The 5-pole terminal strip is used for connecting up a 24 V voltage
supply and for connecting a precharging contactor.
The connections for the contactor control are floating.
The position of the terminal strip can be seen from the connection
overviews.

AFE inverters of construction type J (compare above) require a supply
cable cross-section of 2.5 mm
F101 and F102 (fan fuses).
For AFE basic mains module, directly via the mounting surface and via
PE screw.
For AFE inverter via PE1 and PE2 and contact via the mounting
surface.
It is important to ensure that the basic mains module and the AFE
inverter are earthed at the same potential, use equipotential bonding if
necessary.
