3.4 Cables and fuses
The AC supply inputs in the FXM5 controller are fitted with fuses for protection
against overload and short circuits in the FXM5 controller and field-winding of the
motor. These fuses will not protect the supply cables to the FXM5 controller. The
table shows recommended cable sizes and fuse ratings for a number of current
levels. Failure to observe this recommendation will cause a risk of fire.
Wiring must be in accordance with local regulations and codes of practice. The
table shows typical cable sizes for power input and output wiring. In the event of
a conflict, local regulations prevail.
For the following power connections...
• AC supply to the isolator and fuses
• Isolator and fuses to the Drive
• Drive to the motor
• External braking resistor to the Drive (when required)
...use the following:
• 3-core and 4-core pvc-insulated cable with copper conductors having a temperature
rating not less than 60/75°C and laid in accordance with defined conditions. Refer to
EMC recommendations later in this chapter for shielding requirements.
• The wiring must conform to local regulations and codes of practice. Refer to the
following table for the size of the AC supply and field-winding cables. In the event of
conflicting data, local regulations prevail.
