7.5.4 - Line reactors
A choke (as described in the table below) shall be installed on the line supply with installation instructions.
The cable length between the line reactor and drive shall be in accordance with the following table. The UL Tests for the certification
had been performed with the following line reactor characteristics:

7.6 - AC supply specification
Equipment suitable for use on a circuit capable of delivering not more than the values listed in the table of section 8.5.3.
7.7 - Motor overload protection and overspeed protection
The drive does not incorporate solid state overload protection for the motor load. The drive provides overspeed protection.
However, it does not provide the level of protection afforded by an independent high integrity over-speed protection device.
7.8 - PX1, PX2, PX3 and P2 customer interface
• The Powerdrive MD Smart inputs have a positive logic configuration. Using a drive with a control system which
has different control logic may cause unexpected starting of the motor.
• The Powerdrive MD Smart control circuit is isolated from the power circuits by single insulation. Its electronic 0V is
connected to the connection terminal on the outer protective conductor (earth terminal).
• The installer must ensure that the external control circuits are isolated against any human contact.
• If the serial link port (P2) or the control terminals (PX1, PX2) need to be connected to circuits complying with SELV safety
requirements, additional 4kV insulation barrier must be inserted to maintain the SELV classification (see EN 61140).
• USB port (P1): Use restricted to Cat. No. MDX-USB isolator option by Nidec Leroy-Somer (ordering code 4808979) for
ensuring a supplemental insulation for at least 600 V between the 24V circuits and user.
The PX3 output relay is limited for OVCII (Overvoltage Category 2) use (RL1 and RL2 must have the same polarity). The
voltage rating between two consecutive terminals must not exceed 150Vrms.
