Prescribed Installation Position; Fig. 14 Power Contact On Left Side - Beckhoff KS2535, KL2545 Manual

Mounting and wiring
Fig. 14: Power contact on left side
Possible damage of the device
Note that, for reasons of electromagnetic compatibility, the PE contacts are capacitatively coupled to the
mounting rail. This may lead to incorrect results during insulation testing or to damage on the terminal (e.g.
disruptive discharge to the PE line during insulation testing of a consumer with a nominal voltage of 230 V).
For insulation testing, disconnect the PE supply line at the Bus Coupler or the Power Feed Terminal! In or-
der to decouple further feed points for testing, these Power Feed Terminals can be released and pulled at
least 10 mm from the group of terminals.
Risk of electric shock!
The PE power contact must not be used for other potentials!

Prescribed installation position

Constraints regarding installation position and operating temperature range
When installing the terminals ensure that an adequate spacing is maintained between other components
above and below the terminal in order to guarantee adequate ventilation!
Prescribed installation position
The prescribed installation position requires the mounting rail to be installed horizontally and the connection
surfaces of the EL/KL terminals to face forward (see Fig. "Recommended distances for standard installation
position").
The terminals are ventilated from below, which enables optimum cooling of the electronics through
convection. "From below" is relative to the acceleration of gravity.
