Wiring

3.1 Terminal assignment and power supply

When you configure electromotive locking, you must connect the actuator (manufacturer-

specific locking module for control of the actuator) with correct polarity to ACTp (positive

terminal) or ACTn (negative terminal) for locking. The technology module changes the

polarity of these connections when the direction of actuation is changed.

● Unlocked: ACTp = 12 V; ACTn = 0 V; max. current 10 mA

● Locked: ACTp = 0 V; ACTn = 12 V; max. current 10 mA

The tolerance of the 12 V voltage between ACTp and ACTn is ± 6%.

Note

When the selected electromotive connector locking consumes a current greater than 10 mA,

you must install a suitable locking module (actuator) in between.

Comment: If you use an actuator with reverse logic, you must wire the connectors

accordingly.

In case of electromagnetic connector locking (e.g. by means of a solenoid), the ACTn

connectors work as an open collector. This means you must connect the actuating magnet

involved in the locking process to a suitable power supply (12 V, SELV/PELV) and connect

the negative connector of the actuating magnet to the ACTn of the respective charging

outlet. See Block diagram (Page 29). The maximum permitted current is 1.3 A in this case.

External L+ power supply (only for BaseUnit type B1)

Connect an external 24 V DC power supply of the type SELV/PELV (according to EN61010-

2-201, Class 2) to the L+ and M connectors to supply the SIMATIC ET 200SP TM ECC

2xPWM ST technology module with voltage. The voltage input of the technology module has

an electrical reverse polarity protection.

Note

L+- and M isolation on the SIMATIC ET 200SP TM ECC 2xPWM ST technology module

provided by the BaseUnit type B1.

The L+ and M connectors on the BaseUnit of type B1 are galvanically isolated from the

neighboring BaseUnits to the left and right. The L+ and M busbars run through the BaseUnit

type B1 (without connectors) and expand the busbar with connectors for BaseUnits on the

left and right.
