Operation
WARNING
The inverter operates at high voltages. When operating electrical devices, it is impossible to
avoid applying hazardous voltages to certain parts of the equipment.
The power supply and motor terminals - and if available the DC terminals - can carry
dangerous voltages even if the inverter is inoperative. Wait five minutes to allow the unit to
discharge after switching off the line supply before carrying out any installation work.
Emergency Stop facilities according to EN 60204, IEC 204 (VDE 0113) must remain
operative in all operating modes of the control equipment. Any disengagement of the
Emergency Stop facility must not lead to an uncontrolled or an undefined restart of the
equipment.
Wherever faults occurring in the control equipment can lead to substantial material damage
or even grievous bodily injury (that is, potentially dangerous faults), additional external
precautions must be taken or facilities provided to ensure or enforce safe operation, even
when a fault occurs (e.g. independent limit switches, mechanical interlocks, etc.).
Certain parameter settings may cause the inverter to restart automatically after an input
power failure, for example, the automatic restart function.
Motor parameters must be accurately configured for motor overload protection to operate
correctly.
This equipment is suitable for use in a power system up to 10,000 symmetrical amperes
(rms), for the maximum rated voltage + 10 % when protected by an appropriate standard
fuse (refer to the catalogue for the type of fuse).
The Power Modules are components with a high leakage current!
Use of mobile radio device (e.g. telephones, walky-talkies) with a transmission power > 1 W
in the immediate vicinity of the devices (< 1.5 m) can interfere with the functioning of the
equipment!
CAUTION
The line filter conducts a high leakage current via the PE conductor. Due to the high
leakage current a permanent PE connection for the line filter is required.
Furthermore, the following measures must be taken in accordance with EN 61800-5-1:
Either protective ground conductor cross-sections ≥ 10 mm
2
(8 AWG) Cu or installation of a
second protective ground conductor with both having the same cross-section as the line
input cable.
