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

The Surge Voltage Protection Units, PLUGTRAB PT 4-EX(I)-24DC-ST, PLUGTRAB
PT 2xEX(I)-24DC-ST, TERMITRAB TT-ST-M-EX(I)-24DC, TERMITRAB TT-EX(I)-24DC and TERMITRAB TT-EX(I)-M-24DC serve to limit eventual surge voltages in intrinsically safe circuits.

PLUGTRAB PT 4-EX(I)-24DC-ST and PLUGTRAB PT 2xEX(I)-24DC-ST consist out of a fixed mounted part and a plug-in unit provided with a (for each Unit Model) unique mechanical key.

The open side of TERMITRAB TT-ST-M-EX(I)-24DC is closed by cover type TT-D-ST-BU. With that a degree of protection IP20 is obtained.

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.

The attachment provides the thermal and electrical data.

 
CONDITIONS OF CERTIFICATION: 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 (TERMITRAB) or 700 V (PLUGTRAB) gas tube.

For application in explosive dust atmospheres:

The Surge Voltage Protection Unit shall be installed in an enclosure which as a minimum complies with the requirements of IEC 60079-0 for electrical equipment of Group III, providing a degree of protection of at least IP6X in accordance with IEC 60529.

For application in explosive gas atmospheres:

The Surge Voltage Protection Unit shall be installed in an enclosure providing a degree of protection of at least IP20 in accordance with IEC 60529.  When the environmental conditions are such that a higher degree of protection is required, this shall be taken into account.
