Always install the signal cables in separate trays from the power cables. The signal cable installation
and power cable installation on the same tray should satisfy one of the three conditions:
1) Install a grounded metallic separator, as illustrated in figure 9.7.

2) Predict a tolerance between the power cables and signal cables, using a cable tray, as illustrated in
figures 9.8 and 9.9.
NOTE
If the power cables operate with a voltage greater than 220 V and a current greater than 10 A, and are NOT
shielded, the distance from the signal cables should be at least 60cm.
