Mechanical installation
Electrical installation
ƒ Install the product according to the regulations of the corresponding
documentation. In particular observe the section "Operating
conditions" in the chapter "Technical data".
ƒ Provide for a careful handling and avoid mechanical overload. During
handling neither bend components, nor change the insulation
distances.
ƒ The product contains electrostatic sensitive devices which can easily be
damaged by short circuit or static discharge (ESD). Thus, electronic
components and contacts must not be touched unless ESD measures
are taken beforehand.
ƒ Carry out the electrical installation according to the relevant
regulations (e. g. cable cross−sections, fusing, connection to the PE
conductor). Additional notes are included in the documentation.
ƒ When working on live products, observe the applicable national
regulations for the prevention of accidents (e.g. BGV 3).
ƒ The documentation contains information about EMC−compliant
installation (shielding, earthing, arrangement of filters and laying
cables). The system or machine manufacturer is responsible for
compliance with the limit values required by EMC legislation.
Warning: The controllers are products which can be used in category C2
drive systems as per EN 61800−3. These products may cause radio
interference in residential areas. If this happens, the operator may need
to take appropriate action.
ƒ For compliance with the limit values for radio interference emission at
the site of installation, the components − if specified in the technical
data − have to be mounted in housings (e. g. control cabinets). The
housings have to enable an EMC−compliant installation. In particular
observe that for example control cabinet doors preferably have a
circumferential metallic connection to the housing. Reduce openings or
cutouts through the housing to a minimum.
ƒ Only plug in or remove pluggable terminals in the deenergised state!
Commissioning
Operation
Safety functions
2.1−2
ƒ If required, you have to equip the system with additional monitoring
and protective devices in accordance with the respective valid safety
regulations (e. g. law on technical equipment, regulations for the
prevention of accidents).
ƒ Before commissioning remove transport locking devices and keep them
for later transports.
ƒ Keep all protective covers and doors closed during operation.
ƒ Without a higher−level safety system, the described product must
neither be used for the protection of machines nor persons.
ƒ Certain controller versions support safety functions (e.g. "Safe torque
off", formerly "Safe standstill").
The notes on the safety functions provided in the documentation of the
versions must be observed.

Maintenance and servicing
Disposal
ƒ The components are maintenance−free if the required operating
conditions are observed.
ƒ If the cooling air is polluted, the cooling surfaces may be contaminated
or the air vents may be blocked. Under these operating conditions, the
cooling surfaces and air vents must be cleaned at regular intervals.
Never use sharp objects for this purpose!
ƒ Only replace defective fuses in the deenergised state to the type
specified.
ƒ After the system has been disconnected from the supply voltage, live
components and power connections must not be touched immediately
because capacitors may be charged. Please observe the corresponding
notes on the device.
ƒ Recycle metals and plastic materials. Ensure professional disposal of
assembled PCBs.

2.2 Thermal motor monitoring
From software version 8.0 onwards, the 9300 controllers are provided with
2
an I
xt function for sensorless thermal monitoring of the connected motor.
Note!
2
ƒ I
calculates a thermal motor load from the detected motor
currents.
ƒ The calculated motor load is saved when the mains is
switched.
ƒ The function is UL−certified, i.e. no additional protective
measures are required for the motor in UL−approved systems.
ƒ However, I
influences on the motor load could not be detected as for
instance changed cooling conditions (e.g. interrupted or too
warm cooling air flow).
Safety instructions
Thermal motor monitoring
x t monitoring is based on a mathematical model which
2
x t monitoring is no full motor protection as other
2
2.2
2
x t load of the motor is displayed in C0066.
Die I
The thermal loading capacity of the motor is expressed by the thermal motor
time constant (t, C0128). Find the value in the rated motor data or contact
the manufacturer of the motor.
2
The I
x t monitoring has been designed such that it will be activated after
179 s in the event of a motor with a thermal motor time constant of
5 minutes (Lenze setting C0128), a motor current of 1.5 x I
and a trigger
N
threshold of 100 %.
Two adjustable trigger thresholds provide for different responses.
ƒ Adjustable response OC8 (TRIP, warning, off).
– The trigger threshold is set in C0127.
– The response is set in C0606.
– The response OC8, for instance, can be used for an advance warning.
ƒ Fixed response OC6−TRIP.
– The trigger threshold is set in C0120.
Behaviour of the I2 x t monitoring Condition
The I2 x t monitoring is deactivated.
C0066 is set = 0 % and
MCTRL−LOAD−I2XT is set = 0.00 %.
I2 x t monitoring is stopped.
The current value in C0066 and at the
MCTRL−LOAD−I2XT output is frozen.
I2 x t monitoring is deactivated.
The motor load is displayed in C0066.
When C0120 = 0 % and C0127 = 0 %, set
controller inhibit.
When C0120 = 0 % and C0127 = 0 %, set
controller enable.
Set C0606 = 3 (off) and C0127 > 0 %.

The lowered speed / torque characteristic (Fig. 2.2−2) reduces the
permissible thermal load of self−ventilated standard motors. The
characteristic is a line the definition of which requires two points:
ƒ Point : Definition with C0129/1
This value also enables an increase of the maximally permissible load.
ƒ Point : Definition with C0129/2
With increasing speeds, the maximally permissible load remains
unchanged (I

).
In Fig. 2.2−2, the motor speed and the corresponding permissible motor
torque () can be read for each working point (on the
characteristic () ... ). can also be calculated using the values in
C0129/1and C0129/2 (evaluation coefficient "y", 2.2−4).

Protection of persons
ƒ According to their enclosure, Lenze controllers (frequency inverters,
servo inverters, DC speed controllers) and their components can carry a
voltage, or parts of the controllers can move or rotate during operation.
Surfaces can be hot.
– If the required cover is removed, the controllers are used
inappropriately or installed or operated incorrectly, severe damage to
persons or material assets can occur.
– For more detailed information please see the documentation.
ƒ There is a high amount of energy within the controller. Therefore
always wear personal protective equipment (body protection,
headgear, eye protection, ear protection, hand guard) when working on
the controller when it is live.
ƒ Before working on the controller, check if no voltage is applied to the
power terminals.
– the power terminals U, V, W, +UG and −UG still carry dangerous
voltage for at least 3 minutes after power−off.
– the power terminals L1, L2, L3; U, V, W, +UG and −UG carry dangerous
voltage when the motor is stopped.
ƒ Before power−off during DC−bus operation, all controllers must be
inhibited and disconnected from the mains.
ƒ The discharge current to PE potential is > 3.5 mA. In accordance with
EN 61800−5−1
– a fixed installation is required.
– the design of the PE conductor has to be double or, in the case of a
single design, must have a cable cross−section of at least 10 mm
ƒ The controller can only be safely disconnected from the mains via a
contactor on the input side.
ƒ During parameter set transfer the control terminals of the controller
can have undefined states.
– Therefore the connectors X5 and X6 must be disconnected from the
controller before the transfer takes place. This ensures that the
controller is inhibited and all control terminals have the defined state
"LOW".

Safety instructions
Residual hazards
ƒ Controllers can cause a DC current in the PE conductor. If a residual
current device (RCD) or a fault current monitoring unit (RCM) is used
for protection in the case of direct or indirect contact, only one
RCD/RCM of the following type can be used on the current supply side:
– Type B for the connection to a three−phase system
– Type A or type B for the connection to a single phase system
Alternatively another protective measure can be used, like for instance
isolation from the environment by means of double or reinforced
insulation, or isolation from the supply system by using a transformer.
Device protection
Motor protection
ƒ Frequent mains switching (e.g. inching mode via mains contactor) can
overload and destroy the input current limitation of the drive
controller:
– At least 3 minutes must pass between switching off and restarting
the devices EVS9321−xP and EVS9322−xP.
– At least 3 minutes must pass between two starting procedures of the
devices EVS9323−xP ... EVS9332−xP.
– Use the "safe torque off" safety function (STO) if safety−related mains
disconnections occur frequently. The drive variants Vxx4 are
equipped with this function.
ƒ For some controller settings, the connected motor may overheat (e.g.
when operating the DC injection brake or a self−ventilated motor at
low speed for longer periods).
– Using an overcurrent relay or a temperature monitoring device
provides a large degree of protection against overload.
– We recommend to use PTC thermistors or thermal contacts for motor
temperature monitoring. (Lenze three−phase AC motors are equipped
with thermal contacts (NC contacts) as standard)
– PTC thermistors or thermal contacts can be connected to the
controller.
2.3−2
ƒ Drives can attain dangerous overspeeds (e.g. setting of high output
frequencies with motors and machines not qualified for this purpose).
