Usage area
The bus connection unit f orms the basis for the bus options and IO - expansions of model SK TU4-.
The terminal strip is divided into three potential levels . The functions of the individual term inals are
dependent upon the se lected field bus or IO - expansion and are not defined until both elem ents are
joined together (BUS - connection un it and field bus or IO expansion). The BUS - connec tion unit can
be fitted to or in the immediate vicinity of a frequency converter (SK 180E … SK 2xxE).

Installation
Installation location To the left or right of the frequency converter connection unit.
Alternatively using the wall mounting kit SK TIE4-WMK-TU (Mat no.: 275 274 002,
TI 275274002) near the converter
Mounting Using screw connection (4 x hexagon socket M4 x 20)
ATTENTION
Ensure that no leaks are present during installation (assembly, cable leadthroughs, cable glands) in order to
avoid penetration by moisture and therefore the risk of corrosion and short circuiting.
