11.1 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"
11.2 Disable/Enable Overvoltage Protection
The product is protected against overvoltage (for more information, see section
voltage Protection
The letters shown in parentheses refer to positions in the "View" figure in section View.
11.2.1 Disable/Enable Output-Side Overvoltage Protection
Disable Overvoltage Protection
•
Remove the screw (d) on the side of the product.
ð The overvoltage protection is disabled.
Enable Overvoltage Protection
•
Screw in the screw (d) on the side of the product.
ð The overvoltage protection is enabled.
11.3 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 Dialog: Set-
tings dialog in the "System" section of the WAGO Interface Configuration software.
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.
11.4 Derating
The maximum load is a function of the surrounding air temperature and the installation al-
titude.
