Notes on the "Non Incendive“ ignition protection class
The KLD2-PR-NI1.IEC power repeater and KLD2-STR-NI1.13.225.IEC
power supply are designed according to ignition protection class EEx n L IIC.
The devices are approved for installation in Class 1 Division 2. They have an electro-
nic current limitationation on the field side. Field devices of the bus transmission line
can therefore be connected or disconnected on the field side under voltage, for ex-
ample.
A distinction must be made of 2 cases on the host side for the FOUNDATION Field-
bus:
1. There are no field devices on the transmission line connected between the host
and power repeater
2. Field devices are connected to the transmission line between the host and the po-
wer repeater.
In the first case, no power is supplied through the transmission line. This causes the
maximum electrical power that is available on the bus line to be so low that no special
wiring technique needs to be used for usage in Class 1 Division 2.
For installation and operation of power repeaters with intrinsically safe
interface, be certain to observe the Certificates of Conformity for the
unit as well as applicable setup and installation requirements (DIN EN
50020, DIN VDE 0165) plus the FISCO Model (PTB Report W-53) or
the Entity Model.
The PROFIBUS PA Installation Guidelimitation must be observed for
the installation of the PROFIBUS PA Segment (available from the PRO-
FIBUS user organization).
Please note the FOUNDATION Fieldbus Application Guide 31.25 kbit/s
Intrinsically Safe System (available from the Fieldbus Foundation) for
installing the FOUNDATION Fieldbus.
