2.1 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.
Theycomplywith theharmonized standardsof the EN 60034 (VDEO53O)series. Theiruse
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 theinstallationinto machinesas definedin 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, 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 r ing 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).
8
Remove theshipping bracesbefore commissioning. Reusethem forfurthertransports. For
storage of low-voltage machines ensure a dry, dust-free and low-vibration (v
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.

Installation
Ensurean evensurface, solidfoot orflange mountingandexactalignmentifadirectclutch
isconnected.Avoid resonanceswith therotational frequency anddouble mainsfrequency
which may be caused during 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 appropriatetools tomount or removebelt pulleys andclutches (heatgeneration!) and
cover them with a touch guard. Impermissible belt tensions must be avoided (technical
list).
The machinesare half-key balanced.The clutch mustbehalf-key balanced, too.The visible
outstanding part of the key must be removed.
If required,provide pipe connections.Designs with shaft endat bottom mustbe protected
witha coverwhichpreventstheingression offoreign particlesinto thefan. Freecirculation
of thecooling air mustbe ensured. Theexhaust air -also the exhaust airof other machines
next to the drive system - must not be taken in again immediately.
Electrical connection
2
All operations must only be carried out by qualified and skilled personnel when the
low-voltage machine is atstandstill and when the machine isde-energizedand protected
against unintentional restart. This also applies to auxiliary circuits (e.g. brake, encoder,
separate fan).
Check safe isolation from the supply!
If the tolerances in EN 60034-1; IEC 34 (VDE 0530-1) -v oltage ±5 %, frequency ±2 %, wave
form, symmetry - are exceeded, more heat will be generated and the electromagnetic
compatibility will be influenced.
Observe the indications on the nameplate, operating notes, and the connection diagram
in the terminal box.
The connection must ensure a continuous and safe electrical supply (no loose wire ends);
use appropriate cable terminals. The connection to the PE conductor must be safe. The
plug-in connector must be bolt tightly (to stop).
The clearances between blank, live parts and earth must not fall below 8 mm at V
V, 10 mm at V
The terminal box must be clean and dry; foreign particles, dirt and moisture disturb
operation. All unused cable entries and the box itself m ust be sealed against dust and
water. For the trial run without output elements, lock the key. Check brake operation
before commissioning of low-voltage machines with brakes.

Operation
Vibration severitiesv
when the clutch is activated. If deviations from normal operation occur, e.g. increased
temperatures, noises, vibrations, find the cause and, if necessary, contact the
manufacturer. Switch off the machine in problematic situations.
If the drive is exposed to dirt, clean it regularly.
Do not switch off the protection devices, n ot even for trial runs.
Integrated temperature sensors do not provide full protection. If necessary, limit the
maximum current. Connect the function blocks such that the machine switches off after
several seconds of operation at I > I
Shaft seals and bearings have a limited service life.
Regrease the bearings using the relubrication facility while the low-voltage machine is
running. Observe the saponification number. If the greasedrainhole is sealed with a plug
(IP54 driven end; IP23 driven end and non-driven end), remove the plug before
commissioning. Seal the bore holes with grease. Replace the prelubricated bearings (2Z
bearings) afterapprox. 10,000 h-20,000 h, atthelatest however after3- 4 years. Observe
the manufacturer’s instructions.

General safety and application n otes for Lenze controllers
Application as directed
Drive controllers are components which are designed for the installation into electrical
systems or machinery. They are not to be used as domestic appliances, but only for
industrial purposes accordingto EN 61000-3-2. The documentationcontains information
about the compliance with the limit values to EN 61000-3-2.
When installing drive controllers into machines, commissioning of these controllers (i.e.
the star ting of operation as directed) is prohibited until it is proven that the machine
corresponds to the regulations of the EC Directive 98/37/EC (Machinery Directive); EN
60204 must be observed.
Commissioning (i.e. starting of operation as directed) is only allowed when there is
compliance with the EMC Directive (89/336/EEC).
The drive controllersmeet the requirements of the Low-VoltageDirective 73/23/EEC. The
harmonised standards of the EN 50178/DIN VDE 0160 series apply to the controllers.
The technical data as well as the connection conditions can be obtained fr om the
nameplate and the documentation. They must be strictly observed.
2
Warning: Drive controllers are products with restricted availability according to EN
61800-3. Theseproducts can causeinterferences in residential premises.If controllers are
used in residential premises, corresponding measures are required.
Transport, storage
The notes on transport, storage and appropriate handling must be observed.
The climatic conditions according to EN 50178 must be observed.
Installation
The controllers must be installed and cooled according to the regulations given in the
corresponding documentation.
Ensure carefulhandling andavoid mechanical overload.Do notbend any componentsand
do not change the insulation distances during transport and handling. Electronic
components and contacts must not be touched.
Drive controllers contain electrostatically sensitive components which can easily be
damaged byinappropriate handling. Donot damage ordestroy any electricalcomponents
since this could mean hazards to your health!

Safety
General safety and application n otes for Lenze controllers
Electrical connection
When working on live drive controllers, the valid national regulations for the prevention
of accidents (e.g. VBG 4) must be observed.
Carry outthe electrical installationincompliance with thecorresponding regulations (e.g.
cable cross-sections, fuses, PE connection). More detailed information is given in the
corresponding documentation.
Notes about wiring according to EMC regulations (shielding, earthing, filters and cable
routing) are included in the documentation. These notes also apply to CE-marked
controllers. The compliance with limit values required by the EMC legislation is the
responsibility of the manufacturer of the machine or system.
In the case of a malfunction (short circuit to frame or earth fault), Lenze controllers can
cause a DCresidualcurr ent in theprotective conductor. If an earth-leakage circuitbreaker
(residual current device) is used as a protective means in the case of direct or indirect
contact, only an e.l.c.b. of type B may be used on the current supply side. Otherwise,
another protective measure such as separation from the environment through double or
reinforced insulationor disconnection from the mainsby means ofa transformer must be
used.
Operation
If necessary, systems including controllers must be equipped with additional monitoring
and protection devices according to the valid safety regulations (e.g. law on technical
equipment, regulations for the prevention of accidents). The controller can be adapted to
your application. Please observe the corresponding information given in the
documentation.
After a controller hasbeendisconnected from the voltage supply, alllivecomponents and
power connections must not be touched immediately because capacitors can still be
charged. Please observe the corresponding stickers on the controller.
All protection covers and doors must be shut during operation.
NoteforUL approvedsystemswithintegratedcontrollers: ULwarnings arenotes thatonly
apply to UL systems. The documentation contains special UL notes.
Safe standstill
The V004 variant of the 9300 and 9300 vector controllers, the x4x variant of the 8200
vector controllers and the ECSxAxxx axis modules support the ”safe standstill” function,
protectionagainstunexpected start-up,according tothe requirementsof AnnexI No. 1.2.7
of the EC Directive ”Machinery” 98/37/EC, DIN EN 954-1 C ategory 3 and DIN EN 1037.
Observe the notes on the ”safe standstill” function given in the documentation on the
respective variants.
