1 – INTRODUCTION
TAKEDO-3VF V20 is a new type of drive with built-in EMC filter, responding to the European Directives
2004/108/EC (EMC) and 2006/95/EC (Low Voltage Equipment).
The inverter can operate only in open loop condition.
This manual provides you with the essential information about the connections in the control panel and the
inverter operation (use of the keypad, parameter and fault message list).
Complete Information for the application can be found in the original INSTALLATION MANUAL from VACON
(inverter series Vacon 20 Cold Plate) available on the site www.it.vacon.com.
2 – SAFETY WARNINGS AND CAUTIONS
For everything related to the warnings about personal safety and prevention of accidental damage to any
product or equipment connected to it, refer to Chapter “SAFETY” of the original INSTALLATION MANUAL
from VACON (inverter series Vacon 20 Cold Plate) available on the site www.it.vacon.com, where you can
also find the “Declaration of Conformity”.
Read this manual carefully and in its entirety before powering up the equipment.
With regard to the specific application on lifts, please consider carefully the following points:
1- The leakage current from the inverter to earth is greater than 30mA, and accordingly, the power
circuit must incorporate a residual current device with I
d
no less than 300mA, type B or type A.
Regulations require that the connection to earth are made with cable of not less than 10 mm² section. If
the residual current device should trip closing the main power switch, do not perform this
operation repeatedly because this could lead to permanent damage to the inverter drive. Check
that the residual current device is rated at least 300mA.
2- To avoid damaging the inverter in case of prolonged stoppages with no power supply, before
restarting the drive proceed as follows:
- If the inverter has been idle for several months, connect it to the power supply for at least 1
hour 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.
3- It is advisable to balance the system at 50%. If balanced at 40%, the UP current under full load will be
greater, and it could be necessary to select a drive with a higher specification than the normally needed
ones.
