● BaseUnit suitable for all fail-safe SIMATIC ET 200SP High Feature motor starters
● The BaseUnit handles the potential group (P1, P2) of the left-hand neighboring module.
● The BaseUnit opens a new 500 V AC infeed group. The potential group (24 V DC) is
looped through.
● The BaseUnit has one F-DI input terminal for fail-safe control signals of the motor starter.
This signal is not forwarded to neighboring motor starters.
● Connection method using push-in terminals
● The touch protection cover for the infeed bus is included in the scope of delivery.
Maximum configuration of the infeed bus
The number of I/O modules that can be used per potential group depends on the following
factors:
1. Total power requirement of all I/O modules operated on this potential group
2. Total power requirement of all loads connected externally to this potential group
The total overall current calculated according to 1. and 2. must not exceed 7 A.
Properties of the F-DI input
The fail-safe digital input "F-DI" has the following properties:
● Use of interconnection type 1oo1 possible
● Sink input
● Input delay 10 ms
● Status indication of input F-DI at motor starter module (green LED)
