Selecting power supply units

You are advised to use the devices in the following table. These devices meet the applicable
requirements of EN 60204-1.

Note
When using an external 24 V power supply with a continuous current > 20 A, an overcurrent
protection device must be used for the S120 Combi Power Module, the cables and the
busbars. A circuit breaker is recommended as overcurrent protection device.
The tripping characteristic of the circuit breaker depends on
• the loads to be protected and
• the maximum current provided by the power supply unit in the case of a short-circuit.

When an external power supply is used, e.g. SITOP, the ground potential must be
connected to the protective conductor system (DVC A).
