9. Start-up
Before performing the first energization of the unit, it is necessary to check a series of aspects in order to minimize
the consequences of an error during installation or connection. It is convenient to carry out the sequence of checks
in the order described below.
CAUTION
This start-up sequence must also be carried out whenever the unit is de-energized for more than 48 hours in a
row or when any modification has been made to the installation that may affect the auxiliary power supply (for
example, replacement of the auxiliary transformer). .
9.1. Visual inspection
The first thing to do is a visual inspection of all the unit and the installation to check that everything is in
accordance with the regulations in force in the place of installation and as described in this manual. It is
imperative to check the following points:
• Check that the power cables of the auxiliary circuit (the part coming from the outside) are correctly
crimped with their corresponding ferrules and correctly inserted in the terminal block.
• Check that the DC power cables are correctly connected to the corresponding plates. Special attention
must be paid to the correct alignment and position (one on each side of the plate) of the terminals in the
case of using two cables per pole.
• Visually check that there is no condensed moisture. In case of condensation, carry out a manual drying
process followed by aerothermal drying.
• Check that the refrigerant in the expansion vessel is near the middle. If the level is below, fill with a
special cooling fluid for aluminum circuits, based on ethylene glycol, with a minimum concentration of 40%.

9.2. Checking the functional insulation of the DC power circuit
In order to ensure that the functional insulation in the unit has not been compromised during the installation
process, the following check should be performed using a multimeter at the resistance measurement position:
• Check the insulation between the DC + and - connection plates. The multimeter measurement must give
a resistance value greater than 100 kOhms. Given the existence of capacitors between the + and - strips,
some polymeters can give a wrong insulation measurement.
• Check the insulation between each plate and the ground. Again the value must be greater than
100 kOhms.
