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 = 0.66 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:
P & F Smart Fire Detector Isolator Type KFDO-CS-Ex1.54-Y72221
One channel from: P & F Smart Fire Detector Isolator Type KFDO-CS-Ex2.54-
Y72222 (BAS00ATEX7087X)
2. The capacitance and either inductance or inductance/resistance (L/R) ratio of
the cable connected to the hazardous area terminals of barrier 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. to 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 equipment, for a
period of one minute without breakdown. This note does not apply when using
an isolation barrier.
