Safety Instructions

Safety Instructions
Terms according to DIN EN 61800
Before initial operation, make sure that the machine will not expose danger (e.g. run-
away moves). The conformity with the safety standards DIN EN 60204-1 and DIN EN
61800-5-1 must be ensured.
The manufacturer of the system or the machine has to meet the requirements of the
legal values regarding the Electromagnetic Compatibility (EMC). SIEB & MEYER units
can be operated in industrial areas, provided that the attached EMC information has
been taken into consideration.
SIEB & MEYER tests all products in its own EMC laboratory to ensure that the products
meet the respective standards, when they are installed properly.
Installation of the device differing from the product documentation and the manual "EMC
Guidelines" means that the machine manufacturer has to carry out new measurements
to comply with the regulations.
SIEB & MEYER devices meet the requirements of the Low-Voltage Directive 2014/35/
EU. The harmonized standards of DIN EN 50178 and DIN EN 60204-1 in combination
with the standards DIN EN 60947 and DIN EN 61800-5-1 are applied consequently.
Technical data and the connection specification can be found in the respective product
documents.
Line filters
If adequate interference suppression measures are applied and the appropriate use in
industrial applications of the device is ensured SIEB & MEYER devices comply with the
Directive EMC Directive 2014/30/EU in terms of the EMC Product Standard (PDS) DIN
EN 61800-3.
The use of line filters helps reaching the following:
▶Resistance to interference. The electronic system is protected against high-fre-
quency disturbances, possibly infiltrated via the mains cable.
▶Protection against radiation. High-frequency disturbances are reduced to legally
authorized measure. This prevents effects of the transients to adjacent components
or devices.
▶Products, not equipped with an integrated AC supply line filter must be operated
with an upstream line filter.
▶Using SIEB & MEYER devices in residential or business areas as well in small busi-
nesses requires additional interference suppression.
For detailed information refer to the manual "EMC Guidelines", chapter "EMC Prod-
uct Standard DIN EN 61800-3 for PDS".
Note
Refer to the product documentation of your device to find out whether or not your device
is equipped with a line filter. For detailed information on line filters refer to the manual
"EMC Guidelines".
3.4 Reasonably Foreseeable Misuse
The Machinery Directive defines a "reasonably foreseeable misuse" as "use of machin-
ery in a way not intended in the instructions but which may result from predictable hu-
man behavior".
SIEB & MEYER products are no products according to the EU Machinery Directive.
During design and construction of the machine as well as in the operation manual the
machine manufacturer is obliged to give consideration to the intended (appropriate) use
of the machine and risks arising from reasonably foreseeable misuse of the machine.
10 Drive Amplifier SD4B - Hardware Description

To avoid injuries and material damage any use, installation and setup of SIEB & MEYER
products by non-experts which exceed the technical data specified in the product docu-
mentation (high voltages, temperatures etc.) is considered to be not intended use and
forbidden.
Adhere to the safety instructions on the device and in the product documentation.
3.5 Electrical Connection
DANGER
Risk of serious injuries due to touch voltages
After electric devices have been switched off touch voltages may occur de-
pending on the device up to 4 minutes. Longer construction-related dis-
charge times are possible. Refer to the product documentation of your de-
vice.
→ All work at and within the units must only be carried out, when the
units are turned off, the mains supply is cut and the DC bus is com-
pletely discharged.
→ Never touch energized parts after a device has been switched. off.
→ Consider the VDE regulations and the applicable accident prevention
regulations (e.g. VBG 1 and VBG 4).
DANGER
Risk of serious injuries due to improper connection to earth
Incorrect or insufficient connection of the system to earth may cause dan-
gerous currents.
→ Connection to earth must be realized according to the instructions in
the product documentation of your device.
The electrical installation must be carried out according to the relevant electrical codes
(e.g. appropriate wire gauges, fuse protection and connections of ground conductors
must be considered).
Note
SIEB & MEYERdevices are conceived for connection to symmetrically grounded TN
networks. For detailed information regading the connection to TN networks or other net-
works refer to the manual "EMC Guidelines", chapter "Connection to Different Supply
System Types".
Recommendations for the installation complying EMC (e.g. shields, connection to earth
and line installations) can be found in the technical manuals of your device (only for ma-
chine manufacturers). The manufacturer of the system or machine has to meet the re-
quirements of the legislation regarding the EMC.
11Drive Amplifier SD4B - Hardware Description
Safety Instructions

Safety Instructions
1. Consider that the mains supply must be protected via an overload release with re-
stricted guidance for each mains phase. The mains line should not be switched on,
before the work is completed.
2. Before turning on the unit the first time, make sure that the connected machine will
not have runaway axes.
3. Never connect capacitive loads to the output phases of the servo amplifiers and fre-
quency converters.
4. Prevent cable loops. Therefore, the units must only be connected to earth at the
provided PE connection for the mains supply line and the racks only at the provided
earth screw.
DANGER
Hazardous voltage
The use of filters causes leakage currents on the protective earth conduc-
tor (PE) which in the event of an error may be considerably higher than the
rated values. To protect persons against dangerous voltages filters must be
connected to earth before they are taken into operation. Possibly a resid-
ual current device cannot be used. According to DIN EN 61800-5-1/ DIN
EN 60204-1 the following measures are required when leakage currents
≥3.5 mA occur:
→ Install a connection without connector on the device and attach a cor-
responding warning note on the device. which also must appear in the
documentation of the device.
→ Use a protective conductor with min. conductor cross-section of
10 mm² or
→ install a second protective conductor: connect it in parallel to the first
protective conductor by using separate terminals.
Operation with residual current device (RCD)
Note
For detailed information regarding the operation with residual current device (RCD) re-
fer to the manual "EMC Guidelines", chapter "Safety-relevant Aspects, Residual Current
Device (RCD)". Also consider the standard DIN EN 60204-1, section 8: additional re-
quirements for electrical equipment with earth leakage currents greater than 10 mA.

The maximum storage period is 2 years. Electrolytic capacitors produce high leakage
currents when a voltage is applied after a long storage period without applied voltage
and must be reformed. For this purpose, the operating voltage is applied via a 1 kΩ se-
ries resistor for one hour. Please contact the SIEB & MEYER service department for de-
tails.
