Chapter 6 — Start-Up
Safety Precautions
Before start-up, note the following directions and warnings:
WARNING
Internal components and circuit boards of the drive are live
when the drive is connected to mains potential. Coming
into contact with this voltage is extremely dangerous and
may cause death or severe injury.
The motor terminals U, V, W and the DC-link/brake resistor
terminals B+/R+, R- are live when the drive is connected to
mains, even if the motor is not running.
The control I/O-terminals are isolated from the mains
potential. However, the relay outputs and other I/O-
terminals may have a dangerous control voltage present
even when the drive is disconnected from mains.
Do not make any connections when the drive is connected
to the mains.
After having disconnected the drive, wait until the
indicators on the keypad go out (if no keypad is attached
see the indicator through the keypad base). Wait 5 more
minutes before doing any work on drive connections. Do
not even open the cover before this time has expired.
Before connecting the drive to the mains, make sure that
the coolant is circulating and has no leaks.
Before connecting the drive to the mains, make sure that
the switchgear enclosure door is closed.
