2 Safety instructions
2.1 General safety and application notes for Lenze controllers
(in accordance with Low−Voltage Directive 2006/95/EC)
For your personal safety
Depending on their degree of protection, some parts of the Lenze controllers
(frequency inverters, servo inverters, DC speed controllers) and their accessory
components can be live, moving and rotating during operation. Surfaces can be
hot.
Non−authorised removal of the required cover, inappropriate use, incorrect
installation or operation, creates the risk of severe injury to persons or damage
to material assets.
For more information, please see the documentation.
High amounts of energy are produced in the controller. Therefore it is required
to wear personal protective equipment (body protection, headgear, eye
protection, ear protection, hand guard).
All operations concerning transport, installation, and commissioning as well as
maintenance must be carried out by qualified, skilled personnel (IEC 364 or
CENELEC HD 384 or DIN VDE 0100 and IEC report 664 or DIN VDE 0110 and
national regulations for the 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.

EDBMB935X EN 8.0
Application as directed
Controllers are components which are designed for installation in electrical
systems or machines. They are not to be used as domestic appliances, but only
for industrial purposes according to EN 61000−3−2.
When controllers are installed into machines, commissioning (i.e. starting of the
operation as directed) is prohibited until it is proven that the machine complies
with the regulations of the EC Directive 98/37/EC (Machinery Directive);
EN 60204 must be observed.
Commissioning (i.e. starting of the operation as directed) is only allowed when
there is compliance with the EMC Directive (2004/108/EC).
The controllers meet the requirements of the Low−Voltage Directive
2006/95/EC. The harmonised standard EN 61800−5−1 applies to the controllers.
The technical data and supply conditions can be obtained from the nameplate
and the documentation. They must be strictly observed.
Warning: Controllers are products which can be installed in drive systems of
category C2 according to EN 61800−3. These products can cause radio
interferences in residential areas. In this case, special measures can be
necessary.
Transport, storage
Please observe the notes on transport, storage, and appropriate handling.
Observe the climatic conditions according to the technical data.
Installation
The controllers must be installed and cooled according to the instructions given
in the corresponding documentation.
Ensure proper handling and avoid excessive mechanical stress. Do not bend any
components and do not change any insulation distances during transport or
handling. Do not touch any electronic components and contacts.
Controllers contain electrostatic sensitive devices which can easily be damaged
by inappropriate handling.
Do not damage or destroy any electrical components since this might endanger
your health!

l
14 EDBMB935X EN 8.0
Electrical connection
When working on live controllers, observe the applicable national regulations
for the prevention of accidents (e.g. VBG 4).
The electrical installation must be carried out according to the appropriate
regulations (e.g. cable cross−sections, fuses, PE connection). Additional
information can be obtained from the documentation.
This documentation contains information on installation in compliance with
EMC (shielding, earthing, filters, and cables). These notes must also be observed
for CE−marked controllers. The manufacturer of the system is responsible for
compliance with the limit values demanded by EMC legislation. The controllers
must be installed in housings (e.g. control cabinets) to meet the limit values for
radio interferences valid at the site of installation. The housings must enable an
EMC−compliant installation. Observe in particular that e.g. the control cabinet
doors have a circumferential metal connection to the housing. Reduce housing
openings and cutouts to a minimum.
Lenze controllers can cause a direct current in the protective conductor. If a
residual current device (RCD) is used as a protective means in case of direct or
indirect contact, only a residual current device (RCD) of type B may be used on
the current supply side of the controller. Otherwise, another protective measure
such as separation from the environment through double or reinforced
insulation or disconnection from the mains by means of a transformer must be
applied.
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
controllers can be adapted to your application. Please observe the
corresponding information given in the documentation.
After the controller has been disconnected from the supply voltage, 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.
Notes for UL−approved systems with integrated controllers: UL warnings are
notes that only apply to UL systems. The documentation contains special UL
notes.
Safety functions
Special controller variants support safety functions (e.g. "safe torque off",
formerly "safe standstill") according to the requirements of Appendix I No. 1.2.7
of the EC Directive "Machinery" 98/37/EC, EN 954−1 Category 3 and EN 1037.
Strictly observe the notes on the safety functions given in the documentation
for the respective variants.

Maintenance and servicing
The controllers do not require any maintenance if the prescribed operating
conditions are observed.
If the ambient air is polluted, the cooling surfaces of the controller may become
dirty or the air vents may be obstructed. Therefore, clean the cooling surfaces
and air vents periodically under these operating conditions. Do not use sharp or
pointed tools for this purpose!
Disposal
Recycle metal and plastic materials. Ensure professional disposal of assembled
PCBs.
The product−specific safety and application notes given in these instructions
must be observed!

2.2 General safety and application notes for Lenze braking units
ƒThese safety notes do not claim to be complete. If any questions or
problems occur, please contact the responsible Lenze representative.
ƒThe braking unit meets the state of the art at the time of delivery and is
generally safe to operate.
ƒThe information in these Operating Instructions refer to the specified
versions of the braking units.
ƒThe braking unit is hazardous to persons, to the braking unit itself, and to
other properties of the operator if
–non−qualified personnel work on and with the braking unit.
–the braking unit is used improperly.
ƒThe procedural notes and circuit details represented within these
Operating Instructions are recommendations, the transferability of which
to the corresponding application has to be checked.
ƒThe braking units must be planned in such a way that if they are
installedcorrectlyand used for their designed purpose in fault−free
operation, they fulfil their function and do not put any persons at risk.
This also applies to the interaction of the braking units with the system as
a whole.
ƒTake additional measures in order to narrow down consequences due to
faults, which can cause danger to persons or damage to material assets:
–Further independent equipment taking over the function of the braking
unit
–Electrical or non−electrical protective devices (locking or mechanical
locks) for the drive system
–Measures concerning the system as a whole
ƒDo not operate the braking unit unless it is in perfect condition.
ƒChanges or modifications of the braking unit are strictly prohibited. In any
case, consultation with Lenze is required.

ƒBefore carrying out operations on the braking unit, check whether all
power terminals are in a deenergised state:
–After power−off the power terminals +UG, −UGand RB1 and RB2 still
carry dangerous voltage for at least 3 minutes.
ƒS1, S2 and S3 have a mains potential!
–Wait for at least 3 minutes before changing over the switches.
