JetMove 203-230
1.2.3
Jetter AG
Earthing procedure
Screw the enclosure of the digital servo amplifier JetMove 203-230 onto a
highly conducting, earthed panel.
Do only use the servo amplifier JetMove 203-230 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.
One-phase connection to this power supply is only possible via one mains
phase and the neutral conductor.
Der drei-phasige Anschluss darf nur über einen Tenn- oder
Spartransformator vorgenommen werden, (siehe auch chapter
"Connection type of the voltage supply", page 35 und chapter 10 "Wiring
Diagrams", page 71).
The digital servo amplifier JetMove 203-230 has got a leakage current
greater than 3.5 mA. In order to avoid electric shocks, a second
protective earth conductor will be required.
For this, the following measures must be taken:
•
The PE must be connected to the bolt (1) located at the top side of the
rack, as well as to the PE terminal X1 (2); for this, please refer to 1.
The cross-sectional area of the two earthing conductors must be equal
to the cross-sectional area of the supply lines (1.5 mm
•
A durable connection with the power supply of the digital servo amplifier
JetMove 203-230 must be provided.
•
Correct cabling of the PE bus according to the connection diagram (cf.
chapter 10 "Wiring Diagrams", page 71) must be carried out.
