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.
