The connections between the auxiliary voltage modules comprise two cables, i.e. one 4-wire cable for the line voltage
V
Line
2 AC and the voltage 230 V 2 AC, and a shielded, 2-wire cable for 24 V DC.
The standard assignments of voltages to the connecting cables are given in the table below.
Cable Designation Assigned voltage
4-wire L1 Line voltage:
· 380 V to 480 V AC or
· 500 V to 690 V AC
L2
L1 230 V AC
N
2-wire P24 24 V DC for electronics supply

Assignments of voltages to connecting cables
The auxiliary voltage supply system is used in the following air-cooled S120 Cabinet Modules:
· Smart Line Modules
· Active Line Modules
· Booksize Base Cabinets
· Motor Modules in Chassis format
· Central Braking Modules
· Auxiliary Power Supply Modules
Cabinet Modules which are not equipped with an auxiliary voltage supply system are supplied with cables for making
the connection to the auxiliary voltage module in adjacent Cabinet Modules.
