2.3 Terminals
2.3.1 Removable Terminal Blocks
The KC and KF devices have removable terminal blocks.
The removable terminal blocks simplify connection and control cabinet assembly.
The terminal blocks offer space for the connection of leads with core cross-sections
of up to 2.5 mm
2
(14 AWG). The terminal blocks are coded with red coding pins
so misconnection of terminal blocks are eliminated.
Observe the tightening torque of the terminal screws. The tightening torque
is 0.5 Nm to 0.6 Nm.
The 20 mm and 40 mm wide KF devices are factory-equipped with screw terminals.
The KC devices are available with screw terminals or spring terminals. The order designation
of the versions of the KC devices with spring terminals has the extension .SP.
As an alternative to the factory-equipped terminal blocks the devices can be used with other
terminal blocks:
• Terminal blocks with screw terminals
• Terminal blocks with screw terminals and test plug socket
• Terminal blocks with spring terminals and test plug socket
These terminal blocks are available as accessories. The terminal blocks can be easily coded
with KF-CP coding pins (available optionally).
