NOTE:
Make the wires CN4 as short as possible. Do not
install the wires along the 230-400V power line.
Separately install them at a distance of more than
30cm. (Intersecting as applicable.) If the wires are
installed along the power line, put the wires in a metal
tube and connect a wire to an end for grounding. The
maximum wiring length is 70m. In the case that this
function is used, it is recommended that safety devices
such as electric leakage breaker or smoke detector,
etc. be used.
§
Remote Control 1 (Level Signal Input) (1)
This is an ON/OFF function from a remote place by using
level signal (or ON/OFF). The basic wiring and time chart
are shown bellow.

NOTE:
Picking up signal within 10 seconds after power supply
is turned ON is not available due to initializing of
components.
§
Remote Control 2 (Pulse Signal Input) (2)
This is an ON/OFF function from a remote place by using
Pulse Signal. The basic wiring and the Time Chart are
shown below.
Turn off the power source before setting the dipswitch as
