1 Safety information

1.1 General safety and application notes for Lenze controllers

(according to Low-Voltage Directive 73/23/EEC)

1. General

Lenze controllers (frequency inverters, servo inverters, DC controllers) can carry a voltage or parts of the controllers can rotate during operation. Surfaces can be hot.
If the required cover is removed, the controllers are used inappropriately or installed or operated incorrectly, severe damage to persons or material assets can occur.
For more information please see the documentation.
All operations concerning transport, installation, and commissioningas well as maintenance must be carried out by qualified, skilled personnel (IEC 364 and CENELEC HD
384 or DIN VDE 0100 and IEC report 664 or DIN VDE 0110 and national regulations for t he prevention of accidents must be observed).
According to this basic safety information qualified, skilled personnel are persons who are familiar with the assembly, installation, commissioning, and operation of the
product and who have the qualifications necessary for their occupation.

2. Intended use

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 according to EN 61000-3-2. The documentation contains information about the compliance of the limit values with EN 61000-3-2.
When installing controllers into machines, commissioning of the drive controllers (i.e. the starting of operation as directed) is prohibited until it is proven that the machine
corresponds to the regulations of the EC Directive 98/37/EG (Machinery Directive); EN 60204 (VDE 0113) must be observed.
Commissioning (i.e. starti ng of operation as directed) is only allowed when there is compliance with t he EMC Directive (89/336/EEC).
The drive controllers meet the requirements of the Low-Voltage Directive 73/23/EEC. The harmonised standards EN 50178/DIN VDE 0160 a pply to t he controllers.
The technical data as well as the connection conditions can be obtained from the nameplate and the documentation. The instructions given must be strictly observed.
Warning: Controllers are products with restricted availability according to EN 61800-3. These products can cause interferences in residential premises. If controllers are
used in residential premises, corresponding measures are required.

3. Transport, storage

The notes on transport, storage and appropriate handling must be observed.
Climatic conditions according to EN 50178 apply.

4. Installation

The controllers must be installed and cooled according to the regulations given in the corresponding Instructions.
Ensure careful handling and avoid mechanical overload. Do not bend any components and do not change the insulation distances during transport and storage. Electronic
components and contacts must not be touched.
Controllers contain electrostatically sensitive components which can easily be damaged by inappropriate handling. Do not damage or destroy any electrical components
since this could mean hazards for your health!

5. Electrical connection

When working on live controllers, the valid national regulations for the prevention of accidents (e. g. VBG 4) must be observed.
The electrical installation must be carried out in compliance with the corresponding regulations (e.g. cable cross-sections, fuses, PE connection). Additional notes and
information can be obtained from the corresponding Instructions.
The Instructions contain notes concerning wiring according to EMC regulations (shielding, earthing, filters and cable routing). These notes must also be observed when
using CE-marked controllers. The compliance with limit values required by the EMC legislation is the responsibility of the manufacturer of the machine or system.

6. Operation

If necessary, systems including controllers must be equipped with additional monitoring and protection devices according to the applying safety regulations (e.g. regulation
for technical equipment, regulation for the prevention of accidents). The controller can be adapted to your application. Please observe the corresponding information given
in the Instructions.
After a controller has been disconnected from the voltage supply, all live components 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.

Note for UL-approved systems with integrated controllers: UL warnings are notes which only apply to UL systems. The Instructions give UL-related information.

7. Safe standstill

The variant V004 of 9300 and 9300 vector, the variant Bx4x of 8200 vector controller and the axis controller ECSXA064 support the function ”Safe standstill”, protection
against unexpected start, according to the requirements of Annex I No. 1.2.7 of the EC Directive ”Machinery” 98/37/EG, DIN EN 954-1 category 3 and DINEN 1037. Please

Lenze low-voltage machinery

1.2 General safety and application notes for Lenze low-voltage machinery

(in conformity with the Low-Voltage Directive 73/23/EEC)

1. 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 outbyskilled,responsible technical personnel (observe EN 50110-1(VDE0105-100);IEC60364). Improper handling can cause severe injuries
or damages.
Synchronous machines induce voltages at open terminals during operation.

2. Application as directed

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).
The enclosures ≤IP23 are by no means intendedfor outdooruse. Air-cooled designsare ratedforambienttemperaturesbetween -15 °C and -10 °Cand+40°C and altitudes
≤ 1000 m a.m.s.l., from -20 °C to +40 °C without brake or with spring- operated brake, with separate ventilation or self ventilation, 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 machines are components for the installation into machines as defined in the Machinery Directive98/37/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 ruled out that factorswhich cannot be influenced, such as oil ingression because of a defective A-side
shaft seal, cause a torque reduction.

3. 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 brace before commissioning. Reuse it for further transports. For storage of low-voltage machines ensure a dry, dust-free and low-vibration
(v

≤ 0.2 mm/s) environment (danger of bearing damage at rest). Measure the insulation resistance before commissioning. If the values are ≤ 1kΩ per volt of rated

rms

voltage, dry the winding.

4. Installation

Ensure an even surface, solid foot or flange mounting and exact alignment if a direct clutch is connected. Avoid resonances with the r otational frequency and double mains
frequency which maybe caused by the assembly. Turn rotor by hand, listen for unusual slipping noises.Check the direction of rotation when the clutchis not active (observe
section 5).
Use appropriate tools to mount or remove belt pulleys and clutches (heat generation!) and cover them with a touch guard. Impermissible belt tensions must be avoided
(technical list).
The machines are half-key balanced. The clutch must be half-key balanced, too. The visibly protruding part of the key must be removed.
If required, provide pipe connections. Mounting positions with shaft end at top must be protected with a cover which avoids the ingression 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 immediately taken in
again.

5. Electrical connection

All operations must be carried outonly by qualified and skilled personnel when the low-voltagemachineis at standstill and whenthemachine is de-energized and 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) - voltage ±5 %, frequency ±2 %, waveform, 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 screwed up tightly (to stop).
The clearances between bare, live parts and earth must not fall below: 8 mm at V
The terminal box must be clean and dry; foreign particles, dirt and moisture affect operation. All unused cable entries and the box itself must be sealed against dust and
water. For the trial run without output elements, lock the key. Check brake opera tion before the commissioning of low-voltage machines with brakes.

6. Operation

Vibration severities v
e.g. increased temperature, noise, vibration, 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, not even for trial runs.
Integrated temperature sensors do not provide full protection. If necessary, limit the maximum current. Connect the function blocks to the option switch-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 grease drain hole is sealed with
a plug (IP54 drive end; I P23 drive end and non-drive end), remove the plug before commissioning. Seal the bore holes with grease. Replace the prelubricated bearings
(2Z-bearings) after approx. 10.000 h - 20.000 h, at the latest however after 3 - 4 years. Observe the manufacturer’s instructions.

Safety information

Residual hazards, Layout of the safety instructions

Protection of
persons

• Before working on the motec or opening the housing, check that no voltage is appli ed. Wait for at least 3 minutes, since after mains switch-off

the power terminals U, V, W; BR0, BR1, BR2 and the pins of the FIF interface remain live.

– A fter you have opened the motec check whether the power terminals L1, L2, L3; U, V, W; BR0, BR1, BR2, relay outputs K 11, K12, K14 and

pins of the FIF interface are not live an y more.

– Even if the motec is separated from the mains, the relay outputs K11, K12, K14 can remain live!

• If you use the not fail-safe functi on “Selection of direction of rotation” via the digital signal DCTRL1- CW/CCW

(C0007 = -0- ... -13-, C0410/3 ≠ 255):

– I n the event of an open circuit or failure of the control voltage, the drive can change its direction of rotation.

• If you use the function ”Flying-restart circuit” (C0142 = -2-, -3-) with machines with a low moment of inertia and a minimum friction:

– A fter controller enable in standstill, the motor can start for a short time or change its direction of rotation for a short time.

• The motec heatsink temperature is > 60 °C:

– Direct skin contact with the heatsink results in burnings.

Controller
protection

• 8200 motec 3 ... 7,5 kW (E82MV302_4B, E82MV402_4B, E82MV552_4B, E82MV752_4B):

– Cyclic connection and disconnection of the controller supply voltage at L1, L2, L3 can exceed and destroy the input current limit!
– In case of cyclic mains switching over a longer period of time three minutes ha ve to pass between two starting operations!

• Depending on the controller settings, the co nnected motor can be overheated:

– at, for instance, longer DC-braking operations.
– at longer operation of self-ventilated motors at low speed.

Overspeeds • Drives can reach dangerous overspeeds (e.g. setting of inappropriately high field frequencies):

– The controllers do not offer any protection against these operating conditions. For this, use additional components.
