95 mm . Three are inserted in the front and three in the back. So up to four cables can be connected to each strip.

The maximum cable size is 240 mm
To avoid arcing, once the wires are connecting to the strips, check the safety clearances between live parts on each
strip or any other metal point on the unit. We recommend a clearance of 20 mm.
To access these terminals the protective polycarbonate sheet must be removed.
After working on the terminals the polycarbonate guard must be put back into place.

5.5. equipment configuration

Once the unit has been mounted in its final position and has been solidly secured, ensure that the inverter is properly
set up.
The units always come with factory settings, but when any of the electronics blocks of the units are replaced or repo-
sitioned, the block in question must be configured.
care must be taken to ensure the equipment is not live when accessing its interior.

5.5.1. cAn number setting of an electronics block

note that in case of changing any electronics block, these blocked come with default factory settings.
Once the unit is properly wired and before connecting it to the network and the PV array:
1. Press the emergency stop button.
2. Disconnect optical fibre cable from the electronics block to be replaced.
3. Open the Q4 thermomagnetic circuit breaker on the power module where the electronics block is being
changed.
4. connect Dc supply. Alarm 1143 will be activated.
5. In the display (see chapter 9 for details), find the "SeTTIngS" menu. Select "change numcAn". Press OK.
When prompted by the display, enter the installer code (3725) and press OK. Input the electronics block node. If
it was a replaced electronics block, proceed to the next step; if the set-up was for the electronics blocks of a unit
dependent on another unit, repeat the process for each electronics block.
6. Reset the alarms. To do so, close the Q4 thermomagnetic circuit breaker and connect the optical fibre
cables. Alarm 1000 will remain.
7. Once all units are properly configured and connected by fibre optic communication cable, connect the unit
after making the checks stipulated in chapter 6, commissioning.

5.5.2. configuring the Modbus node of an electronics block

Once the unit is properly wired, with cAn assigned and connected at least to the PV array:
1. check that the communication elements are in proper working order.
2. In the "SeTTIngS" menu. Select "change inverter number" and introduce the right one.
3. check that the communication also works with the new node number.
