14.2 Loads on terminals, cable lengths and cross-
sectional areas
• Max. perm. mains primary fuse (external)
• Unit fuse F1 (internal)
• The mains input current depends on the status of the unit
• Safety shutdown from operating position at mains voltage
• Restart on increase of mains voltage
• Nominal voltage
• Nominal current
• Power factor
• Nominal voltage
• Nominal current
• Power factor
Status inputs (with the exception of the safety loop) of the contact feedback network
(CFN) are used for system supervision and require a mains-related input voltage.
• Input safety loop
• Input currents and input voltages
