Safety Precautions
Before start-up, observe the warnings and safety instructions provided throughout this
manual.
WARNING
Internal components and circuit boards (except the isolated
I/O terminals) are at utility potential when the SVX9000/
SPX9000 is connected to the line. This voltage is extremely
dangerous and may cause death or severe injury if you
come in contact with it.
When the SVX9000/SPX9000 is connected to the utility, the
motor connections U (T1), V (T2), W (T3) and DC-bus/brake
resistor connections B–, B+ and R– are live even if the motor
is not running.
Do not make any connections when the AF drive is
connected to the utility line.
Do not open the cover of the AF drive immediately after
disconnecting power to the unit, because components
within the drive remain at a dangerous voltage potential for
some time. Wait at least five minutes after the cooling fan
has stopped and the keypad or cover indicators are dark
before opening the SVX9000/SPX9000 cover.
The control I/O terminals are isolated from the utility
potential, but relay outputs and other I/Os may have
dangerous external voltages connected even if power is
disconnected from the SVX9000/SPX9000.
Before connecting to the utility, make sure that the cover of
the drive is closed.
