Safety Precautions

Maximum Carry Current

• Do not allow the total current for all shorted contact form to exceed the maximum carry current of the Short Bar.

• Do not exceed the maximum carry current of the relay contacts for individual contact form.

• If you use more than one Socket, use End Plates (PFP-M).

Safety Precautions

Refer to the Common Relay Precautions.

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.

Handling

For models with a built-in operation indicator, models with a built-in diode, or

high-sensitivity models, check the coil polarity when wiring and wire all

connections correctly (DC operation).

Installation

• There is no specifically required installation orientation, but make sure that

the Relays are installed so that the contacts are not subjected to vibration or

shock in their movement direction.

• Use two M3 screws to attach Flange-mounted models (MY@F) and tighten the

screws securely (tightening torque: 0.98 N•m).

Using MY-series Relays with Microloads with

Infrequent Operation

If any standard MY-series Relays (e.g., MY4) are used infrequently to switch

microloads, the contacts may become unstable and eventually result in poor

contact. In this case, we recommend using the MY4Z-CBG Series, which has

high contact reliability for microloads (Refer to page 15.)

About the Built-in Diode and CR Elements

The diode or CR element that are built into the Relay are designed to absorb

the reverse voltage from the Relay coil. If a large surge in voltage is applied to

the diode or CR element 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 min.

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.
