3.3.2. Connecting Power
 Refer to “2.13. CN5: Connector for Power Supply” for details.

Use AWG18 of anti-heat vinyl UL cables for the power supply.

Do not place the main power AC line cable and the signal wires in close proximity. Do not tie wrap them,
and do not put them in the same duct or conduit.

Separate the wiring of the primary and the secondary noise filters, and take different routing.

The Driver Unit and the noise filters shall be close to each other.

Be sure to install the surge killer circuit to the coils of magnetic switch, relay and solenoid. Refer to
catalogs of each manufacturer for more details.

An inrush current is generated when the power is turned on because of the capacitive load connected to
the main power supply circuit. For this reason, use the contacts such as a magnetic switch that has a higher
rated current as shown below.
