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), KHDO-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 20mm
and 10cm
. The LED and its terminations must be afforded a degree of protection of at least IP20, and be
2
2
segregated from other circuits and conductors as defined in clause 6 of EN50020: 2002.
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 reengages 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.
Please refer to control panel installation instructions for specific barrier/control panel compatibility information.
