1. Terminals L1, L2 are only available for the 80/104 kW and 120/156 kW I/R
modules.
In this case, I
n fuse
must be
4 A. Version: gL.
2. For a coupling to a numerical control, X131 must be connected with the NC
reference potential. This cable is routed in parallel to the speed setpoint ca-
ble. For a digital drive group with 840C/840D, leave terminal X131 open–cir-
cuit.
3. Signaling contact, of the internal line contactor
Terminals 111/113 NO contact
Terminals 111/213 NC contacts
Terminals 111/213 positively driven to the load contacts,
refer to NE modules
4. Jumpers inserted in the equipment when supplied
!
Caution
5. For the 80/104kW or 120/156kW I/R modules, if the line voltage at terminal
L1, L2 fails, or fuses F1, F2 rupture, then the I/R module pulses are inhibi-
ted, and the internal line contactor drops–out. This is indicated by the sup-
ply fault LED, the ready relay and via the contactor signaling contacts. In
this case, to re–close the internal line contactor, terminal 48 must be de–
energized, and after
1 sec. re–energized or the drive must be powered–
down/powered–up.
6. If an 80/104kW or 120/156kW I/R module is used, jumper terminal 9/48
must be removed, and a switch used (due to Point 5). The switch is not
required if the drive converter is powered–down and up again using the
main switch (supply).
7. Max. cable length for 1.5 mm
2
cross–section: 50 m (2–wire cable)
This should be linearly decreased for lower cross–sections.
8. A maximum of 6 x terminals 48 may be connected in parallel, to shutdown
max. 6 NE modules using a leading contact of the main switch.
Max. cable length for 1.5 mm
2
cross–section: 150 m (2–conductor cable).
Linearly reduced for lower cross–sections.

If more than 6 NE modules are to be connected to a main switch, then an exter-
nal 24V supply must be provided. Current drain terminal 48=35 mA; the mini-
mum input voltage of terminal 48 must be observed (13 V). Additional loads
connected to the external 24 V power supply must be provided with an overvol-
tage limiting circuit
(e.g. free–wheeling diode).
