Warnings
WARNING
Be sure to ground the unit following the instructions in this manual.
Ungrounded units may cause electric shock and/or fire.
WARNING
This equipment should be installed, adjusted, and serviced by
qualified electrical maintenance personnel familiar with the
construction and operation of this type of equipment and the
hazards involved. Failure to observe this precaution could result in
death or severe injury.
WARNING
Components within the VSD Series power unit are live when the
drive is connected to power. Contact with this voltage is extremely
dangerous and may cause death or severe injury.
WARNING
Line terminals (L1, L2, L3), motor terminals (U, V, W) and the DC-
link/brake resistor terminals (-/+) are live when the drive is
connected to power, even if the motor is not running. Contact with
this voltage is extremely dangerous and may cause death or severe
injury.
WARNING
Even though the control I/O-terminals are isolated from line
voltage, the relay outputs and other I/O-terminals may have
dangerous voltage present even when the drive is disconnected
from power. Contact with this voltage is extremely dangerous and
may cause death or severe injury.
WARNING
The VSD Series drive has a large capacitive leakage current during
operation, which can cause enclosure parts to be above ground
potential. Proper grounding, as described in this manual, is
required. Failure to observe this precaution could result in death or
severe injury.
WARNING
Before applying power to the VSD Series drive, make sure that the
front and cable covers are closed and fastened to prevent exposure
to potential electrical fault conditions. Failure to observe this
precaution could result in death or severe injury.
