4.2
Wiring
It is recommended to use conduc-
tors with section and length ade-
quate
to
the
terminals,
and distances involved, ensuring
that the conductors are not exces-
sively tight, that their positioning
avoids potential cuts or squashing
and that they are not in the way of
people or things.
4.3
Po we r s u p p l y
Connect the A1 & A2 terminals to
the power supply source via the
E-STOP device(s).
4.4
E- STOP c o nne c t io n
The NA13CT safety module can
be connected to one or more sin-
gle-channel or double-channel E-
STOP
devices

The E-STOP contact(s) must be
closed when the E-STOP button is
not
pushed,
open
STOP is pushed.
The contacts of the E-STOP must
be connected between the power
supply terminals of the midule (A1
and eventually A2) and the power
supply source, so that when the
E-STOP
is
pushed
module is switched off.

START Circ u it
The safety module can be config-
ured for manual START (not mon-

T o set up the manual START con-
figuration, it is necessary to con-
nect a N.O. pushbutton to the S1-
S2 terminals, while to set up the

OPERATING MODE
With manual START configuration,
the safety outputs close and the
auxilary output opens when the E-
STOP is not pushed and the N.O.
START pushbutton is pressed.
With automatic START configura-
