2 Safety instructions
2.1 Personnel responsible for safety
Operator
ƒ An operator is any natural or legal person who uses the drive system or on behalf of
whom the drive system is used.
ƒ The operator or his safety officer must ensure
– that all relevant regulations, instructions and legislation are observed.
– that only qualified personnel work with and on the drive system.
– that the personnel have the Operating Instructions available for all corresponding
operations.
– that non−qualified personnel are prohibited from working with and on the drive
system.
Skilled personnel
Skilled personnel are persons who − because of their education, experience, instructions,
and knowledge about corresponding standards and regulations, rules for the prevention
of accidents, and operating conditions − are authorised by the person responsible for the
safety of the plant to perform the required actions and who are able to recognise potential
hazards.

Residual hazards
l Install a guard, if necessary.
High−frequency voltages can be capacitively transferred to the motor housing
through the inverter supply.
l Carefully earth the motor housing.
Danger of unintentional starting or electrical shocks
l Perform connection work only in the de−energised state, only with motor
in standstill.
l Built−in brakes are not fail−safe brakes.
l If necessary, limit the maximum current, perform a function block
interconnection with disconnection after a few seconds of operation with I

l The integrated overload protection does not prevent overload under all
conditions!
Built−in brakes are not fail−safe brakes .
l Speed reduction is possible.
Fuses are not a motor protection.
l Use current−dependent motor protection switches for average operating
frequency
l Use built−in thermal detectors at high operating frequency.
Excessive torques lead to a break of the motor shaft or demagnetisation
l Do not exceed the maximum torques according to the catalogue.
Lateral forces from the motor shaft are possible.
l Perfectly align shafts of motor and driving machine to each other.

2.3 Safety instructions for low−voltage machinery
in conformity with the Low−Voltage Directive 73/23/EEC
1. General
Low−voltage machines have dangerous, live and rotating parts as well as possibly hot
surfaces. All operations serving transport, connection, commissioning and maintenance
are to be carried out by skilled, responsible technical personnel (observe prEN 50110−1/
VDE 0105; IEC 364). Improper handling can cause severe injuries or material damage.
2. Application as directed
These low−voltage machines are intended for industrial and commercial installations.
They comply with the harmonised standards of the series EN60034 (VDE 0530). Their use
in hazardous areas is prohibited unless they are expressly intended for such use (follow
additional instructions).
The enclosures £ IP 23 are by no means intended for outdoor use. Air cooled designs are rated
for ambient temperatures between −20°C and +40°C and altitudes of £ 1000 m amsl. Check
indications on the nameplate and, if other observe them. The conditions on site must
correspond to all nameplate data.
Low−voltage machines are components for installation in machinery as defined in the
Machinery Directive 89/392/EEC. Commissioning is prohibited until conformity of the end
product with this Directive has been established (observe i.a. EN 60204−1).

3. Transport, storage
The forwarder must be informed directly after receipt of the goods about all damage or
deficiencies; if necessary, commissioning must be stopped. Tighten screwed−in ring bolts
before transport. They are designed for the weight of the low−voltage machine, do not
apply extra loads. If necessary, use suitable and adequately dimensioned means of
transport (e.g. rope guides).
Remove the shipping brace before commissioning. Reuse it for further transports. For
storage of low−voltage machines ensure a dry, dust−free and low−vibration (v rms
£O.2mm/s) environment (damage while being stored). Measure the insulation resistance
before commissioning. If the values are £1k per volt of rated voltage, dry the winding.
4. Installation
Ensure an even surface, solid foot or flange mounting and exact alignment if a direct clutch
is connected. Avoid resonances with a rotational frequency and double mains frequency
which may be caused during installation. Turn rotor by hand, listen for unusual slipping
noises. Check the direction of rotation when the clutch is not active (observe section 5).
Use appropriate tools to mount or remove belt pulleys and clutches (heat generation!) and
cover them with a touch guard. Avoid excessive belt tensions (technical list).
If required, provide pipe connections. Mounting positions with shaft end at top must be
protected with a cover which avoids the ingression of foreign particles into the fan. Free
circulation of the cooling air must be ensured. The exhaust air − also of other machines next
to the drive system− must not be intaken again immediately.
5. Electrical connection
All operations must only be carried out by qualified and skilled personnel when the
low−voltage machine is at standstill and when the machine is de−energised and protected
against unintentional restart. This also applies to auxiliary circuits (e.g. anti−condensation
heating).
Check safe isolation from the supply!
Exceeding of the tolerances specified in EN 60034−1 (VDE 0530, part 1) − voltage +
frequency +
electromagnetic compatibility. Observe the indications on the nameplate and the diagram
in the terminal box.
The connection must ensure a continuous and safe electrical supply (no loose wire ends);
use appropriate cable terminals. The connection to the PE conductor must be safe.
The clearance between shining, live parts and earth must not fall below: 8mm at Vr £550V,
10mm at Vr £725V, 14mm at Vr £1000V.
2%, wave form, symmetry − leads to excessive temperatures and affects the
5%,

No foreign objects, dirt or moisture in the terminal box. All unused cable entries and the
box itself must be sealed against dust and water. For the trial run without output
elements, lock the key. Check brake operation before commissioning of low−voltage
machines with brakes.
