Typical 5451EIS System Diagram
Safe area apparatus, which is
unspecified except that it must
not be supplied from or contain
under normal or abnormal
conditions a source of potential
with respect to earth in excess of
253 Vrms or 253 VDC
Notes:
1. Any single channel shunt zener diode safety barrier or single channel of a dual
channel shunt zener diode safety barrier certified by Baseefa or any EEC approved
certification body to [EEx ia] IIC having the following or lower output parameters:
Uz = 28V; Imax: out = 93.3 mA; Wmax: out = 0.67 W
In any safety barrier used, the output current must be limited by a resistor "R",
such that Imax:out = Uz/R. Or any of the following isolation barriers may be used:
MTL : MTL4061 (BAS01ATEX7176), MTL5061 (BAS01ATEX7160)
Pepperl + Fuchs : KFDO-CS-Ex1.51P (BAS98ATEX7343), KFDO-CS-
Ex2.51P (BAS98ATEX7343)
2. The capacitance and inductance or inductance/resistance (L/R) ratio of the
hazardous area cables between the power terminals 2 and 4 (B401 base) must
not exceed the values shown in Table 1.
3. The installation must comply with the appropriate national installation requirements,
e.g. in the U.K. BS5345:Part 4:1977 or BSEN60079-14: 1997.
4. The electrical circuit in the hazardous area must be capable of withstanding an
A.C. test voltage of 500 VRMS to earth or frame of the apparatus for one minute.
This note does not apply when using an isolation barrier.
5. An external light emitting diode (LED) may be fitted to terminals 2 and 1 (B401
base). The surface area of the LED must lie between 20mm2 and 10cm2. The
LED and its terminations must be afforded a degree of protection of at least IP20,
and be segregated from other circuits and conductors as defined in clause 6 of
EN50020: 2002 and clause 5.7 of EN60079-11: 2007.
6. The zone wiring of the detector bases should be checked before the detector
heads are installed. To make this possible, this base contains a special spring-
type shorting jumper. After a detector base is properly wired and mounted to an
electrical box, make sure that the shorting spring is in contact with terminals 2
and 3. This temporary connection permits the wiring of the loop to be checked
for continuity before installation of the detector heads. The shorting spring in the
base automatically disengages when the detector head is removed from the base.
DO NOT remove the shorting spring since it re-engages as the detector head is
turned in the base, completing the circuit.
7. The system must be marked with a durable label. The label should appear on
or adjacent to the principle item of electrical equipment in the system or at the
interface between intrinsically safe and non intrinsically safe circuits. This should
show Baseefa 03Y0180 and SYST or System.
