SIEB & MEYER device are conceived for connection to TN mains. For
detailed information regading the connection to TN mains or other mains
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
machine manufacturers). The manufacturer of the system or machine has to meet the
requirements of the legislation regarding the EMC.
➮ Consider that the mains supply must be protected via an overload release with
restricted guidance for each mains phase. The mains line should only be
connected, when the work is completed.
➮ Before turning on the unit the first time, make sure that the connected machine will
not have runaway axes.
➮ Never connect capacitive loads to the output phases of the servo amplifiers and
frequency converters.
➮ 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
Connection of the power supply unit
This product may cause touch current in the protective earthing conductor. The
current in the protective earthing conductor can exceed 3.5 mA AC or 10 mA DC.
Pay attention to the local safety regulations for electric equipment with high
leakage currents, in particular the minimum cross-section of the protective earthing
conductor.
Operation with residual current device (RCD)
For detailed information regarding the operation with residual current device
(RCD) refer to the manual "EMC Guidelines", chapter "Safety-relevant
Aspects, Residual Current Device (RCD)".
3.8 Operation
