General safety and application information for Lenze capacitor modules
2Safety instructions
2.1General safety and application information for Lenze capacitor modules
(according to Low-Voltage Directive 73/23/EWG)
General
During operation, Lenze capacitor modules can include live parts, depending on their type
of protection. Surfaces can be hot.
If the required cover is removed or the modules are used inappropriately or installed or
operated incorrectly, severe damage to persons or material can occur.
For more information please see the documentation.
All operations concerning transport, installation, and commissioning as 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 the prevention of accidents must be observed).
2
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.
Application as directed
Capacitor modules 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 with the limit values to EN 61000-3-2.
When installing capacitor modules 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. starting of operation as directed) is only allowed when there is
compliance with the EMC Directive (89/336/EEC).
The capacitor modules meet the requirements of the Low-Voltage Directive 73/23/EWG.
The harmonised standards of EN 50178 / DIN VDE 0160 apply to the capacitor modules.
The technical data and information on the connection conditions can be obtained from the
nameplate and the documentation. The instructions must be strictly observed.
Warning: The capacitor modules are products with restricted availability according to
EN 61800-3. These products can cause interferences in residential premises. If capacitor
modules are used in residential premises, corresponding measures are required.
EDBCSXKXXX EN 1.0
Transport, storage
The notes on transport, storage and appropriate handling must be observed.
Observe the climatic conditions required to EN 50178.

Safety instructions
General safety and application information for Lenze capacitor modules
Installation
The capacitor modules must be installed and cooled according to the regulations given in
the corresponding Instructions.
Ensure careful handling and avoid mechanical stress. Do not bend any components and do
not change the insulation distances during transport and handling. Do not touch any
electronic components and contacts.
Capacitor modules contain electrostatic sensitive devices which can easily be damaged by
inappropriate handling. Do not damage or destroy any electrical components since this
means hazards for your health!
Electrical connection
When working on live capacitor modules, the valid national regulations for the prevention
of accidents (e. g. VBG 4) m ust be observed.
The electrical installation must be carried out in compliance with the corresponding
regulations (e. g. cable cross-sections, fusing, PE connection). Additional information can
be obtained from the documentation.
The documentation contains notes for EMC-compliant installation (shielding, earthing,
filters and cable routing). These notes must also be observed when using CE-marked
capacitor modules. The manufacturer of the system or machine is responsible for the
compliance with the limit values required by the EMC legislation.
Operation
If necessary, systems including capacitor modules must be equipped with additional
monitoring and protection devices according to the corresponding safety regulations
(e. g. law on technical equipment, regulations for the prevention of accidents). The
capacitor module can be adapted to your application. Please observe the corresponding
information given in the documentation.
After the capacitor module has been disconnected from the supply voltage, live
components and power connections must not be touched immediately because capacitors
can be charged. Please observe the corresponding labels on the capacitor module.
All protection covers and doors must be shut during operation.
Note for UL-approved system with integrated capacitor modules:
UL warnings are notes which only apply to UL systems. The documentation contains
special UL-related information.
Maintenance and servicing
The capacitor modules are free of maintenance if the prescribed conditions of operation
are observed.
10
In operating areas with polluted ambient air, the cooling surfaces of the capacitor module
can get dirty or the cooling openings can block. Under these conditions a regular cleaning
of the cooling surfaces and cooling openings is essential. Do not use sharp or pointed
objects for this purpose!

Disposal
Recycle metals and plastics. Dispose of printed circuit board assemblies according to the
state of the art.
The product-specific safety and application notes in these Instructions must also be
observed!

2.2Residual hazards
Safety instructions
Residual hazards
Protection of persons
ƒ Before working on the capacitor module, check that no voltage is applied to the
power terminals,
– because the power terminals +UG and -UG at the supply module remain live for at
least 3 minutes after mains switch-off.
– because the power terminals +UG and -UG remain live when the motor is stopped.
ƒ If an error occurs (short circuit to frame or earth fault) a DC residual current may
occur in the PE conductor. If an earth-leakage circuit breaker (residual current
device) is used to protect against direct or indirect c ontact, only the use of an
earth-leakage circuit breaker of type B is permissible on the current supply side. If
not, another protective measure is to be used, as for example, separation from the
environment by double or reinforced insulation or separation from the mains by
using a transformer.
Device protection
ƒ All pluggable connection terminals must only be connected or disconnected when
no voltage is applied.
ƒ The power terminals +UG, -UG and PE are not protected against polarity reversal.
– When wiring, observe the polarity of the power terminals.
ƒ The power may only be converted if the power supply module in the power system
is ready for operation and the charging current limitation i s bridged. Otherwise the
charging current limitation can be destroyed.
ƒ If the charging current limitation is active, a cyclic switching of the mains voltage at
the power supply module can overload and destroy the capacitor. Therefore, at least
three minutes have to pass between two starting operations in case of cyclic mains
switching over a longer period of time.
