5.2.3 ELECTRICAL DATA ANNEX 1
Annex 1 (model specific)
to type XI product certificates KEMA 03ATEX1074 X, IECEx DEK 11.0042X
For the combined connection of the different supply, input and output circuits, the installation instructions
of the manufacturer shall be observed. From the safety point of view the circuits shall be considered to be
connected to earth. The following conditions of use shall be observed:
The type XI indicator is classified as group IIB/IIIC. However, classification of the indicator as group IIC is
possible, only under the following conditions:
• The indicator is either supplied by
o the internal supply (type -PC); or
o the external supply connected to terminals 0 and 1 (type -PX or -PD); or
o the circuit supply connected to terminals 7 and 8 (type -AP).
The maximum values for any of those circuits are those as defined for group IIB/IIIC.
• No other active external intrinsically safe circuits may be connected to the indicator, with
exception of circuits connected to terminals 3 and 4 and/or terminals 5 and 6.
The maximum values for any of those circuits are those as defined for group IIB/IIIC
Internal supply
Type -PC
(connector)
For use with the certified replaceable battery type FW-LiBAT-
certified non rechargeable battery in type of protection intrinsic safety Ex ia IIB/IIIC
or Ex ia IIC, with the following maximum values:
Ui = 4 V
Ii = 50 mA
Pi = 200 mW
External supply input
Type -PX and -PD
(terminals 0 and 1)
In type of protection intrinsic safey Ex ia IIB/IIIC or Ex ia IIC, only for connection to
a certified intrinsically safe circuit, with following maximum values:
Ui = 30 V
Ii = 100 mA
Pi = 750 mW
If external circuits are connected to the external supply output (terminals 0 and 2),
the total amount of external capacitance and inductance of the circuits, connected
to those terminals, is added to the effective internal capacitance Ci and inductance
Li of this external supply input circuit.
External supply output
In combination with external
supply (with type -PX or -PD)
(terminals 0 and 2)
In type of protection intrinsic safey Ex ia IIB/IIIC, with following maximum values:
The maximum output values, including the maximum allowed external capacitance
and inductance values, are equal to the parameters of the intrinsically safe circuit,
connected to the external supply input at terminals 0 and 1.
Pulse outputs
Type -OT
(terminals 3 and 4,
terminals 5 and 6)
In type of protection intrinsic safey Ex ia IIB/IIIC or Ex ia IIC, only for connection to
a certified intrinsically safe circuit, with following maximum values:
Ui = 30 V
Ii = 100 mA
Pi = 750 mW
Type -AP
(terminals 7 and 8), and
Type -AF
(terminals 7 and 8 with respect
to terminals 0, 3, 5, 9, 12 and
15)
In type of protection intrinsic safey Ex ia IIB/IIIC or Ex ia IIC (type -AP only), only
for connection to a certified intrinsically safe circuit, with following maximum values:
Ui = 30 V
Ii = 100 mA
Pi = 750 mW
