HE USE OF A
Please consider the following advice. Certain inverters stay connected to the grid while other
inverters completely shut of the AC-side. Here are the 2 different situations.
•
If the inverter, during the night, is disconnected from grid (normal condition) there is no
problems because the leakage current with respect to ground ,provided by PID box,
flows only into the solarpanels.
•
If the inverter, during the night, remains connected to grid (this may happen if certain
functions are set into the inverter) the leakage current with respect to ground ,provided
by PID box, flows into both panels and the neutral wire (referred to ground in a TT
system). This leakage current flow inside the PV plant RCD.
If the AC output of more inverters with PID boxes are connected to a single RCD the sum of the
currents provided by PID boxes may cause the RCD tripping (i.e. 6 inverters with 6 PID boxes
can generate 6x5mA = 30 mA).
Always place the PIDbox Light behind a 300mA RCD to make sure the RCD is not
tripped because of the leakage current of the PIDbox Light. Also limit the number
of PIDboxes to 60 devices connected to 1 RCD of 300mA.

Do a final check whether everything is properly mounted and connected (see chapter 5 and 6 for
details):
✓ The PV frames are all connected to the same earth as the earth pin of the Ilumen PIDbox
Light
✓ The PV and inverter DC cables are correctly connected
✓ Unused DC inputs are terminated with a corresponding sealing plug
✓ The DC side of DC power supply is correctly connected
If all these points are installed correctly you can start up the Ilumen PIDbox Light.

TARTING UP THE
The Ilumen PIDbox Light can only work in an automatic mode. To start up the Ilumen PIDbox
Light, plug in the DC power supply into a standard AC outlet (This outlet must be on at all times).
Next see if the LED light on the Ilumen PIDbox Light starts burning. After checking the system it
will be switched on automatically.
When the Ilumen PIDbox Light is hooked up correctly to the inverter you will see the following
status LED readouts.
