Page 14: Safety Instructions
(in accordance with Low−Voltage Directive 2006/95/EC) For your personal safety Depending on their degree of protection, some parts of the Lenze controllers (frequency inverters, servo inverters, DC speed controllers) and their accessory components can be live, moving and rotating during operation. Surfaces can be hot. - Page 15 Safety instructions General safety and application notes for Lenze controllers Application as directed Controllers are components which are designed for installation in electrical systems or machines. They are not to be used as domestic appliances, but only for industrial purposes according to EN 61000−3−2.
- Page 16 Reduce housing openings and cutouts to a minimum. Lenze controllers can cause a direct current in the protective conductor. If a residual current device (RCD) is used as a protective means in case of direct or indirect contact, only a residual current device (RCD) of type B may be used on the current supply side of the controller.
- Page 17 Safety instructions General safety and application notes for Lenze controllers Maintenance and servicing The controllers do not require any maintenance if the prescribed operating conditions are observed. If the ambient air is polluted, the cooling surfaces of the controller may become dirty or the air vents may be obstructed.
