The MFD-CP4 is protected against polarity reversal. Ensure
the correct polarity of the terminals to ensure that the
MFD-CP4 functions correctly.

When the MFD-CP4 is switched on for the first time, its
power supply circuit behaves like a capacitor. Use a suit-
able device for switching on the power supply and do not
use any reed relay contacts or proximity switches.
With the power supply ensure that the response threshold
for the short-circuit current is higher than the inrush
current of the MFD-..-CP4.
