Warning label
Description
Dangerous electrical voltage
Before working on the inverter, check whether all power connections are dead!
After mains OFF, power connections X100 and X105 carry a dangerous electrical voltage for the
time specified on the inverter!
After switching off the mains voltage wait at least 180s before starting to work on the device.
High leakage current
Carry out fixed installation and PE connection in compliance with standard EN 61800−5−1 !

Hot surface
Use personal protective equipment or wait until inverter has cooled down!
Warning label
Description
Electrostatic sensitive devices
Before working on the inverter, the staff must ensure to be free of electrostatic charge!
2.6 Basic safety measures
WARNING!
Workplace hazards
Possible death or severe personal injury.
Observe all specifications of the corresponding documentation supplied. This is the precondition for
safe and trouble-free commissioning and operation of the inverter and for obtaining the product fea-
tures specified.
Observe the specific safety instructions in this operation manual.
Equip the inverter/drive system with additional monitoring and protection devices if required by na-
tional safety regulations.
Commissioning of the inverter and the related drive system (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); the standard EN 60204 must be observed.
WARNING!
Dangerous electrical voltage
An electrical shock can cause death or severe personal injury.
Apply lockout/tagout procedures whenever possible.
Connect/disconnect all pluggable inverter connections only in deenergised condition!
Only remove the inverter from the installation in completely deenergised state.
NOTICE!
Incorrect inverter installation
Disregarding the following instructions may lead to inverter damage and damage to material assets:
The inverter must be installed and cooled according to the instructions given in the “i500 Mounting and
switch-on instructions“. The ambient air must not exceed pollution degree 2 according to EN 61800-5-1.
Ensure proper handling and avoid excessive mechanical stress. Do not bend any inverter components
and do not change any insulation distances during transport or handling.
NOTICE!
Incomplete or faulty inverter parameterization
Disregarding the following advices may lead to inverter damage and damage to material assets:
Always check if the procedural notes and circuit details described in this document can be adapted to
the particular application.
Refer to the i500 Commissioning manual for the parameterization of technically sophisticated applica-
tions.

2 Safety information
Electromagnetic influences
Lenze · Inverter i510 / i550 - Cabinet · Operation Manual · 0.4 EN · 02/2016 11
2.7 Electromagnetic influences
The i500 inverters can be installed in drive systems of category C2 according to EN 61800-3. These devices can
cause radio interferences in residential areas. In this case, special measures can be necessary.
NOTICE!
Possible electromagnetic interference of drive and control system
Sporadic malfunctions can cause unsafe operation conditions.
Commissioning of the inverter and the related drive system (i.e. starting of the operation as directed) is
only allowed when there is compliance with the EMC Directive (2004/108/EC).
The inverter must be installed in a housing (e.g. control cabinet) to meet the limit values for radio inter-
ferences valid at the site of installation.
2.8 Residual hazards
Consider the following residual hazards in the risk assessment of the application.
WARNING!
Unexpected drive motion
Possible personal injury or property damage.
If there is a short circuit of two power transistors in the inverter, a residual movement of up to 180°/number of
pole pairs can occur at the connected motor! (For 4-pole motor: residual movement max. 180°/2 = 90°).
WARNING!
Dangerous residual voltage –long discharge time!
An electrical shock can cause death or severe personal injury.
After the inverter or the drive system has been disconnected from the supply voltage, all live compo-
nents and power terminals must not be touched immediately because capacitors in the inverter can still
be charged.
Observe the waiting time on the inverter label.
WARNING!
High leakage current
i500 inverters may cause a DC current in the PE conductor.
Possible personal injury due to inappropriate or insufficient protective measures.
If a residual current device (RCD) is used for protection against direct or indirect contact for an inverter
with three-phase supply, only a residual current device (RCD) of type B is permissible on the supply side
of the inverter.
If the inverter 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.

Typecode
16 Lenze · Inverter i510 / i550 - Cabinet · Operation Manual · 0.4 EN · 02/2016
3.3 Typecode
The typecode can be seen on the inverter itself and also over the parameters
Single parts (Only i550)
The single parts (Power unit, control unit, safety) have
their own type code. This codes are also present on the
complete inverter!
Complete inverter: (i510 & i550)
If the inverter was ordered completely an additional
type code reflects the complete inverter.
1. Power unit –type code (P192:5) and serial number (P192:7)
2. Control unit –type code (P192:4) and serial number (192:6)
3. Complete inverter –Product code (P190:1) and serial number(P190:2)

4.1 Mechanical installation
NOTICE!
Possible overheating and reduced service life
Observe the minimal clearances for sufficient ventilation.

For inverter dimensions and mounting options refer to separate manual:
i500 Mounting and switch-on instructions
4.2 Electrical installation
DANGER!
Dangerous electrical voltage
Possible death or severe injuries due to electrical shock.
All installation works on the inverter must only be carried out in the deenergised state.
After switching off the mains voltage, the capacitors in the inverter can still be charged. Observe the
waiting time on the inverter label before commencing work.
CAUTION!
The integral solid state short circuit protection included in the inverter does not provide branch circuit protec-
tion. Branch circuit protection must be provided in accordance with the National Electrical Code and any addi-
tional local codes.
CAUTION!
The inverter (PE) terminals connections must be connected to system earth / ground. Earth / ground impedance
must conform to the requirements of national and local industrial safety regulations and all applicable electrical
codes. The integrity of all earth / ground connections should be periodically checked.
