Earthing Procedure

Screw the enclosure of the digital servo amplifier JetMove 206B-230 onto
a highly conducting, earthed panel.
Do only use the servo amplifier JetMove 206B-230 at the three-phase,
earthed industrial network (TN network, TT network with earthed neutral,
5,000 A max, symmetric rated current at 400 / 480 V + 10 %).
The servo amplifier must not be operated when connected to unearthed
networks and to unsymmetrically earthed networks.
A one-phase connection to these mains can be established by means of a
mains phase and a neutral wire.
The three-phase connection may only be established by means of an
isolating or autotransformer (also refer to chapter "Power supply
connection", page 37, and chapter 10 "Connection Diagrams", page 79).
The leakage current of the digital servo amplifier JetMove 206B-230
is greater than 3.5 mA. Therefore, a second protective earth
conductor is required in order to avoid electric shocks.
For this, the following measures have to be taken:
• The protective earth conductor must be connected to the PE screw (1)
located at the top side of the rack as well as to the PE terminal X1 (2);
for this, please refer to Fig. 1.
The cross-sectional areas of the two earthing conductors must be equal
to the cross-sectional areas of the supply lines (1.5 mm
• A durable connection with the power supply of the digital servo amplifier
JetMove 206B-230 has to be provided.
• Correct cabling of the PE bus according to the connection diagram must
be carried out, chapter 10 "Connection Diagrams", page 79.
