3-3 Wiring Methods
Use wire clamps provided to secure the wires and prevent external force from being conveyed by the wire to
the wire connections.
* External force could cause deformation or damage to the terminal blocks.
Use a small screwdriver to connect diameter 0.2 to 2.5 mm
2
(AWG24 to 12) cable for
terminal block (TB21) on the unit. Tightening torque is 0.5 to 0.6 Nm. Up to two wires can
be connected to one terminal block.

to “1”, “2” or “3”, “4” of signal wire
terminal block (TB21).
• TB21-“1” and “3” as well as “2”
and “4” of TB21 are connected
inside the circuit board.
Connect the power supply
wires and grounding wire
to “L”, “N” and “grounding”
of terminal block (TB1).
Connect M-NET signal wire to “A”
and “B” of terminal block (TB2).
• Connect the M-NET
transmission wire to
transmission terminal block
(TB7) of the centralized control.
Attach the appended binding band to the power wire and transmission wire, and fasten it, positioning the
area at inner side than the wire clamp.
Make sure that the ground wire is longer than the other wires.
