conductors separately from the
power conductors.
- Avoid installation during storms.
- Do not dispose of the packaging
in the environment.

IRING
It is recommended to use conduc-
tors with section and length ade-
quate to the terminals, currents
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.
The models named “SA” and “SC”
are equipped with fixed screw ter-
minals for direct wiring on the
module.
The modules named with “DA” and
“DC” are equipped with plug-in ter-
minals, that allow the wiring on
female connectors far from the
module.
Once wired-on, the female con-
nectors can be connected to the
male ones fixed on the module.
T
ERMINALS CODING
The plug-in terminals of the “DA”
and “DC” models are coded so that
it is possible only one combination
to connect ALL the female connec-
tors on the corresponding male.
P
OWER SUPPLY
Connect the A1 & A2 terminals
respectively to the positive and
negative poles of the DC power
supply source. The negative sup-
ply terminal of the ESPE must be
connected to the same negative
pole of the DC power supply sour-
ce to which is connected the A2
terminal of the safety module (see
examples in this manual).
I
NPUT
The module is designed to be dri-
ven (input terminals S11 and S22)
by two static PNP inputs: each
ESPE PNP output transistor has
the emitter internally connected to
the supply of the ESPE, so each
ESPE output has only one wire
coming from the collector. With this
configuration the system
light barrier can reach safety cate-
gory 4 according to EN 954-1 and
EN13849-1.
The light barrier can be also driven
by only one static PNP input (see
the examples in this manual): with
this device the system
light barrier can reach safety cate-
gory 2 according to EN 954-1 and
EN13849-1.
The safety module is enabled to
close the safety outputs only if both
input contacts are operated.
The connection between the ESPE
and the safety module depends on
the ESPE outputs type as listed
below:
-
ESPE with two one-wire outputs
(PNP-type or relay-type)
: con-
nect one output to the S11 termi-
