, 2m typical length, with IEC320 connector
on one end and INT’L 7 standard VII, dual earthing.
NC303 General 10A 250V, unshielded, 2m typical length, with IEC320 connector
on one end and unterminated stripped wires on the other end.
Use the cable only with plug approved by the national safety
standards of the country of usage.
NC305 Japan 13A 125V, unshielded, 2m typical length, with IEC320 connector
on one end and Japan type plug on the other end.
NC306 UK 10A 250V unshielded, 2m typical length, with IEC320 connector
on one end and UK type plug on the other end.
For 1500W Genesys power supplies the recommended AC cable (customer supplied) is:
25A 250V, 3x12AWG, outer diameter: 9-11mm, rated 60 C min.,
3m max. length. Add a non-locking plug approved by the national
safety standards of the country of usage.
