Positioner SIPART PS2/SIPART PS2 PA
C79000-G7476-C150–01
3.4.2 Connection variants not protected from explosion hazard (devices
with PROFIBUS PA)
!
Warning
The applicable regulations for electrical installation must be observed,
in particular, in zones subject to explosion hazard
❑ the regulation about electrical equipment in zones subject to explo-
sion hazard. The erection guidelines of the country in question must
be observed.
❑ the regulation about erection of electrical equipment in zones sub-
ject to explosion hazard (DIN VDE 0165)
❑ the certificate of conformity
❑ It is necessary to check whether the auxiliary power supplied by the
coupler matches the value specified on the rating plate of the SI-
PART PS2 PA and in the Ex certification.
If the intrinsically safe version is operated with an operating voltage of
more than 24 V by mistake, the device must no longer be used for in-
trinsically safe applications.
The positioner is powered via the PROFIBUS PA by the DP/PA coupler
or DP/PA link. The devices draw their electrical auxiliary power from a
power supply unit with SELV (safety extra–low voltage).

Note
The following generally applies to laying the bus cable:
❑ Lay cables separated from cables carrying > 60 V
❑ Avoid the vicinity of large electrical equipment
❑ Only use recommended cable types
❑ The specifications only apply to properly installed equipment
Only use a shielded, two–conductor cable as the bus cable.
The recommended cable types are:
Ex i applications:
Siemens 6XV1 830–5AH01 (color blue)
Non Ex applications: Siemens 6XV1 830–5BH10 (color black)
The mechanical and electrical data of these two cable types are identi-
cal.
1. Strip back the bus cable insulation as shown in Fig.3-11.
2. Open the housing of the positioner by loosening the four screws of
the cover.
