Connecting the supply voltage for the safe extension modules:
1. Connect the supply voltage to terminal points A1 (24 V DC) and A2 (0 V) of the respective
safe extension module.
Connections A1/A2 supply the clock/signal outputs as well as the inputs and outputs
(MSI-EM200-8I4IO) or the signal outputs (MSI-EM200-4RO).
The logic of the safe extension modules is supplied with voltage via the yellow MSI-TBUS DIN
rail connector.
WARNING: Loss of the safety function
The use of unsuitable voltage supplies and the incorrect connection of the voltage supply
can result in the loss of the safety function.
Only supply the supply voltage at connections A1/A2 and 24/0V on the base device of
•
a MSI 100/200 system via the same voltage supply.
Likewise, supply the supply voltage for all other devices participating in the system via
•
the same voltage supply.
Only use power supply units with safe insulation and SELV/PELV in accordance with
•
EN 50178 / VDE 0160.
Connect the two supply connections (A1/A2 and MSI-TBUS) for an intended function of the
safe extension modules.
