5 ADDENDUM TO IECEx CERTIFICATE OF CONFORMITY IECEx BKI Page 1 of 2 1. Description The terminal box, types STB and Typ NXT, consists of a stainless-steel enclosure designed to Increased Safety e type of protection or IP66. It is to accommodate terminals for intrinsically safe and non-intrinsically safe circuits. The box area intended for intrinsically safe circuits is marked, e.g. by a light-blue colour. Connection is by means of explosion-proof cable entries. The empty enclosure as well as all integrated elements and extension elements have been tested and certified under a separate certificate. 2. Type assortment 2.1 Terminal boxes STB _, 2._, 3._ 4._, 5._, 6._, 7._, 8._, 9._ 2.2 Terminal boxes NXT _, 2._, 3._ 4._, 5._, 6._, 7._, 8._, 9._ Code for manufacturer Enclosure size 4._, 5._ Length 6._, 7._ Width 8._, 9._ Depth Code for manufacturer Enclosure size 4._, 5._ Length 6._, 7._ Width 8._, 9._ Depth 3. General parameters 3.1 Type STB terminal boxes verion (9 size) Sizes Length Width Depth smallest 120 mm 120 mm 80 mm largest 380 mm 380 mm 220 mm Technical data Rated voltage* up to 750 V Rated current* max. 250 A * depending on the type of terminal and explosion-proof components used Rated values are maximum values, the actual electrical values are determined by mounted electrical apparatus. Within these limiting values complying with the appropriate standards the manufacturer specified the final values dependent on power supply specifications, operating mode, utilization category, etc. 3.2 Type NXT terminal boxes version (40 size) Sizes Length Width Depth smallest 260 mm 260 mm 160 mm largest 1050 mm 610 mm 205 mm Technical data Rated voltage* up to 1100 V Rated current* max. 500 A Rated cross section max. 240 mm 2 * depending on the type of terminal and explosionproof components used Rated values are maximum values, the actual electrical values are determined by mounted electrical apparatus. Within these limiting values complying with the appropriate standards the manufacturer specified the final values dependent on power supply specifications, operating mode, utilization category, etc. 4. Ambient temperature subject to the sealing used Ambient temperature -55 C up to +55 C (T5) -55 C up to +40 C (T6) (with HT100 sealing) 5. Ingress protection IP66 to IEC Notes for manufacturing and operation For the maximum number of conductors for each enclosure size, which is subject to the cross section and the permissible continuous current, reference is made to the data sheets. Equipment designed to Intrinsic Safety I type of protection shall be installed in such a way that, the clearance and creepage distances specified in IEC :2003 between intrinsically safe and non-intrinsically safe circuits are complied with. If the clearance requirements specified in IEC :2006, are not complied with, terminals and wiring of Increased Safety e standard shall also be used for the intrinsically safe circuits. When connecting more than one intrinsically safe circuit, the rules and regulations for interconnection shall be duly observed.
