Safety Precautions

Be sure to read the Common Precautions for All Relay in the website at the following URL:

http://www.ia.omron.com/.

Refer to Products Related to Common Sockets and DIN Tracks for precautions on the applicable Sockets.

Refer to PYF-

@@-PU/P2RF-@@-PU for precautions on Push-In Plus Terminal Block Sockets.

Warning Indications

• Do not use the test button for any purpose other than testing. Be

sure not to touch the test button accidentally as this will turn the

contacts ON. Before using the test button, confirm that circuits, the

load, and any other connected item will operate safely.

• Check that the test button is released before turning ON relay cir-

cuits.

• If the test button is pulled out too forcefully, it may bypass the mo-

mentary testing position and go straight into the locked position.

• Use an insulated tool when you operate the test button.

About the Built-in Diodes

The diodes that are built into the Relays are designed to absorb

reverse voltage from the Relay’s coil. If a large surge in voltage is

applied to the diode from an external source, the element will be

destroyed.

If there is the possibility of large voltage surges that could be applied

to the elements from an external source, take any necessary surge

absorption measures.

Latching Levers

• Turn OFF the power supply when operating the latching lever.

After you use the latching lever always return it to its original state.

• Do not use the latching lever as a switch.

• The latching lever can be used for 100 operations minimum.

Relay Replacement

To replace the Relay, turn OFF the power supply to the load and

Relay coil sides to prevent unintended operation and possible

electrical shock.

Coil tape color

Pink tape is used for the AC coil type and blue tape is used for the DC

coil type, making it easy to distinguish AC and DC.

Screw terminal socket

• Use the following tightening torque for screws during wiring.

• Use the following wire diameters as a guide for wiring.

(Select the appropriate wire diameter for the current used.)

Using a short-circuit bar

• Use the short-circuit bar that is suitable for the socket you are using

and the location of use.

• Note that the P2DN short-circuit bar for the P2RFZ-E Socket has

both a short-circuit bar for shorting coil terminals and a short-circuit

bar for shorting contact COM terminals.

• The short-circuit bar can be cut to match any number of poles. Cut

with a tool as appropriate for the number of relays and sockets.

When using a cut short-circuit bar, take care to avoid injuring your-

self on the cut surface.

• When cutting with a tool, insert the tool from the plastic part and cut

along the slot in the plastic part between terminals. If you cut a part

other than the slot in the plastic part between terminals, it may not

be possible to attach the insulating cap.

• When using a cut short-circuit bar (P2DN), always use the provid-

ed cap to protect the charger part.

• Use the short-circuit bar to short-circuit two or more coil terminals,

or two or more contact COM terminals.

• Do not use a deformed short-circuit bar. Risk of failure, malfunc-

tioning, or deterioration of characteristics.

• In socket terminals, insert the short-circuit bar in the correct orien-

tation all the way into all terminals, and then secure with screws.

• Install the short -circuit bar before wiring.

Common connection method when using a short bar

• When connecting the P2RF-@@-PU input common, insert the short

bar into only the A1 or A2 side.

CAUTION

Indicates a potentially hazardous

situation which, if not avoided, may result

in minor or moderate injury or in property

damage.
