8. Combiner box - PV array connection
This chapter explains the requirements and process for connecting the combiner box to the PV array.
Read carefully before starting the connection process.
8.1. Safety instructions for the combiner box - PV array connection
Consult section "Important Safety Instructions" and the following instructions before working on the
unit.
Make sure there is no voltage present on the unit before starting the connection. Do not switch on the
power to the unit until you have successfully made the rest of the connections and the unit is closed.
Ingeteam accepts no liability for any damages caused by incorrect connection.
Use the personal protective equipment specified in the section "Personal Protective Equipment (PPE)".
8.2. Wiring requirements for the combiner box - PV array connection
Use copper cables.
Below we indicate the admitted section limits in the connections. The minimum sections indicated may not be
enough relative to the type of installation, so the installer must size the wiring relative to its needs.

8.3. Combiner box - PV array connection process
1.
Check that the combiner box DC switch is in OFF.
2.
With the combiner box open, remove the caps from the dedicated wiring accesses (one or two, depending
on the installation requirements).
3.
Install the couplings, not forgetting the insulating seals, and insert the plastic tubes that route the cable
though said couplings. Make sure the couplings are closed, following the manufacturer's instructions.
