Power Terminal Wiring
Use Correct Wires and Terminations for Power Wiring.
L1, L2,PE, R1 and R2 connections should be 14 AWG / 2.5
mm, 300V,105⁰C minimum.
Smaller gauge wires can be used on the C+ and C-
terminals for convince see Control Logic Power Supply
section below. If ferrules are used with 14 AWG wire a precise crimp is
required. The crimped ferrule must measure less than 2.1 mm on each
side of the ferrule or it will not fit into the terminal opening.
The terminals are lever actuated spring terminals that retain high and
constant contact force on any wire through thermal cycling. To operate,
place a small flat bladed screwdriver in the indentation in the lever. Press
down on the lever at approximately a 45⁰ angle with only enough force to
open the clamp, the clamp will full open with about 8 lbs of force, insert
the wire, and release the force on the lever. Check that the wire is in
position with insulation partly into the lead-in window, but not into the
clamp area.
Do not apply direct vertical force or excess force on the
terminal levers. A force of 8 lbs at a 45⁰ angle is sufficient
to fully open the wire clamp, applying a force in excess of
12lbs can damage the terminal.
