IMPORTANT INFORMATION
This quick start guide represents only an excerpt of the VAU 1.1/1-AC operating instructions. The latter should be read
thoroughly before initial start-up.
The quick start guide contains safety instructions and helps the user to put the basic model of the frequency converter (FC)
into operation and to operate it with the default settings.
The frequency converter can only be operated safely if the required ambient conditions, see chapter 4, have been complied
with.
Gebrüder BECKER GmbH will not be liable for damage resulting from the non-observance of these operating instructions.
These operating instructions form a part of the product. They apply exclusively to the frequency converter of the VAU
series by Gebr. Becker GmbH. Store the operating instructions well accessible for all users near the frequency converter.
i
IMPORTANT INFORMATION
Any work concerning transport, installation and commissioning as well as maintenance may only be carried out by qua-
lified specialists (observing IEC 364/CENELEC HD 384/DIN VDE 0100 and IEC 664/DIN VDE 0110 and national accident
prevention regulations).
Qualified personnel in the meaning of these operating instructions are electricians who are familiar with the installation,
assembly, commissioning and operation of the frequency converter and the related risks. In addition they will have know-
ledge of the relevant standards and regulations based on their technical training.
WARNING
Mortal danger from fire or electric shock!
Death or serious injury!
Only use the frequency converter as intended.
Do not perform any alterations on the frequency converter.
Only use spare parts and accessories sold or recommended by the manufacturer.
During assembly ensure adequate distance to adjacent components.
CAUTION
Risk of burns from hot surfaces!
Serious skin burns from hot surfaces!
The heat sink and all other metal components can heat up to temperatures exceeding 70°C.
Adequate distance to adjacent components must be kept during assembly.
When working on the components ensure sucient cooling down times.
1.3 COMMISSIONING INFORMATION
Electrical connection
Frequency converters are equipment items for use in industrial high voltage systems and are operated with voltages which
may result in serious injury or death upon contact.
They may only be installed or worked on by qualified electricians and with the equipment switched to zero potential. These
individuals must always have access to the operating instructions which must be consistently observed by them.

4BECKERVAU 1.1/1AC
DANGER
Mortal danger from electric shock!
Death or serious injury!
Switch the frequency converter to zero potential and protect it against reactivation.
The following terminals may still carry dangerous voltages even with the motor at rest:
• mains connection terminals 1X1: PE, N, L
• motor connection terminals X2: U, V, W
• connection terminals X6, X7: relay contacts relay 1 and 2
• PTC/bimetallic switch connection terminals 1X6: T1/T2
i
IMPORTANT INFORMATION
• When working on live frequency converters the applicable national accident prevention regulations (e.g. VBG 4) must
be observed.
• The local regulations for the installation of electrical systems and accident prevention regulations must be observed.
• The electrical installation must be carried out in accordance with relevant regulations (e.g. observe conductor cross
sections, fuses, earth connections).
• If personal and fire protection is required when using the frequency converter, all-current sensitive fault current
protection switches (residual current devices of type B) must be used (in accordance with DIN VDE 0160 and EN 50178).
These oer reliable protection for the high frequency alternating currents occurring during FC operation and smooth
and pulsating direct fault currents. Common fault current protection switches of type A are not approved.
• Only use permanently wired mains connections.
• Earth the frequency converter in accordance with DIN EN 61140; VDE 0140-1.
• Contact currents > 3.5 mA may occur in the VAU. In this case an additional protective earth conductor
with the same cross section as the original earth conductor must be installed in accordance with DIN EN
61800-5-1. Whether the equipment concerned must be additionally earthed can be determined from
the respective equipment instructions. A second protective earth conductor can be connected on the
outside of the device below the control cable feed. A suitable M4x10 screw (2.0 Nm torque) is included
in the scope of delivery.
• When using dierent voltage levels (e.g. +24V/ 230 V) crossing cables must always be avoided! The user must also
ensure that the applicable regulations are complied with (e.g. double or reinforced insulation in accordance with DIN
EN 61800-5-1)!
• The circuit boards contain highly sensitive MOS semiconductor elements which are particularly sensitive to static
electricity. Please avoid, therefore, touching the strip conductors or components with your hands or with metal objects.
When connecting the conductors, only the screws of the terminal strips may be touched with insulated screwdrivers.
i
• In a residential environment this product may cause high frequency interference necessitating interference suppression
measures!
• Information on the EMC-compliant installation, such as shielding, earthing and cable routing, can be found in the
documentation of the frequency converters. This information must also be always observed for frequency converters
bearing the CE mark. Adherence to the limits required by EMC legislation is the responsibility of the manufacturer of the
plant or machine.
1.4 OPERATING INFORMATION
DANGER
Mortal danger from electric shock!
Death or serious injury!
2 mim
Due to charged capacitors the device might still carry dangerous voltage for up to 2 minutes after disconnection from
the mains.
Touching exposed or open terminals, conductors and device components can lead to serious injury or death!
Therefore, opening the device or removing the covers or control panel is only permitted 2 minutes after the device
has been switched to zero potential.
Even with the motor at rest (e.g. on account of an electronic lock, blocked drive or short circuited output terminal) the
mains connection terminals, motor terminals and terminals for the brake resistance may still carry dangerous voltage.
A shut down motor does not equate to an electrical separation from the mains.

BECKERVAU 1.1/1AC 5
DANGER
Mortal danger from rotating mechanical components!
Death or serious injury!
Under certain configurations the converter might automatically start after activation of the mains.
Systems with frequency converters installed might need to be equipped with additional protective devices in accordance with the
respective applicable safety regulations (e.g. laws on technical equipment, accident prevention regulations etc.).
If the required covers are removed without authorisation or with incorrect use, installation or operation there is a risk of serious
personal injury or property damage.
All covers must be kept closed during operation.
i
IMPORTANT INFORMATION
Please note the following information during operation:
• The frequency converter operates with high voltages.
• When operating electrical equipment, some components of this equipment inevitably carry dangerous voltages.
• The emergency stop facilities according to DIN EN 60204-1; VDE 0113-1:2007-06 must remain operational during all
operating modes of the control device. Resetting the emergency stop facility must not lead to uncontrolled or undefined
reactivation.
• To ensure safe disconnection from the mains the mains supply cable to the frequency converter must be disconnected
synchronously and at all poles.
• A pause of 1 to 2 min. must be adhered to between successive mains connections.
• Certain parameter settings may cause the frequency converter to automatically restart after a supply voltage failure.
• For a sound motor overload protection the motor parameters, in particular the I2t settings, must be configured correctly.
• The frequency converter does not provide internal motor overload protection. Motor overload protection can also
be ensured using an external PCT/bimetallic switch.
• The frequency converter must not be used as an „emergency stop facility“ (see DIN EN 60204-1; VDE 0113-1:2007-06).
• If the air is dusty, the cooling surfaces must be regularly cleaned.
