8. We recommend the
additional Cu strap
(1410..579.0) between
the mains lter and the
rst component in the
row to improve the EMC
properties. See Figure 4.2.
Figure 4.4 Protective earth conductor connection on the ServoOne CM system
CAUTION! Risk of injury due to incorrect wiring!
Carelessness may result in injuries.
The protective earth conductor connection is a safety feature. Therefore, make sure that all
connections have good contact and are sufciently secure that they cannot come loose.
4.4 Protective earth conductor connection
Step Action Comment
1.
Each device in the axis group must be earthed!
x Connect together the PE connections on the supply unit,
the axis controllers and the controller in series. Make
a connection from one of the devices to the PE rail (main
earth) in the switch cabinet
x (see) Figure 4.4
2.
Connect the protective earth conductor connections on all other
components, such as mains lter*), mains choke*) etc. in a star
topology to the PE rail (main earth) in the switch cabinet.
*) Components are only required
for the SO CM-P supply unit.
3.
Please take into account the local and national regulations and
conditions. The minimum cross-section of the protective earth
conductor must comply with the local safety requirements for
protective earth conductors in equipment with high leakage
current.
4.4.1 PE connection according to DIN EN 61800-5-1
The leakage current is > 3.5 mA. This situation results in the following minimum
requirements for the protective earth conductor cross-section as a function of the phase
conductor cross-section, as per EN61800-5-1.
