Editing Argon user guide/J4 connector wiring

J4 is a 10 pole terminal block connector for several functions: earthing, AC power input, motor output, regenerative resistor output and HV DC link sharing. See also the main article about [[Argon user guide/Wiring|Argon wiring]].

{{electricshock|Dangerous & non-isolated mains potential voltages are present in the connector J4! Keep away from this connector and its wiring when drive has been powered recently. Carefully read the page [[Power supply safe discharging]] before operating.}}

==J4 wiring guide==
Basic wiring scheme of Argon (servo drive). Use of shielded cables is optional but highly recommended for EMI compliance and optimal reliability. For recommended accessories (EMI filters etc, see [[Argon user guide/Mating connectors and accessories|Mating connectors and accessories]].
