Safety management note | NOTICE: Observe installation and safety instructions!Only to be used by electricians!Do not work under voltage/load!Use only for proper use!Observe national regulations/standards/guidelines!Observe technical specifications for the products!Observe the number of permissible potentials!Do not use damaged/dirty components!Observe conductor types, cross-sections and strip lengths!Insert conductor until it hits the product‘s backstop!Use original accessories!To be sold only with installation instructions! | Safety information | The permissible operating voltage of the connector with carrier (440?V or 275?V) depends on the mounting type. |
Safety information 2 | Only approved in conjunction with a mounting carrier (221-511). Other carriers are possible, see certificate/file.The connectors must be installed in an enclosure meeting the requirements of a recognized protection type per EN?60079-0, Section 1 or EN?60079-31.When installing the connectors in an enclosure of protection type “eb” (increased safety) per EN?60079-7, the clearances and creepage distances of Table 2 for this standard must be observed. See point 1 for the use of accessories. The connectors can be used both in Group II and Group I, as the standard requirements are identical in this case.The use of these components requires a new assessment by a notified certification agency. | Clamping units | 3 |
