7.3.3.1

Customer terminal block

In contrast to air-cooled S120 Cabinet Modules, liquid-cooled S120 Cabinet Modules do not have a customer
terminal block -X55 as a signal interface to the higher level control.
For this reason, the signal leads from and to the higher level control must be directly connected to the appropriate
modules in the cabinet on liquid-cooled S120 Cabinet Modules:
- Control Unit (if installed)
- Control Interface Module CIM:
- Safe Brake Adapter (if installed):
7.3.3.2

Auxiliary voltage supply system

In contrast to the air-cooled S120 Cabinet Modules, the liquid-cooled Cabinet Modules have a modified auxiliary
voltage supply system for distributing auxiliary voltages in the cabinet line-up. This is because the 1AC line voltage
required to supply the fans in air-cooled Cabinet Modules can be omitted from the liquid-cooled Cabinet Modules so
that the latter require only two auxiliary voltages (230 V 1AC and 24 V DC).
The auxiliary voltage supply system for liquid-cooled Cabinet Modules consists of 2 terminal blocks and the
associated connecting cables.
The Line Connection Modules of Basic Line Connection Modules and Active Line Connection Modules provide
means of supplying auxiliary power. The auxiliary voltages are either fed in to the Line Connection Module from an
external source via terminal -X100, or generated in the Line Connection Module itself by option K76 "Auxiliary voltage
generation (in the Line Connection Module)". In large-scale installations with high auxiliary power requirements, it
may be useful to install an Auxiliary Power Supply Module (available soon).
The maximum current into the auxiliary voltage supply system is 28 A in each case for 230 V 1AC and 24 V DC. If the
total power requirement of the cabinet line-up exceeds the maximum load capability, the auxiliary voltage supply
system must be divided into segments and several infeed points selected.
The auxiliary voltage supply system of each Cabinet Module comprises 2 terminal blocks and the associated
connecting cables. -X140 is the terminal block for 230 V 1AC and -X150 for 24 V DC. The required auxiliary voltages
can be picked off from the terminals or transferred to the terminal block of the adjacent Cabinet Module via the
connecting cables. The connecting cables are of two different types:
● 2-core cable for 230 V 1AC,
● 2-core cable for 24 V DC.
The auxiliary voltage supply system is delivered in a fully operational state. The cabling between the terminal block
and the relevant Cabinet Module is installed at the factory. The only work remaining to be carried out on site is to
connect the power to the adjacent Cabinet Module by connecting the cables to the next terminal in the line. Within
transport units these connections are assembled at the factory.

DRIVE-CLiQ wiring

Cabinet Modules are shipped with all DRIVE-CLiQ connections ready-wired within the cabinet. This applies
regardless of the ordered options.
Connections between cabinets cannot be ready-wired on shipped units, as the plant conditions are not precisely
specified in the order and the extremely wide range of connection/topology options would make ready-wiring
impossible. These cable connections must therefore be ordered separately.
Cables inside the Cabinet Module should be routed according to the specifications for signal cables in the EMC
Installation Guideline. The cables must be routed in such a way as to ensure fault-free operation.
Cables are generally routed in the direction of the cabinet cross-beam from where they can be routed through the
cross-beam to the next cabinet.
With this type of cable installation, component replacement will not be hindered by cable routing. It also ensures that
cables are securely mounted.
Only original Siemens DRIVE-CLiQ cables may be used, as only these cables with their special properties ensure the
fault-free operation of the system.
Inter-cabinet DRIVE-CLiQ connecting cables can also be fitted at the factory on request. This option can be ordered,
for example, with order-specific Integration Engineering (order number 6SL3780-0Ax00-0AA0).
