The dc controllers are protected against polarity reversal. To ensure
that the unit works correctly, ensure that the polarity of each terminal
is correct.
Wiring Protection
Both AC and DC versions require wiring protection (F1) rated for at
least 1 A (slow).
When the unit is powered on for the first time, the power supply
circuit draws a larger surge current than usual. Use an appropriate
device for switching on the incoming power and do not use any reed
relay contacts or proximity switches.
