2.2 General safety and application notes for Lenze motors
(to: Low-Voltage Directive 73/23/EEC)
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 qualified, skilled personnel (observe EN 50110-1 (VDE 0105-100);
IEC 60364). Improper handling may cause severe injury to persons or damage to material
assets.
Synchronous machines induce voltages at open terminals during operation.
Application as directed
These low-voltage machines are intended for industrial and commercial installations.
They comply with the harmonized standards of the EN 60034 (VDE O53O) series. Their use
in hazardous areas is prohibited unless they are expressly intended for such use (follow
additional instructions).
Degrees of protection ≤ IP23 are only intended for outdoor use when applying special
protective measures. Air-cooled designs are rated for ambient temperatures from -15 °C
and -10 °C to +40 °C and altitudes ≤ 1000 m a.m.s.l., from -20 °C to +40 °C without brake
or with spring-operated brake, non-ventilated or with integral fan, 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 machinesare componentsfor the installation intomachinesasdefinedinthe
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 guaranteed that
factors which cannot be influenced, such as oil ingression because of a defective A-side
shaft seal, do not cause a torque reduction.
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 braces before commissioning. Reuse them for further transports. For
storage of low-voltage machines ensure a dry, dust-free and low-vibration (v
rms
≤ 0.2
mm/s) environment (damage while being stored). Measure the insulation resistance
before commissioning. If the values are ≤ 1 kΩ per volt of rated voltage, dry the winding.
