Note on connecting the 2 A output module
Introduction
This section contains information on connecting the 2 A output module (2 amperes) with
SIMATIC TOP connect.
Connecting the supply voltage
Note
Before starting work, make sure you have read the wiring rules in
Wiring rules (Page 21).
The potential supply must be at the front connector module, and a supplementary ground
connection to the terminal module is required for this purpose. To create this ground
connection, follow these steps.
1. Connect the supply voltage to each of the two potential clamps on the front connector
module using separate cables.
2. In addition to the connecting cable, connect one cable for M1 or M2 to each terminal
module.
3. Connect M1 / M2 with a separate cable to the front connector module and terminal
module.
The potential of M1 and M2 can be bridged.
