Controlled outgoing feeder for anti-condensation heating
230 V 1 AC or 120 V 1 AC
Mutually exclusive options
N35
to
N38
A controlled outgoing feeder protected by miniature circuit
breakers is available in the drive for controlling external auxilia-
ries, e.g. the anti-condensation heating for the motor. The power
supply required for the drive, e.g. for the anti-condensation heat-
ing, must be provided externally. Depending on the power that
is required, four different outgoing feeders are available.
The contactor is switched
off
with the ON command at the drive
and switched
on
with the OFF command.
N44
Make-proof grounding switch at drive input
If grounding on the line side is required for safety and protection
reasons, a grounding switch can be ordered with order
code
N44
.
For safety reasons, the drive control locks these grounding
switches against activation while voltage is still present. The
control is integrated into the protection and monitoring circuit of
the drive.
In the event of maintenance work on the drive, it must be en-
sured on the plant side that there is no external voltage present,
e.g. auxiliary voltage for blowers, the cooling system, controller
and closed-loop control and any external drive outputs.
Note:
For 6SR4... drives up to 4.16 kV and up to 140 A, option
N44
is
installed in an additional option cabinet (400 mm wide).
N45
Make-proof grounding switch at drive output
With certain operating modes/configurations of the load
machine (e.g. drive group with gas turbines) or types of motor
(e.g. PEM), operating states are possible where there is a risk
that the motor will feed back energy into the drive. This can lead
to dangerous voltages. In these cases, a grounding switch for
the drive output side can be ordered with order code
N45
.
For safety reasons, the drive control locks the grounding switch
against activation while voltage is still present. The control is
integrated into the protection and monitoring circuit of the drive.
Note:
Options
N44
and
N45
are recommended for applications within
Europe.
N50
Internal cabling with halogen-free cables
With option
N50
, only halogen-free cables are used for cabling
inside the drive. The insulating materials and color coding are in
compliance with IEC standards (EN 50178/VDE 0160
(IEC 62103) and EN 60204-1/VDE 0113-1 (IEC 60204-1)).
Note:
Only halogen-free cables are used for units manufactured in
Nuremberg, Germany. Option
N50
must be ordered.
N75
Power supply for external devices 24 V DC/2.5 A
With option
N75
the drive is delivered with a power supply unit
for 24 V DC auxiliaries. It provides 6 output terminals each for
+24 V and 0 V. The total power consumption across all output
terminals is limited to 2.5 A.
