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 EN60034 (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).

l
10 BA 13.0008 − EN 2.1
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 + 5%,
frequency + 2%, wave form, symmetry − leads to excessive temperatures and affects the
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.
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.

6. Operation
Vibration severities vrms £3.5 mm/s (Pr £15 kW) or 4.5mm/s (Pr > 15 kW) are acceptable in
coupled mode operation. In case of deviations from normal operation, e.g. increased
temperatures, noises, vibration, find the cause and, if necessary, contact the
manufacturer. Do not switch off the protection devices, not even for trial runs. Switch off
the machine in problematic situations.
If the drive is exposed to dirt, clean it regularly.
Regrease the bearings using the relubrication facility while the low−voltage machine is
running. Observe the saponification number. If the grease drain hole is sealed with a plug,
(IP54 drive end; IP23 drive and non−drive end), remove the plug before commissioning. Seal
the bore holes with grease. Replace the prelubricated bearings (2Z−bearings) after approx.
10,000 h (2pole) or 20,000 h (multi−pole), but no later than after three to four years or
according to the manufacturer’s instructions.

4.1 Transport, storage and installation
}Danger!
ƒUse appropriate means of transport or hoists:
– Ensure safe fixing.
ƒTransport the motors free of vibrations.
ƒAvoid heavy shocks.
Storage
ƒfree of vibration
if a certain risk of vibration exists, we recommend to rotate the rotor once per week
ƒdry, in a non−aggressive environment
ƒfree of dust
ƒfree of extreme temperature changes
Corrosion
ƒSteel parts are corrosion−protected when being delivered. Do not remove the
protection! Check it every three months and, if necessary, renew it.
Installation
The motors are tested for operation and are ready for use.
Preparations
ƒRemove the corrosion protection from the steel parts.
ƒCheck for transport damage and fix key, if necessary.
ƒThe mounting depends on the motor design, the weight and the motor torque.
ƒBefore mounting the motor, foot and flange surfaces must contact the mounting
surfaces evenly. Insufficient motor alignment reduces the service life of the bearings
and the transmission elements!
ƒClutches and other transmission elements must be mounted according to the
corresponding instructions. Avoid shocks onto the shafts and do not exceed the
permissible radial and axial forces to avoid damage to the bearings!
ƒProvide sufficient space for unimpeded ventilation.

5 Electrical installation
{Danger!
ƒElectrical connection must only be carried out by qualified personnel!
ƒConnections must only be made when the equipment is de−energised!
Danger through unintended starts or electric shocks.
(Stop!
It must be ensured that the supply voltage corresponds to the voltage
indicated on the nameplate.
Voltage supply
ƒInverter−optimised motors
– must be supplied by inverters.
– connect the encoders mounted to the motor with the corresponding connections
of the inverter.
ƒHolding brake (as option)
ƒFollow the Operating Instructions for the inverter used to connect it.
Cable cross−sections
ƒSelect appropriate connection cables to avoid impermissible heating (DIN
57100/VDE 0100 T523).
ƒWhen extremely long cables are used, we recommend to use the next cable cross
section up to reduce the power losses. Observe the minimum cross sections to DIN
VDE 0298−4.
ƒEstablish the electrical connection as shown in the circuit diagram attached to each
motor. The circuit diagrams for the standard designs can be found in chapter 5.2.2.
Motor protection
ƒThe motor cable cannot be protected by temperature monitorings or PTC thermistors
in the motor winding:
– Take measures to DIN 57100 / VDE 0530.
ƒThe inverter changes current and voltage such that the output current can be
considerably higher than the input current. The motor cable cannot be protected via
the mains input fuses of the inverter:
– Take measures to DIN 57100 / VDE 0530.
ƒEnsure careful earthing of the motor housing!
– If the motor is inverter driven, high−frequency voltages may be capacitively
transferred to the motor housing.
