Item Description
1 Wiring the finger-safe terminal block
2 Lower retaining screws
3 Upper retaining screws
TIP The terminal screws are non-captive. You can use a ring lug [maximum
6.35 mm (0.25 in.) o.d. with a 3.53 mm (0.139 in.) minimum i.d. (M3.5)]
with the module.
TIP If you need to remove the finger-safe cover, insert a screwdriver into one
of the square wiring holes and gently pry the cover off. If you wire the
terminal block with the finger-safe cover removed, you will not be able to
put it back on the terminal block because the wires will be in the way.
