General Technical Specifications

Standards ComplianceThe national and international standards listed below were used to determine appropriateperformance specifications and testing for the S7-200 family of products. Table A-1 defines thespecific adherence to these standards.

- European Community (CE) Low Voltage Directive 73/23/EECEN 61131--2: Programmable controllers -- Equipment requirements

- European Community (CE) EMC Directive 89/336/EEC

Electromagnetic emission standardEN 61000--6--3: residential, commercial, and light industryEN 61000--6--4: industrial environment

Electromagnetic immunity standardsEN 61000--6--2: industrial environment

- Underwriters Laboratories, Inc.: UL 508 Listed (Industrial Control Equipment),Registration number E75310

- Canadian Standards Association: CSA C22.2 Number 142 (Process Control Equipment)

- Factory Mutual Research: Class Number 3600, Class Number 3611, FM Class I, Division 2,Groups A, B, C, & D Hazardous Locations, T4A and Class I, Zone 2, IIC, T4.

- European Community (ATEX) Atmospheres Explosibles Directive 94/9/ECEN 60079--0 General requirementsEN 50020 Intrinsic safety ‘i’EN 60079--15 Type of protection ‘n’

ATEX Directive applies to CPUs and expansion modules with a rated voltage of 24 VDC. Itdoes not apply to modules with AC power systems or Relay outputs. Consult your localSiemens representative for a list of ATEX approved modules.

TipThe SIMATIC S7-200 series meets the CSA standard.

The cULus logo indicates that the S7-200 has been examined and certified by UnderwritersLaboratories (UL) to standards UL 508 and CSA 22.2 No. 142.

Maritime ApprovalsThe S7-200 products are periodicallysubmitted for special agency approvalsrelated to specific markets and applications.This table identifies the agency andcertificate number that the S7-200 productshave been approved for. Most S7-200products in this manual have beenapproved for these special agencyapprovals. Consult your local Siemensrepresentative if you need additionalinformation related to the latest listing ofexact approvals by part number.
