2.7 Electrical Connection
DANGER
Risk of serious injuries due to touch voltages
After electric devices have been switched off touch voltages may occur depending
on the device up to 4 minutes. Longer construction-related discharge times are
possible. Refer to the product documentation of your device.
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 completely discharged.
Never touch energized parts after a device has been switched. off.
Consider the applicable VDE regulations and 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 dangerous
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).
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.
