Lenze low-voltage machinery

General safety and and application notes for Lenze low-voltage machinery
(in conformity with the Low-Voltage Directive 73/23/EEC)
1. General
Low-voltage machines have dangerous, live and rotating parts as well as possibly hot surfaces. All operations serving
transport, connection, commissioning and maintenance are to be carried out by skilled, responsible technical
personnel (observe EN 50110-1 (VDE 0105-100); IEC 60364). Improper handling can cause severe injuries or
damages.
Synchronous machines induce voltages at open terminals during operation.
2. Application as directed
These low-voltage machines are intended for industrial and commercial installations. They comply with the
harmonized standards of the series EN 60034 (VDE O53O). Their use in hazardous areas is prohibited unless they
are expressly intended for such use (follow additional instructions).
The enclosures ≤ IP23 are by no means intended for outdoor use. Air-cooled designs are rated for ambient
temperatures between -15 °C and -10 ° C and +40 ° C and altitudes ≤ 1000 m a.m.s.l., from -20 °C to +40 °C without
brake or with spring-operated brake, with separate ventilation or self ventilation, from -15 °C to +40 °C with
permanent magnet brake and from -10 °C to +40 °C with separate fan. Check indications on the nameplate and if
they are different, observe them. The conditions on site must correspond to all nameplate data.
Low-voltage machines are components for the installation into machines as defined in the Machinery Directive
98/37/EC. Commissioning is prohibited until the conformity of the end product with this Directive has been
established (follow a.o. EN 60204-1).
The integrated brakes cannot be used as safety brakes. It cannot be ruled out that factors which cannot be influenced,
such as oil ingression because of a defective A-side shaft seal, cause a torque reduction.
3. Transport, storage
The forwarder must be informed directly after receipt of the goods about all damages or deficiencies; if necessary,
commissioning must be stopped. Tighten screwed-in ring bolts before transport. They are designed for the weight
of the low-voltage machine, do not apply extra loads. If necessary, use suitable and adequately dimensioned means
of transport (e.g. rope guides).
Remove the shipping brace before commissioning. Reuse it for further transports. For storage of low-voltage
machines ensure a dry, dust-free and low-vibration (v
rest). Measure the insulation resistance before commissioning. If the values are ≤ 1 k Ω per volt of rated voltage,
dry the winding.
4. Installation
Ensure an even surface, solid foot or flange mounting and exact alignment if a direct clutch is connected. Avoid
resonances with the rotational frequency and double mains frequency which may be caused by the assembly. Turn
rotor by hand, listen for unusual slipping noises. Check the direction of rotation when the clutch is not active (observe
section 5).
Use appropriate tools to mount or remove belt pulleys and clutches (heat generation!) and cover them with a touch
guard. Impermissible belt tensions must be avoided (technical list).
The machines are half-key balanced. The clutch must be half-key balanced, too. The visibly protruding part of the
key must be removed.
If required, provide pipe connections. Mounting positions with shaft end at top must be protected with a cover which
avoids the ingression of foreign particles into the fan. Free circulation of the cooling air must be ensured. The exhaust
air - also the exhaust air of other machines next to the drive system - must not be immediately taken in again.
