11.3 Earth-leakage circuit breaker
It is not possible to use a earth-leakage circuit breaker in ECODRIVE03
drive controllers (EN 50178/1994, section: 5.3.2.3).
Protection against indirect contact is implemented by the protective
grounded housing of the components of the drive system.
11.4 Control Circuits for the Mains Connection
The control circuits recommended by Rexroth Indramat specify the
functional principle.
Note:
The choice of control and its effects depends on the extent of
the functions and the operating sequence of facility or
machine. It is therefore the responsibility of the manufacturer
of the installation and machine.
The ready to operate message is output via a relay contact (N/O). If the
Bb contact closes, then the drive is ready to receive power. The contact is
thus a precondition for connecting the mains contactor.
CAUTION
Danger of damage !
The effectiveness of the separation of, the mains
connection via signal contact "Ready to operate Bb" or
the multi-circuits of all ECODRIVE Bb contacts must
be ensured !
See also page 4-48: "Ready to operate contact Bb" resp. page 5-22 for
DKC**.3-016.
See also firmware functional description: "Power shutdown with fault"
Note:
When the mains contactor is shut off the mains coil causes
overvoltages. These can cause the Bb contact to drop
prematurely. To attenuate overvoltage use overvoltage limiters
with diode combinations.
