SERVOPACK Main Circuit Wires
The wires used in the SERVOPACK main circuit are described below.
Single-phase, 100 V
Three-phase, 200 V
• Wire sizes are selected for three cables per bundle at 40
C sur-
rounding air temperature with the rated current.
• 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.
