1.4
The digital servo amplifier JetMove 203-230 is intended for use in industrial
surroundings. It can cause radio interferences in residential areas. It is operated at
the operator's own risk.
The noise immunity of a system corresponds to the weakest component of the
system. For this reason, correct wiring and shielding of the cables is important.

Instructions on EMI
Important!
Measures for increasing immunity to interfering in electric plants:
Earth the device adequately according to chapter 1.2.3 "Earthing
procedure", page 13.
Connect all grounding terminals of the JetMove 203-230. A double
grounding terminal will be needed!
– Connect the protective earth terminal located on the enclosure
– Connect the protective earth (PE) conductor to terminal X1.
see Fig. 1 on page 14
Connect the motor lines. An optional mains filter must be as close to the
servo amplifier as possible. Both sides of the cable must be shielded.
If a motor power cable is used which includes cores for brake control, the
brake control cores must be separately shielded. Earth the shielding at
both ends. The shielding braid must be placed on both ends of the
applicable cables.
The distance between the optional line filters and the servo amplifier
JetMove 203-230 must be kept as short as possible.
Please follow the instructions given in Application Note 016 "EMC-
Compatible Installation of the Electric Cabinet" published by Jetter AG.
The following instructions are excerpts from Application Note 016:
Screw the enclosure of the digital servo amplifier JetMove 203-230 onto a
highly conducting, earthed panel.
On principle, physical separation should be maintained between signal
and power lines. We recommend spacings greater than 20 cm. Cables and
lines should cross each other at an angle of 90°.
