DANGER!
Connect inputs I1–I8 on AC base devices and I1–I4 on expansion
devices in accordance with all applicable VDE, IEC, UL, and CSA
safety rules using the same phase conductor that delivers the supply
voltage. The device will otherwise not detect the switching level or
may be destroyed by overvoltage.
Inputs I5–I8 on expansion EASY-E4-AC-16RE1(P) can be connected to
a different phase.
Ensure that the L and N conductor are not reversed.
