CAUTION!
The user must wear noise protection and hearing protection.

The A-weighted sound pressure level LpA is 84 to 87 dB.
The A-weighted sound power level LWA is 99 to 103 dB.

INFORMATION

This numerical value was measured on a new machine under the operating conditions specified
by the manufacturer. The noise behaviour of the machine might change depending on the age
and wear of the machine.

Furthermore, the noise emission also depends on production engineering factors, e.g. speed,
material and clamping conditions.

INFORMATION

The following factors influence the actual degree of the noise exposure of the operator:

 Characteristics of the working area, e.g. size or damping behaviour,
 other noise sources, e.g. the number of machines,
 other processes taking place in proximity and the period of time, during which the operator

is exposed to the noise.
Furthermore, it is possible that the admissible exposure level might be different from country to

country due to national regulations.

3.9 Electrical connection

WARNING!
Danger to life caused by high leakage currents for an interrupted protective conductor.

The drive components conduct a high leakage current via the protective conductor.
Touching conductive parts when the protective conductor is interrupted can result in
death or serious injury.

 Observe the following notes on the connection for machines with frequency converters.

To ensure trouble free operation we recommend the mains supply impedance is less than 1% .
The mains supply impedance is the alternating current resistance in the public supply network.
If the input impedance to the inverter does not coincide with the impedance of the line, reflec
tions occur, which reduces the power transmission and can lead to a non-linear frequency
response.

WARNING!
The three-phase electrical connection may only be performed by an electrician or under

the guidance and supervision of an electrician.
CAUTION!

Arrange the machine's connection cable in such a way that it will not cause a tripping

0.0.1 Regulated drives in connection with residual current devices

Speed-controlled drives are one of the standard equipment in machine and plant construction
and perform various tasks. Compared to a simple motor, the electronic rectifiers or converters
require some special features for the necessary safety measures for electrical safety. Depend
ing on the application, the use of a fault current protection device, differential current monitor­ing or insulation monitoring can make more sense.

For electrical safety, DIN VDE 0100-410 (VDE 0100 part 410): 1997-01 "Erection of heavy cur­rent installations up to 1000V" is a basic standard. It describes both, the admissible net forms
and the necessary protective measures against dangerous body currents. Based on this stand
ard DIN EN 50178 (VDE 0160): 1998-04 "Equipping of heavy current systems with electronic
equipment" specifies the protective measures to be applied to controlled drives in more detail. It
calls for: "In the case of electronic equipment, the protection of persons against dangerous
body currents must be carried out in such a way that a single fault does not cause any danger."

Regulated drives with residual current devices

The TN-S system is the most common network form for the operation of controlled drives. This
is done, among other things, for EMV reasons and to avoid vagabonding currents. In accord
ance with DIN VDE 0100-410 (VDE 0100-410): 1997-01, fault current protective devices
(ELCB) can be used as a protective measure against dangerous body currents. According to
DIN VDE 0100-482 (VDE 0100 part 482): 2003-06 "Electrical installations of buildings", cables
and wiring systems in fire-endangered plants must be protected by ELCBs with a rated differen
tial current of 300 mA. According to IEC 60755, ELCBs differ in the type of fault currents they
can detect. In conjunction with electronic devices currents with DC components may occur.

0.0.2 Protection from Dangerous Shock Currents, use of ELCBs

To achieve increased safety in all installation systems, and in power supply ranges for which
the installation provisions stipulate or recommend the ELCB devices.

Measure for “Protection from Dangerous Shock Currents”, as regulated in DIN VDE 0100 Part

410. All measures are to be mentioned:

 Protection from indirect contact – as protection against fault by shutting down in the event of

inadmissibly high contact voltage by short circuit shock on the operating resource.

 Protection from direct contact – as additional protection by shutting down in the event of

contact with a live conductor. Dangerous shock currents are shut down within the shortest
possible time, if the rated fault current of the circuit breaker is 30 mA, for a personal protec
tion system 10 mA.

 Fire prevention – Prevention of the origination of electrically-ignited fires if the rated fault

current of the circuit breaker is 300 mA. Operating premises at risk of fire to VdS 2033:
2002-02 300 mA.

0.0.3 Current in the protective earth conductor - Leakage current

With EMC filters in frequency converters, the leakage current is always greater than 3.5 mA
due to physics. Some types of frequency converters also achieve a leakage current of up to
300mA.

Therefore, a fixed earth connection is required and the minimum cross section of the protective
earthing conductor must conform to local safety regulations for devices with high leakage cur
rent. This is achieved by providing a permanent fixed earthing connection with two independ­ent conductors, each having a cross section the same as the power supply cord or greater.

Preferably, machines with frequency converters are therefore to be permanently connected to a
terminal box, otherwise an additional fixed earth connection is required, which is not routed
over the plug, and must correspond to at least the cross-section of the cable in the plug.

Since a direct current may be caused by the frequency converter in the protective earthing con­ductor, if an upstream residual current device (ELCB / RCD) is required in the network, the fol­lowing guidelines must be followed:

To avoid an operating fault, you need an AC/DC-sensitive ELCB. Be absolutely sure
which leakage current security is necessary for dangerous body currents, as regulated
in DIN VDE 0100 part 410, at your mains connection.

0.0.4 When the ELCB triggers

 Pulse current - sensitive ELCB type A

ELCB type A independent of rated voltage, for triggering when changing fault cur­rents and pulsing DC fault currents.

 AC/DC - sensitive ELCB type B

ELCBs of series type B also accept the detection of smooth AC fault cur­rents as well as the detection of fault current shapes of type A; they are
therefore suitable for all the circuits mentioned. ELCBs of this series therefore detect all
types of fault current according to the triggering characteristic B, i.e. both smooth DC fault
currents and also all AC fault currents of all frequencies and mixed frequencies up to 1 MHz
are detected and switched off reliably in the event of a fault.

 Alternating current - sensitive ELCBs of type AC (only alternating current) are

unsuitable for frequency converters. Alternating current - sensitive ELCBs of type

AC are not customarily used and are no longer permitted in Germany.
Type B must be used with 3-phase converters.
When using an external EMC filter, to avoid false error shutdowns, a time delay of at least 50

ms is required. The leakage current can exceed the threshold trigger value for an error shut
down if the phases are not switched on at the same time.

2.3 Examples to calculatory determine the required speed for your drilling machine

The necessary speed is depending on the diameter of the drill bit, on the material which is
being machined as well as on the cutting material of the drill bit.

Material which needs to be drilled: St37
Cutting material (drill bit): HSS spiral bit
Set point of the cutting speed [vc] according to the table: 40 meters per minute
Diameter [d] of your drill bit: 30 mm = 0,03 m [meters]
Selected infeed [f] according to the table: about 0.35 mm/rev

Speed

Set a speed on your drilling machine which is less than the determined speed.

INFORMATION

In order to facilitate the production of larger drill holes they need to be pre-drilled. This way, you
reduce the cutting forces and improve the guiding of the drill bit.

The pre-drilling diameter is depending on the length of the
chisel edge. The chisel edge does not cut, but it squeezes
the material. The chisel edge is positioned at an angle of
55° to the major cutting edge.

As a general rule of thumb it applies: The pre-drilling
diameter is depending on the length of the chisel edge.

Recommended working steps for a drilling diameter of 30 mm

Example:
1st working step: Pre-drilling with Ø 5 mm.
2nd working step: Pre-drilling with Ø 15 mm.
3rd working step: Drilling with Ø 30 mm.

4.6 Cooling lubricants and tanks

CAUTION!
The cooling lubricant can cause diseases. Avoid direct contact with cooling lubricant or

parts covered in cooling lubricant.

Cooling lubricant circuits and tanks for water-cooling lubricant mixtures must be completely
emptied, cleaned and disinfected as needed, but at least once per year or every time the cool
ing lubricant is replaced.

If fine chips and other foreign matters are accumulated in the coolant tank, the machine can no
longer be correctly supplied with coolant. Furthermore, the lifetime of the coolant pump is
reduced.

When processing cast iron or similar materials generating fine chips, cleaning the coolant tank
more often is recommended.

Limit values
The cooling lubricant must be replaced, the cooling lubricant circuit and tank emptied,

cleaned and disinfected if

 the pH value drops by more than 1 based on the value during initial filling. The maximum

permissible pH value during initial filing is 9.3

 there is a perceivable change in the appearance, odour, floating oil or increase of the bacte-

ria to more than 10/6/ml

 there is an increase in nitrite content to more than 20 ppm (mg/1) or nitrate content to more

than 50 ppm (mg/1)

 there is an increase in the N-nitrosodiethanolamine (NDELA) to more than 5 ppm (mg/a)

-

CAUTION!
Comply with the manufacturer's specifications for mixture ratios, hazardous substances,

e.g. system cleaners, including their permissible minimum use times.
CAUTION!

Since the cooling lubricant escapes under high pressure, pumping out the coolant by
using the existing cooling lubricant pump via a pressure hose into a suitable tank is not
recommended.

ENVIRONMENTAL PROTECTION
During work on the cooling lubricant equipment please make sure that

 collector tanks are used with sufficient capacity for the amount of liquid to be col-

lected.

 liquids and oils should not be spilled on the ground.

Clean up any spilled liquid or oils immediately using proper oil-absorption methods and dis­pose of them in accordance with current statutory environmental regulations.

Collect leakages

Do not re-introduce liquids spilled outside the system during repair or as a result of leakage
from the reserve tank, instead collect them in a collecting container for disposal.

Disposal

Never dump oil or other substances which are harmful to the environment into water inlets, riv­ers or channels. Used oils must be delivered to a collection centre. Consult your supervisor if
you do not know where the collection centre is.
