ATTENTION!
Sensitive equipment, such as PLCs, temperature controllers and thermocouple cables must be
placed at least 25 cm away from the cables between the regulator and the machine.

NOTE!
The values of Table 5.1 are only valid in the following conditions:
■ copper cables with PVC 70°C (158 F) insulation;
■ maximum ambient temperature of 50°C (122 F);
■
installation in vertical or horizontal perforated channels;
■ arrangement of the cables in a single layer.
For installation in other conditions, refer to NBR 5410.
NOTE!
The output wiring of the regulator (F+ / F-) must be installed separately from the input power wiring
(P-A/P-B/P-C), as well as from the control and signal wiring.
5.3.2 Protection Fuses
In order to protect the product against short circuit, ultra fast fuses must be used at the regulator input,
dimensioned according to the current and to the maximum of the power I
