- Page 2 GENERAL WARNING These symbols appear in this document whenever it is important to take special precautions during installation, operation, maintenance or servicing of the motors. It is essential that electric motors are installed by experienced, qualified and authorized personnel. In accordance with the main requirements of EC Directives, the safety of people, animals and property should be ensured when fitting the motors into machines.
- Page 3 FOREWORD Dear Customer, You have just acquired a Leroy-Somer motor. This motor benefits from the experience of one of the largest manufacturers in the world, using state-of-the-art technologies – automation, specially selected materials and rigorous quality con- trol. As a result, the regulatory authorities have awarded our motor factories ISO 9001, Edi- tion 2015 international certification from the DNV.

Page 21: Power Supply Cable Cross-Sections
ASSEMBLY AND COMMISSIONING RECOMMENDATIONS 3.5.4 - Power supply cable cross-sections With equivalent cable cross-sections, the higher the current, the greater the voltage drop in the cables (standard NFC 15.100 or end user’s national standard). The voltage drop must therefore be calculated for the motor's current rating indicated on the nameplate and acceptance will depend on the application and the type of cable. -
