Fig. 16: Overview terminal connectors XI - Intrinsically Safe applications.
Remarks power supply options:
Type PC: offers - additional to type PX - an internal Intrinsically Safe lithium battery. This ATEX
certified battery (FW-LiBATT-xxx) may be changed in hazardous area.
Type PD: offers - additional to type PX - a sensor supply terminal (terminal 6) which offers the same
voltage as connected to terminal 5 (internally linked).
Type PX: as standard, all intrinsically product are supplied with terminal 4 and 5 to power the
product externally.
Type PL: the unit will be powered from the 4-20mA input signal. Terminal 4-6 are not available.
