• Each assembly must be terminated at the right hand end with a KL9010 bus end terminal, to ensure the protection class and ESD protection. Fig. 3: Spring contacts of the Beckhoff I/O components Version: 2.1.0 KL2784/KS2784, KL2794/KS2794... -
Page 13: Installation On Mounting Rails
To mount the mounting rails with a height of 7.5 mm under the terminals and couplers, you should use flat mounting connections (e.g. countersunk screws or blind rivets). KL2784/KS2784, KL2794/KS2794 Version: 2.1.0... -

EL91xx, EL92xx) interrupt the power contacts and thus represent the start of a new supply rail. PE power contact The power contact labeled PE can be used as a protective earth. For safety reasons this contact mates first when plugging together, and can ground short-circuit currents of up to 125 A. Version: 2.1.0 KL2784/KS2784, KL2794/KS2794... -

Power Feed Terminals can be released and pulled at least 10 mm from the group of terminals. WARNING Risk of electric shock! The PE power contact must not be used for other potentials! KL2784/KS2784, KL2794/KS2794 Version: 2.1.0... -
Page 16: Connection
Insert the new component and plug in the connector with the wiring. This reduces the installation time and eliminates the risk of wires being mixed up. The familiar dimensions of the terminal only had to be changed slightly. The new connector adds about 3 mm. The maximum height of the terminal remains unchanged.
