9.3. Auxiliary circuit energization
Before introducing external voltage in the auxiliary circuit, make sure that all the protection devices of the auxiliary
circuit are tripped. Once the external voltage has been introduced, measure at the FC1 terminals and check (using
a multimeter) that the voltages between the phases (400 V), and between phases and neutral (240 V) are correct.
Next, raise the FC1 protection and progressively raise the rest of the protections, observing any malfunction.
Once the central control of the charger has started, the HMI screen will show the charging sockets available on
the charger with an alarm symbol. Pressing on any of them you enter the alarm panel, where codes 12 and/or 13
should be displayed, indicating that there is no DC voltage in the charger.
9.4. Checking the direction of rotation of the pump
CAUTION
Failure to ensure the correct direction of rotation of the pump can cause overheating at the charging terminal
and, at one end, can cause a component to break.
If it is necessary to change the phases due to incorrect rotation of the pump, first make sure that the voltage in
the auxiliary terminal block has been eliminated by means of the switch external to the charging terminal.
Once the auxiliary power supply circuit is connected, it is necessary to check that the direction of rotation of the
cooling pump is correct. This can be done with a phaser or, failing that, by visual inspection. For the latter, the rear
of the pump can be accessed through the rear door. With the pump activated, check that the direction of rotation is
as indicated on the pump casing (a very thin flange can be slightly inserted through one of the fan holes to check
the rotation).
If the direction of rotation is the opposite to that indicated, two of the phases (R and S, for example) must be
exchanged in the auxiliary terminal block (see section
“7.3. AC auxiliary circuit connection process”

9.5. Energizing the DC power circuit
DANGER
In case of energizing the DC power circuit with a wiring error or a damaged component, it can generate a
deflagration that, if a door is open, could reach someone in the surroundings.
The energization of the DC power circuit can only be done with all the unit doors closed and interlocked by
means of their corresponding locks.
To energize the circuit, it is necessary to close the external disconnector corresponding to the unit to be energized.
In the event that the main rectifier is already energized and active (there is voltage in the DC distribution grid),
the unit will start an automatic pre-charging and connection sequence to the DC network. Once this process is
complete, the charging station display should not show an alarm.
