l Refer to “2.12. TB: Terminal Block for Power Supply” for more details.
l Provide anti-heat vinyl AWG16 cables for the power supply cable.
l Do not place the main power AC line cable and the signal wires in close proximity. Do not
bundle up them and not put in the same duct.
l Install a noise filter between the power source and the Driver Unit to protect the System from the
external noises.
Table 3-3: Noise filter requirement [Recommended manufacturer: Schaffner]
Power source Type Rated voltage Rated current
Single phase
100VAC, 200VAC
FN2070-40 250 VAC AC10A
l Separate the wiring s of the primary and the secondary noise filters, and take different routing.
l The Driver Unit and the noise filter shall be close to each other.
l Be sure to install the surge killer circuit to the coils of magnetic switch, relay and solenoid.
l An inrush current flows when the power is turned on because the capacitive load is connected to
the main power supply circuit. For this reason, use the contacts, if necessary, such as magnetic
switch that have higher rated current as shown below.
