9.1. Safety instructions for the DC connection

DANGER
DC cables connected to PV panels exposed to sunlight may be at a dangerously high voltage which could cause
serious injury and even death.
Before connecting DC cables to the inverter verify the absence of voltage.
Before starting the connection process, press the emergency stop button and keep it interlocked until all the
connections required for the unit to operate correctly have been made.
Make sure there is no voltage present on the unit before carrying out any connections. Once the inverter is
switched off, wait at least 10 minutes until internal capacitances are fully discharged.
After connecting the DC wiring, do not switch on the power until you have made all other connections and the
unit has been closed.
There is a risk of fire when using wiring gauges with a lower permissible current than the maximum possible
from the PV modules.
After working on the terminals the polycarbonate guard must be put back into place.
Failing to apply the correct tightening torques to the connection terminals causes a risk of overheating and fire.
Use the Personal Protective Equipment specified in section "Personal Protective Equipment".
CAUTION
In order to keep the nuts and bolts of the unit in good condition it is important to make sure there is no dirt or
shavings in the threads when screwing them in and apply a suitable lubricant.
The polarities indicated in the following figure must be followed. Ingeteam accepts no liability for any damages
caused by an incorrect connection.
Before connecting the wires, ensure that the DC fuses are not fitted in the bases. Install fuses once you have
connected the wiring and checked that the polarity is correct.
Ingeteam accepts no liability for the consequences of non-compliance with these instructions.
