2.6.1 Important Notes

Only professional staff who are qualified in electrical engineering are allowed to install the
drive. Wires with color green with one or more yellow stripes must not be used other than for
protective earth (PE) wiring.
WARNING
High Voltage up to 900 V!
There is a danger of electrical arcing with damage to contacts and serious
personal injury. Capacitors can still have dangerous voltages present up
to 5 minutes after switching off the supply power. Control and power con-
nections can still be live, even if the motor is not rotating.
Only install and wire the equipment when it is not live.
Make sure that the cabinet is safely disconnected (for instance, with a
lock-out and warning signs).
Never remove electrical connections to the drive while it is live.
Wait at least 5 minutes after disconnecting the drive from the main sup-
ply power before touching potentially live sections of the equipment
(e.g. contacts) or undoing any connections.
To be sure, measure the voltage in the DC bus link and wait until it has
fallen below 50 V.
Wrong mains voltage, unsuitable motor or wrong wiring will damage the amplifier. 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 (➜ # 178). 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 circumstances (see IEC 60204-1).
With SERVOSTAR 640/670 external mains chokes and mains filters are required.
Excessively high external fusing will endanger cables and devices. The fusing of the voltage
supply must be installed by the user, best values (➜ # 54). Hints for use of Residual-current
circuit breakers (FI) see Instructions Manual.
Route power and control cables separately. We recommend a distance of at least 200 mm. If
a motor power cable is used that includes cores for brake control, the brake control cores
must be separately shielded. Ground the shielding at both ends. Ground all shielding with
large areas (low impedance), with metalized connector housings or shield connection clamps
wherever possible.
Feedback lines may not be extended, since thereby the shielding would be interrupted and
the signal processing could be disturbed. Lines between servo amplifiers and filter or external
brake resistor must be shielded. Install all power cables with an adequate cross-section, as
per IEC 60204.
The servo amplifier's status must be monitored by the PLC to acknowledge critical situ-
ations. Wire the BTB/RTO contact in series into the emergency stop circuit of the install-
ation. The emergency stop circuit must operate the supply contactor.
