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.
(See IEC 364, definition of skilled personnel)

2.2 Residual hazards

Protection of persons

ƒ The motor surfaces can become very hot. Danger of burns when touching!

– If necessary, provide protection against contact.

ƒ If the motor is inverter driven, high−frequency voltages may be capacitively

transferred to the motor housing.
– Ensure careful earthing of motor housing.

ƒ Danger through unintended starts or electric shocks

– Connections must only be made when the equipment is deenergised and the

motor is at standstill.

– Built−in brakes are not fail−safe brakes .

Device protection

ƒ Integrated temperature sensors do not provide full protection for the machine.

– If necessary, limit the maximum current, ensure a function block interconnection

with disconnection after a few seconds of operation with I > I
danger of blocking exists.

– Integrated overload protection does not protect against overloading under all

conditions.

ƒ Built−in brakes are not fail−safe brakes

– Torque can be reduced.

ƒ Fuses do not protect the motor.

– Use current−dependent motor protection switches for average switching

frequency.

– Use integrated temperature sensors for high switching frequency.

ƒ Excessive torques may lead to demagnetisation or a breakage of the motor shaft.

– Never exceed the maximum torques specified in the catalogue.

2.3 Safety instructions for low−voltage machines

in compliance with Low−Voltage Directive 73/23/EEC

General

Low−voltage machines have hazardous live and rotating parts and possibly also hot
surfaces.

Synchronous machines induce voltages at open terminals during operation.

All operations concerning transport, connections, commissioning and maintenance must
be carried out by qualified, skilled personnel (EN 50110−1 (VDE 0105−100) and IEC 60364
must be observed). Inappropriate use creates the risk of severe injury to persons and
damage to material assets.

BA 13.0009 − EN 2.1

Low−voltage machines may only be operated under the conditions that are indicated in the
section "Application as directed".

The conditions at the place of installation must comply with the data given on the
nameplate and in the documentation.

harmonised standards of the series EN60034 (VDE 0530). Their use in potentially
explosive atmospheres is prohibited unless they are expressly intended for such use
(follow additional instructions).

Low−voltage machines are components for installation into machines as defined in the
Machinery Directive 98/37/EC. Commissioning is prohibited until the conformity of the
end product with this directive has been established (follow i. a. EN 60204−1).

Low−voltage machines with IP23 protection or less are only intended for outdoor use when
applying special protective features.

The integrated brakes must not be used as safety brakes. It cannot be ruled out that factors
which cannot be influenced, such as oil ingress due to a defective A−side shaft seal, cause
a brake torque reduction.

Transport, storage

Damage must be reported immediately to the forwarder upon receipt; if required,
commissioning must be excluded. Tighten screwed−in ring bolts before transport. They are
designed for the weight of the low−voltage machines, do not apply extra loads. If
necessary, use suitable and adequately dimensioned means of transport (e. g. rope
guides).

Remove transport locking devices before commissioning. Reuse them for further
transport. When storing low−voltage machines, ensure a dry, dust−free and low−vibration
(v

£ 0.2 mm/s) environment (bearing damage while being stored).

Installation

Ensure an even surface, solid foot/flange mounting and exact alignment if a direct clutch
is connected. Avoid resonances with the rotational frequency and double mains frequency
which may be caused by the assembly. Turn rotor by hand, listen for unusual slipping
noises. Check the direction of rotation when the clutch is not active (observe section
"Electrical connection").

Use appropriate means to mount or remove belt pulleys and clutches (heating) and cover
them with a touch guard. Avoid impermissible belt tensions.

The machines are half−key balanced. The clutch must be half−key balanced, too. The visible
jutting out part of the key must be removed.

If required, provide pipe connections. Designs with shaft end at bottom must be protected
with a cover which prevents the ingress of foreign particles into the fan. Free circulation of
the cooling air must be ensured. The exhaust air − also the exhaust air of other machines
next to the drive system − must not be taken in immediately.

Safety instructions

Safety instructions for low−voltage machines

Electrical connection

All operations must only be carried out by qualified and skilled personnel on the
low−voltage machine at standstill and deenergised and provided with a safe guard to
prevent an unintentional restart.This also applies to auxiliary circuits (e. g. brake, encoder,
blower).

Check safe isolation from supply!

If the tolerances specified in EN 60034−1; IEC 34 (VDE 0530−1) − voltage ±5 %, frequency
±2 %, waveform, symmetry − are exceeded, more heat will be generated and the
electromagnetic compatibility will be affected.

Observe the data on the nameplate, operating notes, and the connection 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
plug−in connectors must be bolted tightly (to stop).

The clearances between blank, live parts and to earth must not fall below 8 mm at
U

£ 550 V, 10 mm at Ur £ 725 V, 14 mm at Ur £ 1000 V.

The terminal box must be free of foreign particles, dirt and moisture. All unused cable
entries and the box itself must be sealed against dust and water.

Commissioning and operation

Before commissioning after longer storage periods, measure insulation resistance. In the
case of values £ 1 kW per volt of rated voltage, dry winding.

For trial run without output elements, lock the featherkey. Do not deactivate the
protective devices, not even in a trial run.

Check the correct operation of the brake before commissioning low−voltage machines
with brakes.

Integrated thermal detectors do not provide full protection for the machine. If necessary,
limit the maximum current. Parameterise the controller so that the motor will be switched
off with I > I

Vibrational severities v
the clutch is activated.

If deviations from normal operation occur, e.g. increased temperatures, noises, vibrations,
find the cause and, if required, contact the manufacturer. In case of doubt, switch off the
low−voltage machine.

If the machine is exposed to dirt, clean the air paths regularly.

Shaft sealing rings and roller bearings have a limited service life.

Regrease bearings with relubricating devices while the low−voltage machine is running.
Only use the grease recommended by the manufacturer. If the grease drain holes are
sealed with a plug, (IP54 drive end; IP23 drive and non−drive end), remove plug before
commissioning. Seal bore holes with grease. Replace prelubricated bearings (2Z bearing)
after approx. 10,000 h − 20,000 h, at the latest however after 3 − 4 years.

The product−specific safety and application notes given in these instructions must be

Protection of the motor against impermissible voltage peaks

ƒ During operation of the motors on the frequency inverter or during switching

operations on the mains, voltage peaks that may damage the motor isolation can
occur.

ƒ In order to avoid malfunctions, the limit values specified in the table may not be

exceeded:
