Editing Argon user guide/J4 connector wiring

{{SetAUGTitle|J4 connector wiring}}{{ArgonManualNav}}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.}}

===Wiring multiple drives with power supply & braking resistor sharing===
Note this drawing does not include wiring to motor (J4), motor brake (J3), feedback device (J1), controller (J5) and AC power input circuity.
{{caution|Using HV DC bus sharing via VP and VN terminals or supplying external DC voltage to them, renders the [[safe torque off]] STO1 input unusable because STO1 is based on by cutting the AC supply. In order to preserve STO1 functionality with DC bus sharing, the STO1 signal must be fed simultaneously to all DC bus sharing drives. If an external DC supply is used (no AC input to L & N), then STO1 will not operate.<br/><br/>STO1 will also be inoperable if DC voltage is supplied to L & N inputs instead of AC. With DC supply, STO1 ibput must be always powered as the internal relay may damage if STO1 used with DC supply. }}

===Detailed single drive wiring schematics===
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]].
