DC connection

9.4.2. DC connection process

DANGER
Reverse connection of the DC would have fatal consequences on the unit and could cause serious damage to
persons close to the unit.
Respect the connections indicated in the figures bearing in mind the polarity.
CAUTION
In the DC connections the forces exerted by the cabling must not deform the plates. The maximum vertical
limits are indicated in the following figure.
Appropriate systems must be installed to ensure this requirement is met. Ingeteam accepts no liability for the
consequences of non-compliance with this warning.
To connect the DC wiring, carry out the following process:
1. Access the DC power supply by removing it and the dedicated panels.
2. If the unit has DC feed fuses, ensure that these are not fitted in their bases. If this is not the case,
remove them (see Section "9.5. Connection/disconnection of the DC fuses").
3. Strip the cable according to the size of terminal to be used.
4. Crimping the terminal on the cable.
5. Clean the contact surfaces on both the terminal and the connection bar with a clean cloth and ethanol.
6. Connect the terminal to the busbar via the bolts and washers supplied by Ingeteam upon delivery of the
unit, respecting the indicated tightening torque and polarities indicated in the following points of this
section, relative to the fuses installed (see figures below).
7. Check polarity of the strings connected to the inverter. If the polarity is incorrect, change it. Connecting a
string with the incorrect polarity and starting up the unit can cause irreversible damage to the unit.
8. If the unit has fuses, install them in their bases (see Section "9.5. Connection/disconnection of the DC
fuses").
9. Reinstall it or the panels.
