( Stop!
The drive controller contains electrostatically sensitive
components!
The personnel must be free of electrostatic charge prior to
assembly and service operations.
6.2.1 Protection of persons
{ Danger!
Before working on the controller check that no voltage is applied
to the power terminals, the relay output and the pins of the FIF
interface
l because the power terminals U, V, W, BR1, BR2 and the pins of
the FIF interface remain live for at least 3 minutes after mains
switch-off.
l because the power terminals L1, L2, L3; U, V, W, +UG, -UG,
BR1, BR2 and the pins of the FIF interface remain live when the
motor is stopped.
l because the relay outputs K11, K12, K14 can remain live when
the controller is disconnected from the mains.
The use of e.l.c.bs will be dealt with later in this Manual
(¶ 6.2-4) .
All pluggable connection terminals must only be connected or disconnected
when no voltage is applied!
l Replace defective fuses with the prescribed type only when no voltage is
applied.
l In DC-bus connection all controllers must be inhibited and disconnected
from the mains.
Make a safety connection between the controller and mains only via a contactor
at the input side.
Use of e.l.c.bs
Pluggable terminal strips
Replace defective fuses
Disconnect controller from the
mains
