Table 4-2 Typical cable sizes
Input/Output
1. Assumes the use of XLPE or EPR insulated cables in mounting method B2 as per
Table B52.5.
2. Assumes the use of 75 °C copper cable as per table 310.16 of the National
Electrical code.
4.5.1 Armature connections A1 A2
Connection to A1, A2 is only required in stand alone mode for voltage monitoring of the
armature voltage during field weakening. Armature branch fuses should be located
close to the armature supply and sized to protect the cable from the fuses to the
FXMP25. Cables 0.5 mm

NOTE
protection is required for cable and internal control electronics protection.
4.5.3 Internal semiconductor fuses
The internal semiconductor fuses provide protection to the FXMP25 SCR / thyristor
bridge only. The fuses can rupture if there is a fault in the field circuit. The user should
check the internal semiconductor fuses if the FXMP25 is tripping field loss (FdL) while
enabled.
Electric shock risk
If the FXMP25 controller has been energized, the supply must be isolated for at least
five minutes. This allows the internal capacitors to discharge fully before work may

commence.
