2 Safety instructions
2.1 General safety and application notes for Lenze MOBILE devices
Observe the following basic safety instructions when using the MOBILE inverters (devices).
A non−compliance may cause severe injury to persons and/or damage to material assets.
General
ƒFor devices with ECE R10 approval, the ECE regulation no. 100 has to be observed.
For your personal safety
ƒOnly use the devices as directed.
ƒNever commission the devices in the event of visible damage.
ƒNever commission the devices before they have been completely mounted.
ƒOnly separate or plug connectors if the high−voltage mains is switched off and
discharged:
– Power connector (marked with a warning sign on the cover)
– Signal connector
ƒDo not open the housings of the devices.
ƒDo not carry out any technical changes on the devices.
ƒOnly use the accessories approved for the devices.
ƒOnly use original spare parts from Lenze.
ƒObserve all regulations for the prevention of accidents, directives and laws
applicable on the site of installation.
ƒTransport, installation, commissioning and maintenance work must only be carried
out by qualified personnel.
– Observe IEC 364 and CENELEC HD 384 or DIN VDE 0100 and IEC report 664 or DIN
VDE 0110 and all national regulations for the prevention of accidents.
– 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.
ƒObserve all specifications in the documentation.
– Carry out installation and operation in accordance with the documentation.
– This is the condition for safe and trouble−free operation and the achievement of
the specified product features.
– The procedural notes and circuit details described in the documentation are only
proposals. It is up to the user to check whether they can be transferred to the
particular applications. Lenze Schmidhauser does not accept any liability for the
suitability of the procedures and circuit proposals described.

Safety instructions
General safety and application notes for Lenze MOBILE devices

Ò11
EDSMDAG EN 2.0
ƒThe devices and related components can − depending on the degree of protection −
have live, movable or rotating parts during operation.
– Surfaces can be hot.
– Do not remove required covers.
– Do not touch exposed contacts or non−insulated cable ends.
– For more information, please see the documentation.
ƒBefore touching conductive components, ensure isolation from supply by means of
measurement.
The device−specific safety and application notes given in the chapter "Residual hazards"
of this documentation must be observed.
Application as directed
The devices meet the requirements of the Low−Voltage Directive 2006/95/EC. The
harmonised standard EN 61800−5−1 applies to the devices.
The devices marked with E1 are components which are designed for installation in vehicles
(ECE approval). They are not to be used as domestic appliances, but only for industrial
purposes according to EN 61000−3−2.
The technical data and supply conditions can be obtained from the nameplate and the
documentation. They must be strictly observed.
Commissioning (i.e. start of the operation as intended) of devices installed in vehicles is
only permissible if the following has been verified:
ƒThe vehicle corresponds to the valid vehicle standards (e.g. ECE R100, safety
requirements with respect to the electric power train of road vehicles); EN 60204 is
observed.
ƒThe EMC Directive 2004/104/EC (last supplemented by 2009/19/EC) is complied
with.
Transport, storage
Please observe the notes on transport, storage, and appropriate handling.
Observe the climatic conditions according to the technical data.
Installation
You have to mount, connect and cool the devices according to the specifications of the
respective documentation. The equipotential bonding has to be dimensioned sufficiently
and protected against corrosion.
When plug connections are open, the degree of pollution 2 must not be exceeded
according to EN 61800−5−1.
Ensure proper handling and avoid excessive mechanical stress.
Do not touch any electronic components and contacts. The devices contain electrostatic
sensitive devices that can be damaged easily by improper handling. Damaged devices
must not be commissioned.

Electrical connection
When working on live devices, observe the applicable national regulations for the
prevention of accidents and technical measures for occupational safety and health.
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.
The documentation contains notes concerning wiring according to EMC regulations
(shielding, earthing, filters and cable routing). The compliance with limit values required
by the EMC legislation is the responsibility of the manufacturer of vehicles or systems or
machines.
Operation
If necessary, systems including these devices 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 devices can be
adapted to your application by parameter settings. Please observe the corresponding
information given in the documentation.
After the devices have been disconnected from the supply voltage, all live components and
connectors must not be touched immediately because capacitors can still be charged.
Please observe the corresponding stickers on the devices.
Ensure that all protection covers are closed and screwed during operation.
Maintenance and servicing
The devices do not require any maintenance if the prescribed operating conditions are
observed.
The external cleaning of the devices has to be made in the course of the general care of the
vehicles, machines, or systems. Depending on the mounting place and the possible
pollution, the cover sensor has to be cleaned regularly.
Disposal
For a professional disposal and utilisation of the devices, please comply with the valid
regulations, e.g. 2000/53/EC (last amended by 2011/37/EC).

EDSMDAG EN 2.0
2.2 Residual hazards
Protection of persons
ƒSwitch off the high voltage on−board voltage completely before working on the
devices.
ƒBefore working on the device, check whether all power terminals are deenergised
because
– after disconnection, the power terminals U, V and W remain live for at least 5
minutes depending on the system.
– the power terminals +UG, −UG, U, V and W remain live while the motor is rotating.
– Batteries and energy storages can carry hazardous voltage over a longer period of
time.
Device protection
ƒConnect/disconnect all pluggable terminals only in deenergised condition!
ƒDetach the controllers from the installation, e.g. from the motor or mounting wall,
only in deenergised condition!
Motor protection
ƒWith some settings of the controller, the connected motor can be overheated.
– E.g. longer operation of the DC injection brake.
– Longer operation of self−ventilated motors at low speed.
– Wrong frequency or voltage settings in the motor parameters (especially with
120 Hz motors).
Protection of the machine/system
ƒDrives can reach dangerous overspeeds (e.g. setting of high output frequencies in
connection with motors and machines unsuitable for such conditions):
– The controllers do not offer any protection against such operating conditions. Use
additional components for this purpose.
Symbol Description
ÞLong discharge time: All power terminals remain live for a few minutes after mains disconnection!
The duration is given under the warning symbol on the device.
}High leakage current: Carry out fixed installation and PE connection according to EN 6180051!
'Electrostatic sensitive devices: Before working on the device, the personnel must be free of
electrostatic charge!
|Hot surface: Risk of burns! Hot surfaces should not be touched without wearing protective gloves.
}
¶
