9.3 Replacing the coding element at the power connector of the system
power and load current supply
Introduction
The coding consists of a 2-part coding element.
Ex factory a part of the coding element is inserted into the back side of the power connector.
The other part is firmly inserted in the system power supply or load current supply module.
This prevents the insertion of a power connector of a system power supply or load current
supply module into a supply module of a different type.
DANGER
Do not manipulate the coding element, or leave it off
• If you undertake changes to the coding element or replace it, then this can lead to
dangerous conditions in your plant.
• In order to prevent damage, you must not change or replace the coding.
• The coding element may not be left off.
Replacement parts scenario
Insertion of the coding element into a new power connector in the case of a replacement
part.
DANGER
Dangerous voltage
When installing the coding element, you must take into account the supply voltage of the
power supply module, 24 VDC, 24/48/60 VDC or 120/230 VAC/DC.
Only install the coding element with switched-off voltage.
You must insert the coding element in such a way that the power connector matches the
power supply module in terms of voltage.
