General safety and application instructions for Lenze motors
(According to: Low-Voltage Directive 2006/95/EC)
General
Low-voltage machines have hazardous live and rotating parts and possibly also hot
surfaces.
Synchronous machines induce voltages at open terminals during operation.
All operations concerning transport, connections, commissioning and maintenance must
be carried out by qualified, skilled personnel (EN 50110-1 (VDE 0105-100) and IEC 60364
must be observed). Inappropriate use creates the risk of severe injury to persons and
damage to material assets.
Low-voltage machines may only be operated under the conditions that are indicated in the
section ”Application as directed”.
The conditions at the place of installation must comply with the data given on the
nameplate and in the documentation.
Application as directed
Low-voltage machines are intended for commercial installations. They comply with the
harmonised standards of the series EN 60034 (VDE 0530). Their use in potentially
explosive atmospheres is prohibited unless they are expressly intended for such use
(follow additional instructions).
Low-voltage machines are components for 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 i. a. EN 60204-1).
Low-voltage machines with IP23 protection or less are only intended for outdoor use when
applying special protective features.
The integrated brakes must not be used as safety brakes. It cannot be ruled out that factors
which cannot be influenced, such as oil ingress due to a defective A-side shaft seal, cause
a brake torque reduction.
Transport, storage
Damage must be reported immediately to the forwarder upon receipt; if required,
commissioning must be excluded. Tighten screwed-in ring bolts before transport. They are
designed for the weight of the low-voltage machines, do not apply extra loads. If
necessary, use suitable and adequately dimensioned means of transport (e. g. rope
guides).
Remove transport locking devices before commissioning. Reuse them for further
transport. When storing low-voltage machines, ensure a dry, dust-free and low-vibration
(v
eff
≤
0.2 mm/s) environment (bearing damage while being stored).
