2.6 Electrical Installation

For connector overview (➜ # 156). For more interface pinout refer to the Instructions
Manual.

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.
There is a danger of serious personal injury or death by electrical shock or electrical arcing.
Capacitors can still have dangerous voltages present up to 5 minutes after switching off the
supply power. Control and power connections can still be live, even if the motor is not rotat-
ing.
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 warn-
ing signs).
Never remove electrical connections to the drive while it is live.
Wait at least 5 minutes after disconnecting the drive from the main supply power before
touching potentially live sections of the equipment (e.g. contacts) or undoing any con-
nections.
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 (➜ # 156).
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).
Excessively high external fusing will endanger cables and devices. The fusing of the voltage
supply must be installed by the user, best values (➜ # 49). 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 off circuit of the installation.
The emergency off circuit must operate the supply contactor.
DANGER
High Voltage up to 900 V!
