Printed circuit boards
Safe start-up and operation

General safety
These warnings are intended for all who plan the operation of the drive or operate the
drive.
WARNING! Ignoring the following instructions can cause equipment malfunction
and damage to the fiber optic cables:
•
Handle the fiber optic cables with care. When unplugging optic cables, always grab
the connector, not the cable itself. Do not touch the ends of the fibers with bare hands
as the fiber is extremely sensitive to dirt. The minimum allowed bend radius is 35 mm
(1.4 in.).
WARNING! Ignoring the following instructions can cause damage to the printed
circuit boards:
•
The printed circuit boards contain components sensitive to electrostatic discharge.
Wear a grounding wrist band when handling the boards. Do not touch the boards
unnecessarily.
WARNING! Ignoring the following instructions can cause physical injury or
death, or damage to the equipment:
•
Before adjusting the drive and putting it into service, make sure that the motor and all
driven equipment are suitable for operation throughout the speed range provided by
the drive. The drive can be adjusted to operate the motor at speeds above and below
the speed provided by connecting the motor directly to the power line.
•
Do not activate any automatic fault reset functions of the drive control program if
dangerous situations can occur. When activated, these functions will reset the drive
and resume operation after a fault.
•
Do not control the motor with an AC contactor or disconnecting device
(disconnecting means); instead, use the control panel keys
and , or
commands via the I/O board of the drive. The maximum allowed number of charging
cycles of the DC capacitors ie, power-ups by applying power, is five in ten minutes.
Note:
•
If an external source for start command is selected and it is ON, the drive will start
immediately after an input voltage break or fault reset unless the drive is configured
for 3-wire (a pulse) start/stop.
•
When the control location is not set to local, the stop key on the control panel will not
stop the drive.
