• ATEX Explosion Proof Ex db_tb (code E2)
• ATEX Intrinsic Safety Ex ic_tc (code E3)
• Combined ATEX Ex ia, Ex db_tc and Ex ic_tc (code EW)
• IECEx Intrinsic Safety Ex ia (code E8)
• IECEx Explosion Proof Ex db_tb (code E9)
• IECEx Intrinsic Safety Ex ic_tc (code ER)
• Combined IEC Approval Ex ia and Ex db_tb (code EH)
• Combined IEC Approval Ex ia, Ex db_tb and Ex ic_tc (code EI)
• FM Approvals (Canada) approval (XP, DIP, IS, NI) (code E4)
• FM Approvals (US) approval (XP, DIP, IS, NI) (code E6)
