Connecting the supply voltages
The JM-3000 has got individual power supplies for the control unit and
for the power section. The control unit receives its 24V supply voltage via
the upper busbar (+24V DC and GND) from the switching power supply
integrated into the supply unit.
The power section of the servo amplifier receives its DC link supply also
from the supply unit via the lower busbar (DC Link+ and DC Link-).

First make sure that all JM-3000 servo amplifiers
are arranged in a row with of the JM-3000 supply
unit.
See installation instructions in chapter 2.1

Always connect the 24 V controller supply voltage
for the servo amplifiers first.
If you are using several servo amplifiers, all 24 V
DC and all GND connections must be connected.
To do this, use the pre-assembled rail elements
as shown in Fig. 3.9. To be able to rotate the rail
elements, the screws must be slightly open.

Only connect the DC link supply when you want to
put the servo amplifiers into operation.
If you are using several servo amplifiers, all DC
Link+ and DC Link- connections must be con-
nected.
Also use the pre-assembled rail elements ac-
cording to Fig. 3.10. To be able to rotate the rail
elements, the screws must be slightly open.

Once all rail elements are in place, the screws
must be tightened again!

Make sure that all connections have good contact and are screwed
tight with sufficient torque (2.1 Nm) so that they cannot come loose by
themselves. Jetter AG does not assume any liability for stable and safe
operation when using connecting elements that do not comply with the
specifications.
