ArmorStart Device Wiring
Wiring in an industrial control application can be divided into three groups; power, control, and signal.
Follow these recommendations for physical separation between these to reduce the coupling effect:
• Minimum spacing between different wire groups in the same tray should be 16 cm (6 in.).
• Run wire outside an enclosure conduit or have shielding or armor with equivalent attenuation.
• Run different wire groups in separate conduits.
• Minimum spacing between conduits containing different groups should be 8 cm (3 in.).
The table provides power, control, ground wire capacity, and tightening torque requirements. The power,
control, ground, and safety monitor terminals accept a maximum of two-wire per terminal.
