NOTE
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.
WARNING
Risk of electric shock!
The PE power contact must not be used for other potentials!
3.2 Connection
3.2.1 Connection system
WARNING
Risk of electric shock and damage of device!
Bring the bus terminal system into a safe, powered down state before starting installation, disassembly or
wiring of the bus terminals!
Overview
The Bus Terminal system offers different connection options for optimum adaptation to the respective
application:
• The terminals of ELxxxx and KLxxxx series with standard wiring include electronics and connection
level in a single enclosure.
• The terminals of ESxxxx and KSxxxx series feature a pluggable connection level and enable steady
wiring while replacing.
• The High Density Terminals (HD Terminals) include electronics and connection level in a single
enclosure and have advanced packaging density.
