Important notes

High voltage up to 900V!
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 five minutes after switching off the supply power. Control and power
connections can still be live, even if the motor is not rotating.

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 cur-
rent of the units. Implement the wiring according to the connection diagram on p. 51.
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 circum-
stances (see IEC 60204-1).
Excessively high external fusing will endanger cables and devices. The fusing of the AC
supply input and 24V supply must be installed by the user, best values are given on p.27.
Hints for use of Residual-current circuit breakers (FI) ð p.44.
The servo amplifier's status must be monitored by the PLC to acknowledge critical situa-
tions. Wire the BTB/RTO contact in series into the emergency off circuit of the installation.
The emergency off circuit must operate the supply contactor.
It is permissible to use the setup software to alter the settings of the servo amplifier. Any
other alterations will invalidate the warranty.

WARNING
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
supply power before touching potentially live sections of the equip-
ment (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.
