the capacitors or capacitor banks.
Incorrect installation and use may lead to the risk of electric shock or fire. Capacitor banks must be

used in normal conditions, in other words they must not be subjected to any other
Voltage/Current/Frequency/Harmonic distortion/Temperature values than those specified in the sales
catalogue and manual.
 Only use accessories recommended by the Legrand Group in the sales catalogue and manuals.
 As we are keen to ensure the highest levels of performance of our products, they may be subject to
modification. Please check the accuracy of the product specifications during installation and

physical injury or material damage.
 Ensure that the automatic capacitor banks are correctly earthed.
 Switch off all the capacitor bank power supplies before working on it.
 Before working on live parts, wait at least 5 minutes for the capacitors to discharge, then short-circuit
the terminals and earth the capacitor.
 During operations involving access inside the capacitor bank, beware the risk of burns when touching
the products or metal parts (during operation or just after the capacitor bank has been switched off).
 Before restoring power to the capacitor bank, check that all the physical protection devices have
been replaced (for example: shield, cover, door).
 Any failure to follow procedures and warnings to the letter can lead to premature failure,
explosion, or an outbreak of fire in the equipment.
