K76, auxiliary voltage generating unit in the Line Connection Module

Availability of option
● Basic Line Connection Modules
● Active Line Connection Modules
Description
Cabinet Modules require an auxiliary energy supply to function properly. This current
demand must be included in the configuration and supplied from an external source. If an
external supply is not possible, the required auxiliary voltages can be generated by an
Auxiliary Power Supply Module.
Alternatively, option K76 can be selected to generate the auxiliary voltages in the Line
Connection Module. This is particularly advisable for smaller device configurations.
The following auxiliary voltages are available:
● 230 V AC (poss. tap approx. 4 ... 10 A)
● 24 V DC (poss. tap approx. 5 ... 20 A)
In the Basic Line Connection Module or Active Line Connection Module the auxiliary
voltages are connected to the auxiliary power supply and therefore supply the complete
group of cabinets.
If the Cabinet Modules are delivered as factory-assembled transport units (option Y11), the
electrical installation work has already been carried out.
If the parts are delivered individually, then the auxiliary power interface must be installed on
site.
Depending on the version, the power loss is approx. 100 W.
