Never disconnect the electrical connections to the servo amplifier while it is live.
In unfavorable circumstances this could cause destruction of the electronics.
Residual charges in the capacitors can have dangerous levels up to 300 seconds
after switching off the electrical supply. Measure the bus voltage on the DC bus
link (+DC/-DC) and wait until the voltage has fallen below 40V.
Control and power connections can still be live, even if the motor is not rotating.

SERVOSTAR
300 Installation Manual
Protect the servo amplifier from impermissible stresses. In particular, do not let any
components become bent or any insulation distances altered during transport and
handling. Avoid contact with electronic components and contacts.
Check the combination of servo amplifier and motor. Compare the rated voltage and
current of the units. Implement the wiring according to the connection diagram on
page 31.
Make sure that the maximum permissible rated voltage at the terminals L1, L2, L3 or
+DC, –DC is not exceeded by more than 10% even in the most unfavorable circums-
tances (see EN 60204-1 Section 4.3.1). An excessive voltage on these terminals can
lead to destruction of the regen circuit and the servo amplifier.
The fusing of the AC supply input and 24V supply must be installed by the
user (ð p.20).
Take care that the servo amplifier and motor are properly grounded.
Do not use painted (i.e. non-conductive) mounting plates.
Route power and control cables separately. We recommend a distance of at least
200mm. This improves the interference immunity required by EMC regulations.
If a motor power cable is used that includes cores for brake control, the brake con-
trol cores must be separately shielded.
Ground the shielding at both ends (ð p.32).
Ground all shielding with large areas (low impedance), with metalized connector hou-
sings or shield connection clamps wherever possible. Notes on connection techni-
ques can be found on page 34.
Feedback lines may not be extended, since thereby the shielding would be interrup-
ted and the signal processing could be disturbed.
Lines between amplifiers and external regen resistor must be shielded.
Install all power cables with an adequate cross-section, as per EN 60204 (ð p.21)
and use the requested cable material (ð p. 35) to reach max. cable length.
Wire the BTB/RTO contact in series into the safety circuit of the installation. The sa-
fety circuit must operate the supply contactor. This is the only way to ensure monito-
ring of the servo amplifier.
Ensure that there is an adequate flow of cool, filtered air into the bottom of the control
cabinet, or use a heat exchanger. Please refer to page 21.
It is permissible to use the setup software to alter the settings of the servo amplifier.
Any other alterations will invalidate the warranty.
