3.3 General safety and application notes for Lenze motors
(in comformity with the Low-Voltage Directive 73/23/EEC)
Low-voltagemachineshavedangerous, live and rotating parts as well aspossibly
hot surfaces. All operations serving transport, connection, commissioning and
maintenance are to be carried out by skilled, responsible technical personnel
(observe EN 50110-1 (VDE0105-100); IEC 60364). Improper handling can cause
severe injuries or damages.
Synchronous machines induce voltages at open terminals during operation.
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).
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 °Cto+40°C and altitudes ≤ 1000 m a.m.s.l.,
from -20 °Cto+40°C without brake or with spring-operated brake, with
non-ventilated or with integral fan, from -15 °Cto+40°C with permanent magnet
brake and from -10 °Cto+40°C with separate fan. Check indications on the
nameplate and if other, 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 guaranteed
that factors, which cannot be influenced, such as oil ingression because of a
defective A-side shaft seal, cause a torque reduction.
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).

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 ≤ 1kΩ per volt of
rated voltage, dry the winding.
