2 Important Notes
2.1 Safety Tips
•Depending on the class of their isolation, the surface of VVVF controllers can possibly be in circuit,
bare or hot.
•Unadmitted removal of parts of the casing, improper use, wrong installation or operation are
dangerous to life, injurious to health or can cause damages.
•Every work in connection with transport, installation and initiation as well as servicing is to be
executed by competent persons labour.
•Skilled labour according to this basic safety tip includes field personnel familiar with the mounting,
installation, initiation and operation of this product and qualified for this work.
•VVVF controllers are components of electric devices or machines. Their initiation, i.e. start of the
destined operation, is subject to keeping to the EMC-regulations (89/336/EC).
•Technical specifications and information concerning conditions of connecting are to be read from
the type label and the documentation and are by all means to be adhered to.
2.2 Retrofitting old systems
Before retrofitting a VVVF controller in an existing elevator ask your motor supplier, whether the
isolation of the motor-winding is suitable for VVVF controller-operation.
If the motor originally has not been conceived for VVVF controller-operation, we recommend,
however, to install an external inductor in addition to the integrated one. If you are not sure, please
contact us. We will be pleased to advise you.
2.3 Installation of the VVVF controller
Please pay your special attention to the signal lines and power lines that they do not cross over each
other nor lie in parallel in a mutual cable duct. For EMC-reasons, it is recommendable to separate
them to prevent interference effects.
For using the F1..F7 units outside the control cabinet, appropriate terminal covers with strain relief are
available from us. In the other VVVF devices these are already included.
For finger touch-proof operation outside of the switching cabinet, the optional terminal covers must be
installed.
Install the braking resistor outside the cabinet, in order to avoid unnecessary heat dissipation to the
electronic devices inside the cabinet.

9.581.140-6 Page: 12
2.4 Installation of the Brake Resistor
Important note !
Due to the heat dissipation the brake resistor should always be fixed in the range of non-flammable
bases. Above the brake resistor there must not be any inflammable objects. This is particularly
important if devices with integrated brake resistor are installed.
For proper ventilation there should be at least 50 cm space above and below the brake resistor.
The brake resistor must be mounted in such a way, that the cable exit is on a side.
If the above mentioned recommendations are not considered, FIRE RISK exists !
It is recommended, to brake resistor with integrated temperature monitoring. These are optionally
available at RST.
For this, please refer to the following wiring diagram.

In the case of devices with integrated brake resistor as well as external brake resistors with
permissible ON-times > 20% or a higher power, this monitoring function is already included as a
standard. For details, refer to Chapter 4.2.1.5.

9.581.140-6 Page: 13
2.5 See to sufficient ventilation of the cabinet
Above and below the VVVF controller, leave space of at least 10 cm height, in order to provide
sufficient ventilation.
Moreover, use a enclosure with perforated floor and ceiling, most probably your supplier of enclosures
will offer appropriate pre-fabricated metal sheets. This will support ventilation and prevent thermal
failure of electronic parts even in midsummer. If necessary, forced ventilation must be provided in
the enclosure.
Temperature in the enclosure must be kept below 50°C at any operational situation. Failure or
malfunction of the electronics will not be under warranty, if this temperature is exceeded.
Inverters with integrated brake resistor must be fixed outside the cabinet. Please refer the safety hints
section 2.4.
2.6 Connection of contactor coils
To avoid inductive voltage peaks during contactor operation, they should be provided either with
varistors or RC elements.
2.7 Contactor mounting plate
•The mounting plate must be well grounded
•In the case of a very high unit performance where contactor operation may cause significant
mechanical vibration in the enclosure, the contactors should be equipped with rubber-metal
vibration dampers.
2.8 Earthing
Due to the leakage currents of the integrated line filters (> 3.5 mA), the frequency converters
must be grounded by a protective conductor before commissioning (according to EN 50178 resp. EN
60335).
In this case, either
• the cross-section of the protective conductor must be > 10 mm2
• the protective conductor must be monitored for interruption
• an additional protective conductor must be installed

9.581.140-6 Page: 14
2.9 Shielding
•On principle, use screened cables and lines only, for every connection to outside of the cabinet,
i.e.:
- Motor cable
- Encoder cable
- Brake resistor cable
- Motor PTC resistor cable (if wired on VVVF controller)
- DCP cable
- Cable for shaft copying of control
•The cable from the encoder is to be screened up to the plug in the VVVF controller.
•The motor cable should be installed separately from the other cables, if possible.
•To obtain a proper earth connection, the harness shields of the cables must be connected to the
PE base plate by means of metal clamps. The shields of the cables must be in firm contact with
the clamp
2.10 Earth-leakage circuit-breaker
•The elevator should not be operated via an earth-leakage circuit-breaker, as the leakage current
of the interference suppression capacitors contained in the VVVF controller and the interference
suppression filter could operate this circuit-breaker. Should it nevertheless be inevitable to install
an earth-leakage circuit breaker due to a special situation concerning the elevator, only use circuit-
breakers admitted to VVVF controller-operation (type B, DIN-VDE 0644-100).
2.11 Motor protection by ptc-thermistor
The evaluation of the motors ptc-thermistor is integrated in the software. It must be activated in the
menu. As a standard, the evaluation is deactivated.
2.12 Motor protection switch
Motor protection switches on principle do not suit a VVVF-controlled elevator drive and should
therefore not be applied

9.581.140-6 Page: 15
2.13 Mains feedback
Three-phase commutation reactors (NEDs) must be provided between the mains and the frequency
converter to reduce the low-frequency mains effects.
2.14 Energy recovery
Motor protection switches on principle do not suit a VVVF-controlled elevator drive and should
therefore not be applied.
To optimize any potential mains feedback, in particular if group drives are used, we recommend the
use of three-phase commutation reactors. These are available at RST Elektronik upon request.
2.15 Reactive current compensation
If capacitors compensating reactive current were connected directly to the motor connectors, they
would destroy the VVVF controller, as due to the high switching frequency of the transistors a would-
be short circuit would be created.
Reactive current compensation, if at all, is to be executed at the mains connection of the building, but
never in the machine room.
3 Warranty
As for warranty please refer to our General Conditions. Demands going beyond these conditions are
subject to a special agreement.

Notes:
At travel speeds of more than 1,6 m/s and/or travel time of more than 30 seconds apply braking
resistors of higher capacity respectively pulse duty factor OD.
When calculating the braking resistor please take note that the installation efficiency is very important.
The above listed braking resistors are for standard installations. Further calculations for specific
installations on request.
The permissible duty cycle can be calculated approximately as follows:
Example: For an elevator with a rise of 12 m and a driving speed of 1 m / s, the permissible duty cycle
of the braking resistor is 10 %.
