Installation Manual Ilumen PID Box & Ilumen PID Control Box
are at the earth potential, if necessary you have to interconnect the mounting structures with
additional cables.

OX CONNECTION
To connect the Ilumen PID Control Box to the first Ilumen PID Box the cables with 4pole
connectors are used. You can use an extension cable (max 50m) in between made out of a four
wire cable of 4x1.5mm² and a!!!!!!!!!!!!!! female connector on one side and male connector on the
other side. The cable must be approved for outside use. Make sure the connectors are connected
correctly and screwed together tightly.

OX CONNECTIONS
When installing the Ilumen PID Solution between the PV array and inverter always switch off the
DC switch of the inverter.
TheIlumen PID Box side marked with “+” and “–“ will be connected to the inverter, the side
marked with “PV+” and “PV-“ will be connected to the solar arrays. If all connectors are installed
properly you can start connecting the PV arrays.
Always connect the PV arrays to the Ilumen PID Solution first; On the Ilumen PID BOX the “PV+”
cables should be connected to the positive side of all strings and the “PV-“ cables should be
connected to the negative side of all strings. Next connect the inverter. Connect the “+” cables of
the Ilumen PID Box to the positive input of the inverter (both cables MUST connect to the same
MPPT input). Connect the “-“ cables of the Ilumen PID Box to the negative input of the inverter
(both cables MUST connect to the same MPPT input).
All unused DC inputs and outputs have to be terminated with a corresponding sealing plug.
