(2) Main Circuit Wires
This section describes the main circuit wires for SERVOPACKs.
Single-phase, 100 V
Three-phase, 200 V
Three-phase, 400 V
• The specified wire sizes are for use when the three lead cables are bundled and when
the rated electric current is applied with a surrounding air temperature of 40 °C.
• Use a wire with a minimum withstand voltage of 600 V for the main circuit.
• If cables are bundled in PVC or metal ducts, take into account the reduction of the
allowable current.
• Use a heat-resistant wire under high surrounding air or panel temperatures, where
polyvinyl chloride insulated wires will rapidly deteriorate.
