Power Cord Specifications

Use copper conductors only.

Power Cord

0.75 to 2.5mm

Diameter

(18 - 12 AWG)

Conductor Type Simple or Stranded Wire

Conductor

Length

*1 If the Conductor's end (individual) wires are not

twisted correctly, the end wires may either short

against each other, or against an electrode.

Power Connector (Plug) Specifications

(2) Loosen three screws in the center of the

Power Connector (plug).

(3) Strip the power cord, twist the conductor's

wire ends, insert them into the pin terminal

and crimp the terminal. Attach the terminal

to the Power Connector.

• Use a flat-blade screwdriver (Size 0.6 x

3.5) to tighten the terminal screws.

The torque required to tighten these

screws is 0.5 to 0.6 N•m [5-7Lb•In.].

• Do not solder the cable connection.

(4) Attach the Power Connector (plug) to the

PL and fix it to the PL main unit with

right/left tightening screws.

Power Supply Cautions

• Input and Output signal lines must be sepa-

rated from the power control cables for

operational circuits.

• To improve the noise resistance, be sure to

twist the ends of the power cord wires

before connecting them to the Power con-

nector (Plug).

• The PL unit's power supply cord should

not be bundled with or kept close to main

circuit lines (high voltage, high current), or

input/output signal lines.

• To reduce noise, make the power cord as

short as possible.

• If the supplied voltage exceeds the PL

unit's range, connect a voltage transformer.

• Between the line and the ground, be sure to

use a low noise power supply. If there is an

excess amount of noise, connect a noise

reducing transformer.
