• Make sure that the voltage between the
drive output terminals (T1/U, T2/V, T3/W)
and the grounding (PE) busbar is close to
0 V.
• Make sure that the voltage between the
drive input power terminals (L1, L2, L3)
and the grounding (PE) busbar is close to
0 V.
• Make sure that the voltage between the
drive DC terminals (UDC+, UDC-) and
the grounding (PE) terminal is close to
0 V.
• Install temporary grounding to the drive
output terminals (T1/U, T2/V, T3/W).
Connect the output terminals together as
well as to the PE.
Start-up and operation:
• Make sure that the operator cannot run the
motor over the rated speed. Motor
overspeed causes overvoltage that can
damage or destroy the capacitors in the
intermediate circuit of the drive.
General safety in operation
These instructions are for all personnel that
operate the drive.
WARNING! Obey these instructions. If
you ignore them, injury or death, or
damage to the equipment can occur.
• Do not control the motor with the line side
disconnect at the drive power supply;
instead, use the control panel start and stop
keys or commands through the I/O terminals
of the drive.
• Give a stop command to the drive before
you reset a fault. If you have an external
source for the start command and the start is
on, the drive will start immediately after the
fault reset, unless you configure the drive for
pulse start. See the firmware manual.
• Before you activate automatic fault reset
functions of the drive control program, make
sure that no dangerous situations can occur.
