ATENTION!
Provide at least 0.25 m (10 in) spacing between low voltage wiring
and drive/motor cables. For instance: PLC’s, temperature monitoring
devices, thermocouples, etc.
Table 3.3 presents minimum cable diameter and circuit breaker rating
for the CFW-10. Tightening torque shall be as indicated in table 3.4.
All power wiring (cooper) shall be rated for 70 ºC minimum.
Table 3.3 - Recommended wire cross-section and circuit-breakers - use (70 ºC) copper
