NOTICE
Removing the push-pull cable connectors
It is not permissible to remove the push-pull cable connector for 1L+/2L+ while ET 200pro is
in operation! Always switch off the 1L+ electronic/encoder supply and the 2L+ load voltage
supply before you remove or insert the push-pull cable connector.
Note
If you remove the push-pull cable connector used for looping through of PROFINET IO or
1L+/2L+, the downstream modules on PROFINET IO will fail or will no longer be supplied
with power.
Covering unused sockets
Cover all unused push-pull sockets with caps in order to achieve degree of protection IP65,
IP66, or IP67.
