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.
Check that the maximum current of the Q1 current breaker.
Before starting the installation up, we recommend preheating the compressor's housing.
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 lock.
Retighten the power connections once a year.
Check the wear of the switchgear once a year.
Clean the outer surface of the panel with a soft cloth, water and detergent. Do not use abrasive detergents, petrol,
white spirits or solvents.
