Description of the interfaces and functions
Switch S1 to set various functions is provided on the upper side of the NE and
monitoring module or on the front side/panel for the UI module 5 kW; refer to
Chapter 6.3.
EN–
Reference potential for the enable voltage terminal 9, non–floating (with electri-
cal isolation) (connected to the general reference ground terminal 15 through
10 k
Ω
). Terminal 19 is not permitted to be connected to terminal 15. (Connect
to the PE bus or X131.)
When controlling the enable signals using electronic outputs that switch to high
(PLC), terminal 19 must be connected to the 0 V reference potential (ground) of
the external power supply.
The circuits/power source must satisfy the requirements for PELV (Protection
Extra–Low Voltage) functional extra–low voltage with safe separation in accor-
dance with EN 60204–1; 6.4.
EN+
Only use the +24 V enable voltage for the internal enable signals of the NE and
drive modules.
Maximum power supply load: 500 mA
(corresponds to 8 EP; 1 optocoupler input requires 12 mA, for UI 5 kW ––> 1 A)
Start
This terminal has the highest priority. A defined power–on and power–off se-
quence of the NE module is initiated using terminal 48.
If terminal 48 is enabled (energized), then internally, the pre–charging sequence
is initiated.

– 50 V).
After the DC link has been charged, then, simultaneously
after 500 ms ––> the pre–charging contactor is opened and the main con-
tactor is closed.
after 1 second ––> the internal enable signals are then issued.
If terminal 48 is de–energized, then initially, after approx. 1 ms, the internal
pulse enable signals are inhibited and then the DC link is electrically isolated
from the line supply delayed by the drop–out time of the internal line contactor.
If terminal 48 is opened (enabled) during the load operation, the load operation
is first completed. The inhibit functionality for terminal 48 does not takes effect
until the load operation is complete, provided terminals NS1–NS2 are jumpered.
Coil circuit of the internal line and pre–charging contactor
If the line contactor is opened (de–energized) by interrupting the coil circuit us-
ing electrically isolated (floating) contacts, then the DC link is safely and electri-
cally disconnected from the line supply (signal contact, terminals 111–213 must
be interrogated).
The terminals have a safety–relevant function. The shutdown using terminals
NS1–NS2 must be realized at the same time as or delayed with respect to ter-
minal 48 start (refer to Section 8.7 Circuit examples = 2 and = 4).

Pulse enable
For the pulse enable and inhibit functionality, this terminal has the highest prior-
ity. The enable and inhibit functions are effective after approx. 1 ms simulta-
neously for all of the modules including the NE module. When the signal is with-
drawn, the drives ”coast down” unbraked.
