Chapter 6 — Start-Up
Safety Precautions
Before start-up, note the following directions and warnings:
WARNING
Internal components and circuit boards of the drive (except
for the galvanically isolated I/O terminals) 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 +/- are live when the drive is connected to DC
supply, 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 power supply.
Do not make any connections when the drive is connected
to the power supply.
After having disconnected the drive, wait until the fan stops
and 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 open the cover before the time has expired.
Before connecting the drive to power supply, make sure
that the drive’s front cover is closed.
