ProMinent Sigma X Supplementary Instructions

4 Installation
All devices that are members of the bus system must be connected in a
line. There are up to 32 possible positions (master, slaves, repeaters).
At both the beginning and end of the cable, the bus must be terminated
with a terminating resistance.
For the PROFIBUS
®
cable, use a screened, twisted-pair cable in con‐
formity with EN 50170 (cable type A).
Use of shielding which is earthed at one end prevents
low-frequency ground loops. Shielding earthed at one
end has no effect in combating HF magnetic pick-up.
Shielding earthed at both ends as well as twisted con‐
ductors work to counter magnetic HF pick-up, but have
no effect against electrical HF pick-up.
For PROFIBUS
®
, it is recommended to establish a bilateral, low-induc‐
tance (i.e., large area and low-impedance) connection with the protective
earth.
The overall length of the bus cabling without repeaters varies according to
the desired data transmission rate:

The PROFIBUS
®
module has a M12 industry socket for connection to the
PROFIBUS
®
cable. The pin configuration complies with the PROFIBUS
®
standard - see below - which means that commercially available bus plugs
may be used. Please note that cable connections made with these plugs
generally only meet the requirements for protection against contact and
moisture according to IP 20!
An installation compliant with the protection against contact and moisture
according to IP 65 is possible, since the M12 industry socket of the PRO‐
FIBUS
®
module allows this. However, in this case the PROFIBUS
®
cable
must also be fitted with M12 industry plugs in conformity with IP 65.
In order to achieve the IP 65 degree of protection for the PROFIBUS
®
cable installation, special Y-adapters or terminating adapters must be
installed (e.g. - see below).
