Table 2-10. Mainframe Connector Terminations
Mainframe J1, J2, J3, J4, and J5 Connector Wire Size/Length
Connectors J1 and J2 contain high-speed digital signals that require controlled cable
impedances; connectors J3 and J4 contain noise-sensitive analog signals. Therefore, to
maintain signal integrity, cables must conform to construction requirements of AMETEK cable
assembly 53800054.

Input/output wiring must have a current carrying capacity compatible with the
current rating of the ReFlex Power™ system. The maximum current rating of a
wire is dependent on the materials used in its construction, and is primarily
limited by the insulation. The current must be limited so that the temperature rise
of the wire does not result in an operating temperature that exceeds the rating of
the wire.

Table 2-11 shows maximum current ratings, based on a cable of three
conductors, that will produce an approximate 30ºC temperature rise above
ambient. When wiring must operate in areas with an elevated ambient
temperature or bundled with other wiring, heavier gauges or higher
temperature-rated wiring should be used.
Although wire with higher temperature rated insulation will allow operation at
higher currents, the total voltage drop would also be increased for a given
wire gauge. For applications where voltage characteristics, such as
regulation, are important, it may be necessary to size the wire based on total
voltage drop instead of temperature rise.
