8.3.1 Rated Current and Cable Specifications
Table 8.2 Wire Size Examples
Note 1. Cable selection conditions: three cables per bundle at 40 °C ambient temperature with the rated current flow-
ing.
2. Use cable with 600 V min. withstand voltage for main circuits.
3. Consider allowable current reduction ratio if cables are bundled in PVC or metal ducts.
4. Use temperature-resistant cable under high ambient or panel temperatures where normal vinyl cables rapid-
ly deteriorate.
Table 8.3 Cable Types
Note 1. Use cable with 600 V min. withstand voltage for main circuits.
2. Consider allowable current reduction ratio if cables are bundled in PVC or
metal ducts.
3. Use temperature-resistant cable under high ambient or in-panel temperatures
where normal vinyl cables rapidly deteriorate.
The following table shows specifications of cables used for SERVOPACK connectors 1CN and
2CN.
