1 INTRODUCTION
SIEMENS V20 is an inverter with a specialized software in hydraulic systems, which controls only the up-
ward travel.
These inverters SIEMENS can be applied to both pump units of the old generation, and pump units most re-
cent and modern.
The advantages are:
Absence of starting current peaks. The maximum starting current is the rated current In.
Power factor correction. Cosϕ≥0.98.
Power saving.
Comfort optimization.
Setting parameters of high/low speed.
Maximum power absorbed from the network adjustable, to reduce the power costs.
Absence of braking resistors.
For further information regarding the functions of the inverter Siemens V20, refer to the relevant manu-
als on the website.

2 SAFETY INSTRUCTIONS AND PRECAUTIONS
Read all of this manual before powering the equipment, following step by step the procedures.
2.1 SAFETY INSTRUCTIONS
Carefully follow the procedures given below, to prevent the risk of serious accidents.
1- The leakage current from the inverter to earth is greater than 30mA, therefore a differential
switch with Id of at least 300mA, type B or type A, must be provided. Regulations require the use
of a cable with a section of at least 10 mm² for the earth connection. If the differential switch trips
when the main power switch is closed, do not repeat the operation in succession, because
the inverter could become permanently damaged.
2- If the parameters are incorrect, the inverter can cause the motor to rotate at a speed higher than
synchronous speed. Do not run the motor beyond its electrical and mechanical limits. The installer is
responsible for ensuring that movements occur in safe conditions, without exceeding the specified
operating limits.
3- Risk of electrocution. Power on the inverter only with the front cover fitted. NEVER remove the cover
during operation. Before carrying out any operation on the equipment, disconnect the power supply
and wait a few minutes for the internal capacitors to discharge.
4- The inverter must always be connected to the mains. In case of an interruption, wait at least 1 mi-
nute before reconnecting. RECONNECTING WITHOUT WAITING LONG ENOUGH WILL DAMAGE
THE INVERTER.
5- Do not use an oscilloscope or similar instruments to test the internal circuits of the inverter. This type
of operation must be performed only by specialized personnel.
2.2 PRECAUTIONS
Carefully follow the procedures given in the manual to avoid the risk of damaging the inverter.
1- Do not connect the equipment to a voltage higher than that permissible. An excessive voltage can
cause permanent damage to the internal components.
2- To avoid damaging the inverter in case of prolonged stoppages with no power supply, before
restarting proceed as follows:
- If the inverter has been idle for several months, connect it to the power supply for at least 1
hour in order to regenerate the bus capacitors.
- If the inverter has been idle for more than one year, power it for 1 hour at 50% less than the
nominal voltage, and then for 1 hour at nominal voltage.
3- Do not connect capacitors to the inverter outputs.
4- Before resetting an inverter fault, carefully check what caused activation of the protection.
5- Use an inverter with rated current equal to or higher than the motor rated current.

3.1.5.2 Star-delta connection of the motor
V20 single-phase inverter requests a 1AC 230V connection in input.
The output connection is 230V 3AC and is must be carried out consistently with the motor connection, con-
sidering that the supply voltage will never exceed the input voltage
For instance, select delta connection if either a 230 / 400 V motor on a 400 V inverter or a 120 / 230 V motor
on a 230 V inverter is supposed to operate at 87 Hz instead of 50 Hz.

4 EMC-COMPLIANT INSTALLATION (EMC)
Together with a system configuration in conformity with EMC standards (see norms EN 61000-6-2,
EN61000-6-4, EN60204-1), the line filters limit the conducted interference emitted by the Power Modules to
limit values according to standard EN61800-3.
For PM this is obtained by mains integrals filters.
The PM with a suitable line filter shall correspond to the category C2 for domestic installations, provided that:
1. they are installed and put into service by a specialist (according to the definition given by the norma-
tive), in compliance with the limit values for electromagnetic compatibility
2. the below shown additional requisites are respected:
Connection by use of a shielded cable at reduced capacity
Motor cable shorter than 25 m
Pulse frequency ≤ 4 kHz
Current ≤ nominal input current in the technical data
The shield connection kit allows easy and efficient connection of the necessary shield to achieve EMC-
compliant installation of the inverter. If no shield connection kit is used, you can alternatively mount the de-
vice and additional components on a metal mounting plate with excellent electrical conductivity and a large
contact area. This mounting plate must be connected to the cabinet panel and the PE or EMC bus bar.
The following diagram shows an example of EMC-compliant installation of the inverter frame size C.
Shielding method
The following illustration shows an example with and without the shielding plate.
EMC-compliant cabinet design

Siemens V20_EN_rev01-08032019.docx 4-7
The most cost-effective method of implementing interference suppression measures within the control cabi-
net is to ensure that interference sources and potentially susceptible equipment are installed separately from
each other.
The control cabinet has to be divided into EMC zones and the devices within the control cabinet have to be
assigned to these zones following the rules below.
The different zones must be electromagnetically decoupled by using separate metallic housings or
grounded separation plates.
If necessary, filters and/or coupling modules should be used at the interfaces of the zones.
Cables connecting different zones must be separated and must not be routed within the same cable
harness or cable channel.
All communication (e.g. RS485) and signal cables leaving the cabinet must be shielded.

Siemens V20_EN_rev01-08032019.docx 5-8
5 BRAKING RESISTORS
The inverter handle only the upward travel in consequence of that, there are not cur-
rents generated and MUST NOT BE INSTALLED ANY BRAKING RESISTOR.
The downward direction is regulated by hydraulic valve. To adjust downward parameters, refer to the manual
of the installed valve.

7 POWER WIRING
7.1 POWER CIRCUIT CONNECTION
All electrical wirings have to be done, respecting the rules shown in the table below:
L1; L1
Mains power supply input
Connect the mains power supply input phases in any order.
U; V; W
Inverter output
Connect the three output phases to the contactors, then to the
motor.
PE
Earth (protection)
Connect to the building's earth system.
7.2 SAFETY INSTRUCTIONS
1- Do not power the inverter without first making the earth connection.
2- To increase inverter protection (especially against overvoltage due to electrical storms), three extra-
fast-blow fuses (one for each phase) can be installed in series with the supply mains input terminals.
The fuses must be rated according to the various sizes. The set of fuses, complete with protection
box, can be supplied on request (not indispensable!).
3- To avoid permanently damaging the inverter, do not connect braking resistors with resistance or
power ratings lower than those given in the table.
4- The inverter drive must be connected “upstream” of the power contactors.
5- Wire earth connections and masses correctly to avoid problems of EMC interference.
6- Pay particular attention to the power connection; if the input and output are inverted, the in-
verter will inevitably be damaged.
7.3 RULES FOR EMC COMPLIANT MOTOR - INVERTER WIRING
For a correct wiring of the group INVERTER - ENGINE, in addition to the procedure described in Chapter 4,
about electromagnetic compatibility, follow the steps below:
1- The inverter and motor must be connected directly to the building's earth system.
2- The power cables for the inverter/contactors and contactors/motor connection must be as short as
possible, shielded four-core (three phases plus yellow/green earth wire), or four unshielded cables
bound together and inserted in a raceway or a metal pipe connected to earth. In other words, there
must be an earth wire as close as possible to the power wires in the same cable or in the same pipe.
If shielded cable is used, continuity of the earth braid between the inverter/contactors and contac-
tors/motor section must be ensured.
It is advisable to connect the shielding to earth at both ends by means of a U-clip or with special ter-
minals.
If the shield cannot be connected with a U clip inside the motor terminal block, it must be earthed on
the frame before entering the terminal block.
3- Even if it is not essential, a good engineering way provides to have a shielded cable also in the pow-
er line in input, in order to prevent that irradiated noises are brought out, by means this cable.
4- The inverter power cables (input and output) and control cables must be kept as far apart as possi-
ble and must not run parallel, even if shielded; if the cables cross, they must be arranged at an angle
of 90°.
5- Irrespective of the connection to the building's earth system, the motor frame MUST be connected to
the cable shield and to the yellow/green earth wire inside the shielded cable.
6- The inverter emits radiated interference, which can therefore be picked up and carried outside the
panel by the cables, especially by flexible cables which radiate the interference into the lift shaft. If
this problem is to be avoided, the connections between the panel and the inverter must be made us-
ing shielded wires with shield connected to earth at both ends. Shielded cables must not be used

Siemens V20_EN_rev01-08032019.docx 7-4
without the shield connected to earth, as in this case any interference will be greater than with an
unshielded cable.
Any free or unused wires in a multicore cable must be connected to earth at both ends.
7- Any cable, for control or external connections for the shaft and lift car, must never run near and par-
allel to the power cable, even if shielded; if parallel routing cannot be avoided, they must be in sepa-
rate metal raceways.
8- All earth connections must be as short and wide as possible.
9- To avoid unwanted tripping of the differential switch:
Make the power connection as short as possible
Use suitable differential switches (type A or B 300mA)
When possible, reduce the inverter carrier frequency: in fact, as lower is the frequency, is
greater the motor noise, but with less current leakage to earth and less EMC interference; so
the motor windings are less stressed.

8 PROGRAMMING THROUGH PC
For the SIEMENS V20 inverter, is not available an interface tool for parameters programming directly via PC;
therefore it is necessary to proceed in case of parameters values modification by using the keypad and the
screen supplied on the front of the inverter (BOP).
9 PROGRAMMING THROUGH KEYBOARD AND MENU
9.1 EXPANSION PORT (Optional)
The expansion port (optional) is designed for connecting the inverter to the external option module
- BOP Interface Module or Parameter Loader, in order to realize the following functions:
Operating the inverter from the external BOP
Cloning parameters between the inverter and a standard MMC / SD card
Powering the inverter from the Parameter Loader, when mains power is not available.
9.2 THE BUILT-IN BASIC OPERATOR PANEL (BOP)
The Basic Operator Panel BOP is an operator panel with six keys and a backlight display unit. The BOP is
inserted on the Inverter V20.
The BOP supports the following functions:
Input of parameters and activation of functions
Display of operating modes, parameters, alarms and faults
WARNING: DON’T USE THE BUTTONS 0/1.
The buttons 0/1 bypass the panel signals, so the starting and the stopping of the inverter and the motor
are under exclusive control and responsibility who activate them.
