Schedule
 
EQUIPMENT:
Equipment and systems covered by this certificate are as follows:
 

The Surge Arrester, Model D9024S serve to limit eventual surge voltages in intrinsically safe circuits. Several units for different intrinsically safe circuits may be mounted next to each other. The earth connection can be made via the mounting foot to a normalized metal mounting rail and via a terminal.

Electrical data

Input circuit (terminals 1 and 2): in type of protection intrinsic safety Ex ia IIC or Ex ia IIIC, only for connection to a certified intrinsically safe circuit with the following maximum values:
Ui = 30 V; Ii = 250 mA; Pi = 750 mW; Ci = 2 nF; Li = 1 μH.

Output circuit (terminals 3 and 4):
in type of protection intrinsic safety Ex ia IIC or Ex ia IIIC. The output parameters are equal to the output parameters of the external intrinsically safe circuit connected to the input circuit. For the determination of the maximum allowed external capacitance (Co) and inductance (Lo), the values of the internal capacitance (Ci) and inductance (Li) shall be taken into account. 

 
SPECIFIC CONDITIONS OF USE: YES as shown below:
 
The insulation between the intrinsically safe circuits and earth is not capable of withstanding a 500 Vac test voltage, however this is only caused by the 600 V gas discharge tubes.

Ambient temperature range:
-40 °C to +40 °C for T6 / T85 °C;
-40 °C to +50 °C for T5 / T100 °C;
-40 °C to +80 °C for T4 / T135 °C.
