Safety instructions
General safety and application notes for Lenze controllers
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 2006/42/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.
2
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.
The ambient air must not exceed degree of pollution 2 according to EN 61800−5−1.
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!

Safety instructions
General safety and application notes for Lenze controllers
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, filter, 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 may cause a DC current in the PE conductor. If a residual current device
(RCD) is used for protection against direct or indirect contact for a controller with
three−phase supply, only a residual current device (RCD) of type B is permissible on the
supply side of the controller. If the controller has a single−phase supply, a residual current
device (RCD) of type A is also permissible. Apart from using a residual current device (RCD),
other protective measures can be taken as well, e.g. electrical isolation by double or
reinforced insulation or isolation from the supply system by means of a transformer.
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 terminals 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.

be observed.
Maintenance and servicing
The controllers do not require any maintenance if the prescribed operating conditions are
observed.

Residual hazards
Protection of persons
ƒ Before working on the axis module, check that no voltage is applied to the power
terminals, because
– the power terminals +UG, −UG, U, V and W remain live for at least 3 minutes after
mains switch−off.
– the power terminals +UG, −UG, U, V and W remain live when the motor is stopped.
ƒ The heatsink has an operating temperature of > 70 °C:
– Direct skin contact with the heatsink results in burns.
ƒ The discharge current to PE is > 3.5 mA AC or. > 10 mA DC.
– EN 61800−5−1 requires a fixed installation.
– The PE connection must comply with EN 61800−5−1.
– Comply with the further requirements of EN 61800−5−1 for high discharge
currents!
Device protection
ƒ All pluggable connection terminals must only be connected or disconnected when
no voltage is applied!
ƒ The power terminals +UG, −UG, U, V, W and PE are not protected against polarity
reversal.
– When wiring, observe the polarity of the power terminals!
ƒ Power must not be converted until all devices of the power system are ready for
operation. Otherwise, the input current limitation may be destroyed.
Frequent mains switching (e.g. inching mode via mains contactor) can overload and
destroy the input current limitation of the axis module, if
ƒ the axis module is supplied via the ECSxE supply module and the input current
limitation is activated depending on the DC−bus voltage (C0175 = 1 or 2).
ƒ the axis module is not supplied via a supply module delivered by Lenze.
ƒ the low−voltage supply (24 V) is switched off.
For this reason allow a break of at least three minutes between two starting operations!
Use the safety function ˜Safe torque off˜ (STO) for frequent disconnections for safety
reasons.

Motor protection
ƒ Only use motors with a minimum insulation resistance of û = 1.5 kV,

– Lenze motors meet these requirements.
ƒ When using motors with an unknown insulation resistance, please contact your

ƒ Some settings of the axis module lead to an overheating of the connected motor,
e.g. longer operation of self−ventilated motors with low speeds.
ƒ Use PTC thermistors or thermostats with PTC characteristic for motor temperature
