Wiring

• To avoid an electric shock, prior to con-

necting the PL unit's power cord terminals

to the power terminal block, confirm that

the PL unit's power supply is completely

turned OFF, via a breaker, or similar unit.

• Any other power level can damage

both the PL and the power supply.

• Since DC type has no power ON/OFF

switch, be sure to attach a breaker-

type switch to its power cord.

• When the FG terminal is connected, be

sure the wire is grounded.

Wiring the AC type power supply cable

• When the FG terminal is connected, be

sure the wire is grounded. Not

grounding the PL unit will result in

excessive noise. Use your country's

applicable standard for grounding.

• Accompanying power supply connector is

a CA7-ACCNL-01 of Pro-face or FKC2,5/

3-STF-5,08 of Phoenix Contact.

Connecting the Power Cord

(1) Confirm that the power is not supplied to

the PL unit.

(2) Push the Opening button by a small and flat

screw driver to open the desired pin hole.

(3) Insert each pin terminal into its each

hole. Release the Opening button to

clamp the pin place.

AC power supply cable

(4) After inserting all three pins, insert the

Power Plug into the Power Connector at

PL. Fix the plug with two minus screws.

• Confirm that all wires are connected

correctly.

• The torque required to tighten these

screws is 0.5 to 0.6 N•m [5-7Lb•In].

• To prevent the possibility of a terminal

short, use a pin terminal that has an

insulating sleeve.

Wiring the DC type power supply cable

• When the FG terminal is connected, be

sure the wire is grounded. Not ground-

ing the PL unit will result in excessive

noise. Use your country's applicable

standard for grounding.
