Note:
Assembly and installation work on modules must only be performed with the supply voltage switched off!
Electrical apparatus in explosive/hazardous areas may only be installed and operated by properly trained
personnel. Modifications to devices and electrical connections will eliminate the operational safety/reliability,
remove explosion protection and also void the warranty. Be sure to note the limit values in the EC examination
certificate.
