Notes on Operation
10.1 Insulation Testing
Before the electrical system is put into operation, insulation testing must be performed.
You can find more detailed information in the following standards, for example:
• DIN VDE 0100-600 VDE 0100-600:2017-06 “Low-voltage electrical installations – Part
6: Verification”
• IEC 60364-6:2016 “Low voltage electrical installations – Part 6: Verification”
10.2 Inrush Current
High inrush currents can occur if multiple products are supplied through the same circuit
on the input side. In this case, it is advisable to switch the WAGO Power Supply Pro 2 on
with a delay. The corresponding switch-on delay can be parameterized in the
8
dialog in the “System” section of the WAGO Interface Configuration soft-
ware.
The maximum number of products that can be operated in parallel on one circuit is given
by the sum of the leakage currents. According to EN 62368-1, this sun must not exceed
the maximum value of 3.5 mA.
10.3 Derating
The maximum load is a function of the surrounding air temperature and the installation al-
titude.

10.3.1 Derating (Temperature-Dependent)
Depending on the surrounding air temperature, it may be necessary to reduce the load.
