Installation manual
communication via serial RS-485, install the new board. To do this, the "AAP0022 com RS-485" board of the first
module must be replaced with the "AAX0004 com ethernet + RS-485" board. Observe the precautions stipulated in
section 4 for Handling tasks.
Once mounted on the board, the communication RS-485 cables must be wired as they were on the other board, and
the rod must be connected as described above.
See "AAX2002IKI01Installation guide for communications Devices".

5.4.10. connection for fibre optic communication

At the request of the installer, inverters may optionally incorporate hardware for communicating via fibre optic cable.
This hardware comprises one to four "AAP0009 com Fibra" boards (one per module except module 1) that are
supplied mounted on the control board in each power block, a +5/10 W power supply and wiring between the blocks
(AQL0019 units).
The boards are supplied fully assembled, connected by fibre optic cables and fed from the power source located in
the first power module. The cable connecting the unit to the outside will have to be connected to the fibre optic cable
connecter closest to the power feed for module 1.
See "AAX2002IKI01Installation guide for communications Devices".

5.4.11. ground connections

The metal parts of the inverter (equipment ground) are electrically connected to the grounding bar on the front of each
cubicle containing the the electronics of the equipment.
To ensure the safety of personnel, this terminal must be connected to the installation's ground.

5.4.12. connecting the auxiliary supply

The fans, contactors, auxiliary power electronics and lighting of the cabinet if any, require backup power to operate.
This power must be provided at the two-terminal terminal strip installed for this purpose and should be 230 V 50 Hz.
The power it should provide depends primarily on the number of fans it has to feed:
• units with 4 blocks: 2500 VA
• units with 3 blocks: 2100 VA
• units with 2 blocks: 1300 VA
The auxiliary input is in the cubicle of the first power module, as shown in the following figure.
