Wiring The Power And Data Cables - Siemens SIMATIC EMS400S PSB-S Operating Instructions Manual

4.5.2

Wiring the power and data cables

The PSB modules are equipped with terminal blocks for wiring the power and data cables.
The terminal block assignments are specified in the section "Interface description
(Page 62)".
You may wire conductors with a cross-section from 0.3 mm
terminal boxes. The following connectors are suited for conductor cross-section from
0.2 mm
● X11 on PSB-S module
● X12 on the PSB-C module
Electrical accident through contact
The RAIL contact conductors are connected to 48 V AC, while the L1, L2 and L3 contact
conductors are operated on a voltage of 400/500 V AC. Contact with components carrying
these live voltages poses the risk of an electrical accident. Such an accident can result in
physical injury or death.
Always adhere to the necessary safety measures taken for the respective electrical system
components.
Electrical accident through fault
A mechanical fault in the contact conductor system of the system can result in a short-
circuit between the L1, L2 and L3 contact conductors and the RAIL contact conductors.
Contact to components on live 400/500 V AC can result in an electrical accident. Such an
accident can result in physical injury or death.
Always adhere to the necessary safety measures taken for the respective electrical system
components.
Observe the "Safety instructions" section in the "EMS400S Plant controller for Electric
Monorail Systems" system manual.
Requirement
● The terminal box is open.
● The conductor to be terminated is stripped to a length of 6 mm.
