1 – INTRODUCTION
TAKEDO ENERGY is a device able to recover, directly on the mains, the energy normally dissipated by the
braking resistor in lift systems driven by an inverter.
Its built-in LCL filter can reduce the current harmonic contents, to be compliant to the EN 12015 standard, for
low frequency harmonics.
2 – SAFETY WARNINGS AND CAUTIONS
Detailed informations are available inside the VACON original manual (NXP series),
on www.vacon.com website.
Read carefully this manual before powering the unit , following the procedures step by step .
2.1 CAUTIONS
To avoid damaging the inverter in the event of prolonged stoppages with no power supply, before restarting
the drive, connect it to the power supply for at least 1 hour, with no commands to the lift system, in such a
way as to recharge the bus capacitors.
If the inverter has been idle for more than one year, supply it for 1 hour with a level of voltage 50% lower
than the nominal input voltage, and then supply it with the nominal input voltage for 1 hour.

4 – OPERATION PRINCIPLE
When the lift motor is pulled by the load (for example running upward with empty car or downward with full
load in the car, or in any case of favorable weight) all the energy of the excess weight that descends to the
ground floor must be dissipated to prevent the escape of the weight itself.
Normally in a lift system with speed controlled by an inverter, all the energy generated by the motor driven by
the load is dissipated via a braking resistor, which converts the energy into heat. The regenerated energy
depends, besides the weight, on the system type, on the motor type, on the gear type, etc. ..
TAKEDO ENERGY is a device which “returns” the excess energy to the mains: in this way, rather than heat
the environment, it reduces the consumption, since the recovered energy feeds the other loads of the
system: operation, brake, car light, etc..; only the excess is fed back into the supply network for supplying
other building utilities.
With the objective of ensuring maximum energy savings, TAKEDO ENERGY has an internal system to
reduce power consumption in stand-by from about 19W to 3W.
After a minute from the motor contactors dropping, the system turns off; it will turn on again, ready to recover
energy, at the next activation of a new command.

5 –CONNECTIONS
5.1 WARNINGS
1 - Do not power the device without having done the EARTH cable connection.
2 - To increase the security of the device (especially against over voltages due to weather events), three
fuses (one for each phase) are provided in series with the input terminals of the mains supply (their size
depends on the device size).
3 - The device must be connected as indicated in 5.3 and 5.4, following the application diagram in Chapter 6.
An incorrect connection may cause damages.
4 - Perform the wiring as described in Section 5.2 to avoid EMC problems.
5.2 WIRING RULES
In order to avoid problems related to EMC, wiring must be treated according to the following guidelines :
1 - The cable connection between the bus of the main inverter and TAKEDO ENERGY should be as far
away as possible from any other wiring (although shielded) and never parallel. If the wires are crossed,
should be arranged to form a 90 degrees angle.
2 - The earth and the shield of the cable that connects TAKEDO ENERGY to the main inverter BUS must
be connected, inside the main inverter, to the same terminal in which the building earth cables are
connected.
3 - The cable that connects TAKEDO ENERGY to the mains must be far away from the power cable that
connects the main inverter to the motor and from the cable that connects the braking resistor to the
main inverter (50 cm at least).
5.3 POWER CONNECTIONS
MAINS wiring The mains must be connected to terminals L1-L2-L3 of TAKEDO ENERGY, following
the drawing shown at Chapter 6.
It is not necessary to respect the phase sequence.
BUS wiring The terminals B + and B-must be connected to the BUS of the main inverter.
Should NOT be connected in parallel with the braking resistor.
Normally the inverters have a resistor terminal connected to the positive terminal of the
BUS. The negative of the BUS is usually a terminal with no other connections.
With motor inverter powered , between the positive and negative BUS terminals there
are 500Vdc ÷ 650Vdc.
EARTH wiring TAKEDO ENERGY has two earth wires that must be both connected : one on the mains
EARTH cable and the second one on the cable connected to the motor inverter BUS.
SHIELD The only shield to be connected is on the cable connected to the motor inverter BUS.
Please read carefully the notes in section 5.2
5.4 CONTROL CONNECTIONS
RUN command INPUT to terminals RUN – RUN, to be connected to a “voltage free” contact of a run
contactor.
The command must be activated BEFORE the lifting of the mechanical brake and
disabled AFTER the dropping of the mechanical brake.
FAULT relay
(OPTION)
If the NXOPTA2 Board is provided, at output terminals 21-22-23 is available a switching
contact of a relay, powered when the TAKEDO ENERGY is ready to run.
In case of malfunction or failure this relay is disabled.

IMPORTANT
If the existing motor inverter is provided with an INSIDE FILTER,
you must install an external added filter, so that the connection of
TAKEDO ENERGY can be carried out as shown in the figure.
