Auxiliary Power Generation In The Line Connection Module; Insulation Monitoring; Cable-Marshaling Compartment 200 Mm High - Siemens SINAMICS S120 Operating Instructions Manual

2.6.14

Auxiliary power generation in the Line Connection Module

Using this option, the auxiliary power is generated in the Line Connection Module.
The following auxiliary voltages are available:
● 2 AC 380 up to 2 AC 480 V; 2 AC 500 up to 2 AC 690 V
(possible tap depending on the Line Connection Module 35 A to 80 A)
● AC 230 V (possible tap, approx. 4 to 6 A)
● 24 V DC (possible tap, approx. 20 to 40 A)
Note
You can find a description in the "SINAMICS S120 Cabinet Modules" Manual, Chapter,
"Options / K76, auxiliary power generation in the Line Connection Module".
2.6.15

Insulation monitoring

In non-grounded systems (IT systems), the insulation monitor checks the entire electrically-
connected circuit for insulation faults.
The insulation resistance as well as all insulation faults from the line supply to the motors in
the Cabinet Modules are detected. Two response values can be set (between 1 kΩ and
10 MΩ). If a response value is fallen below, an alarm is output at a terminal. A system fault is
output via the signaling relay system.
Note
You can find a description of the insulation monitoring in the "SINAMICS S120 Cabinet
Modules" Manual, Chapter, "Options / L87, insulation monitoring".
2.6.16

Cable-marshaling compartment 200 mm high

Because it is raised 200 mm, the cable marshaling compartment facilitates higher bending
radii for cables (cable entry from below) and cable routing within the cable marshaling
compartment.
Note
You can find a description of the cable marshaling compartment in the "SINAMICS S120
Cabinet Modules" Manual, Chapter, "Options / M07, cable marshaling compartment, 200 mm
high, RAL 7035".
