WARNING
Uncontrolled and unpredictable operational behaviour!
Failure of certain components in electronic control systems may result in uncontrolled and
unpredictable operational behaviour.
All types of failure and the associated protection systems must be taken into account at
system level.
Comply with all automation system manufacturer instructions.
5.1. Power supply
The device is powered by an external 24 V DC power supply.
Before plugging in the device, ensure that the external power supply meets the required
specifications (type K to 61131-2).

A at +24 V DC (peak current 1.2 A)
B-Primis ET-Prime 10: Total max. 0.6 A at +24 V DC (peak current 1.2 A)
B-Primis ET-Prime 15: Total max. 0.7 A at +24 V DC (peak current 1.2 A)
Internal power supply
A power supply for the system electronics for an input voltage of 24 V DC (
–15% / +20%) is in-
tegrated into the device. The power supply has integrated protection against reverse polarity
and surge current protection (1.2 A).
Installation
All connections and cables must be laid so as to prevent inductive and capacitive interfer-
ence causing any damage to the device.
Ensure that the infeed lines provide adequate current and voltage carrying capacity.
