Terminals accommodate wires up to 1.5 mm 2 (16 AWG). See the terminal torque specifications
on page 17 . Digital inputs are connected to these terminals.
LS+, not L+, should be used for short-circuit protection. Each LS+ features individual
short-circuit and EMC protection that make it important to use LS+ for only its four related
inputs.
