5.5.1 Connection schematic
The recommended connection schematic is shown on the following page; these devices are designed to
operate with TT or TN distribution networks.
For use in accordance with UL certification, only TN distribution is permitted.
The power supply unit can operate on both single-phase or three-phase networks. In case of single-phase, it
is necessary to reduce the output current and set the device to single-phase mode by means of the jumper (see
specific paragraph). If the device is set in the wrong way, the overload protection and the missing phase de-
tection will not function correctly.
WARNING
AVERTISSEMENT
The device and the power conductors must be protected against overcurrents and short-circuits by a suitable
protection device. Since the input current is strongly distorted by the rectifier, its value may be considerably
higher than the output current; therefore the protection devices must be selected carefully.
A wrong setting of the device may cause overload, with consequent danger of fire and pos-
sible damage to people and things.
Un réglage incorrect de l'appareil peut causer des dommages dus à une surcharge, à un
risque d'incendie et à des dommages corporels ou matériels.
