50 TZIDC, TZIDC-110, TZIDC-120 42/18-84-EN
Cable and wire entries that meet the requirements of EN 61241-11 for Category II 2 D as well
as the ambient temperature range must be used.
Variants with special certification confirming that they meet the requirements for "flameproof
enclosure" type of protection may no longer be used as intrinsically safe if they are used with
"flameproof enclosure" type of protection.
