Before Powering Up - Siemens Simcenter SCADAS RS User Manual

12. Operating Simcenter SCADAS RS
• Make an electrical contact to a grounded structure.
• Mechanically or by using grounding cable accessory (SCRSA-CAB001).
2. Daisy chained stack (distance ≥ 10 m):
• Repeat same process as for Main stack.
3. Daisy chained stack (distance < 10 m):
• No grounding needed (short daisy chain cable shield connects chassis between stacks).
4. Check proper grounding by measuring continuity between stack chassis and external ground with a
multimeter while system is off, and only daisy chain cables are connected to the stacked units.

Before powering up

• Make sure that the power buffer is charged.
• Make sure that ALL cables are properly connected before switching on the power.
• Make sure ALL units and components are mounted securely before operating the system.

Attention!
• Simcenter SCADAS RS does NOT take ground from any power supply.
• Electrical contact between units' chassis in a stack is provided by the short daisy
chain cables, and NOT by the stack mechanism itself.
