Recommendations
ATTENTION!!
Disconnect the voltage before carrying out any operations inside the electrical panel.
All wiring should be according to current standards and should be carried out by authorised staff.
Only carry out the wiring foreseen in the wiring diagrams.

Panel installation:
Do not knock or move the panel abruptly.
Carry out the wiring according to the installation manual.
The probes and their cables should NEVER be installed in a conduit together with power, control or feeder cables.
The earth terminals that the panels contain are installed to guarantee the continuity of earthing, however, earthing
is not carried out by the terminal and should be carried out outside the panel.
The neutral ratings are TT or TNS. The IT rating should not be used.
Circuit breakers (protective switches) are of the phase/s + neutral, curve C type, guaranteeing switching and
protection against overcurrent.
Close the panel when your are not working on it.
Main switch connection and residual current protection outside the electrical panel according to low voltage
electrotechnical regulations.
Checks before starting the panel up:
The power supply voltages and frequencies will be those indicated in the table and diagram corresponding to each
panel model.
Check that there are no loose parts or foreign bodies on connections or switchgear.
Check that there is no dust or damp inside the panel.
Check the correct fastening of the switchgear and components.
Check the correct tightening of the screws and power connections.
Check the correct connection of the power conductors.
Check the correct insulation of the outer lines and that they do not mechanically force the inner connections of the
panel.
Checks during the panel start-up:
Check that no electric arcs occur.
Check that the relays or contactors do not produce ratios.
Check that there is no overheating in cables, controllers and the rest of the switchgear.
Checks after the first 24 hours of operation:
Check that no overheating occurs.
Retighten screws and power connections.
Periodical preventive maintenance:
The panel should remain closed using its anchors.
Retighten the power connections once a year.
Check the wear of the switchgear once a year.
