2.2 General safety and application instructions for Lenze motors
(According to: Low−Voltage Directive 73/23/EEC)
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
Damages must be reported immediately upon receipt to the forwarder; 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).
Installation
Ensure an even surface, solid foot/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 "Electrical connection").
Use appropriate means to mount or remove belt pulleys and clutches (heating) and cover them with
a touch guard. Avoid impermissible belt tensions.
The machines are half−key balanced. The clutch must be half−key balanced, too. The visible jutting
out part of the key must be removed.
If required, provide pipe connections. Designs with shaft end at bottom must be protected with a
cover which prevents the ingress 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 taken in immediately.
