Wiring diagram for
connecting
non-i
ntrinsically
safe quipment to AAC 00xx
or AAC 03**
Notes
1. XEXT1 and/or
XEXT2 can be used
for connection of non-
intrinsically
safe equipment via Z-
barriers. As
an example the wiring diagram
shows a connetion to XEXT2.
2. Series switching of the types
Pepperl+Fuchs Z757 with Pep-
perl+Fuchs Z966H
(BAS 01 ATEX
7005 and IECEx S06.0012 xx) is
permitted as shown in the following
diagrams.
3. Barrier must be installed as in-
structted by the manufacturer’s
control drawing.
4. Caution
: Use connection XEXT1
either for charging (pin 4,5)
outside
the hazardous area or the
RS485
port (pin 1, 2,
3). Using XEXT1 for
both applications at the same time
is not permitted.
5. Caution
: Use connection XEXT2
either for the relay output (pin 4, 5,
6) or the RS485 port (pin 1, 2,
3).
Using XEXT2 for both applications
at the
same time is not permitted.
6. Warning: Substitution of compo
-
nents may impair intrinsic safety.
7. Cable Parameters:
Use Belden
3107A, 2 x 2 AWG22. Maximum
length = 25 m = 82 ft between
AAC 00xx and the Z-barriers.

Notes
1.
Caution: Only connect
galvanically isolated, intrinsically safe electric
circuits of protection type Ex ia IIC with linear output characteristics
that meet the safety parameters of AAC 03**.
All of the 4 circuits must be infallibly isolated from each other.
2.
Caution: Operation
with an intrinsically safe power supply to XEXT3
is only permitted without simultaneous inductive charg-ing, or
simultaneous power charging via the XEXT1 connection.
3.
Warning: Live maintainance is not permitted in Zone 0 areas.
4.
Warning: Substitution of components may impair intrinsic safety.
5.
Cable Parameters:
If cable parameters are unknown, use the following parameters:
Cable Capacitance: C
c
= Ccable = 60 pF/ft (200 pF/m)
Cable inductance: L
c
= Lcable = 200 nH/ft (660 nH/m)
The cable must maintain infallible segregation of the 4 circuits.
