• It is compulsory to connect to the protection earth, making sure that this is done before powering up the input of the RE2 or
PLC2.
For the small equipment (line cord fitted with plug), the user should make sure that the mains outlet corresponds to the
type supplied, with the earth properly installed and connected to the site's protection earth.
For all other equipment (fitted with terminals) the installation technician should connect the earth wire to the correspond-
ing terminal.
• Manipulation inside the equipment involves the risk of electric shock and therefore it is restricted to authorised and
qualified personnel only. For maintenance or failure, contact your nearest After Sales Service (A.S.S.)
• The installation of the RE2 and PLC2 fitted with terminals should be carried out by technicians qualified in the low voltage
electrical installations.
• The regulation is done independently between the phases. In the case of unbalanced three phase mains supply or
unbalanced loads, the phase to phase output voltage might not be equal, however it will keep the regulation phase to
neutral.
• It is essential to connect the input Neutral of the RE2 three phase voltage stabilisers: this requisition is not needed for the
three phase PLC2 (voltage stabilisers with galvanic isolation transformer).
• The PLC2 (voltage stabilisers provided with galvanic isolation transformer) can be connected to the type of neutral
wished. For the type of isolated neutral, the wire bridge linking the output terminal to the earth terminal should be
removed.
