The P7M-06P, P7MF-06, and P7MF-06-D can be used with models for DC loads with an SPST-NO or SPST-NO/SPST-NC contact form or with models for AC loads with an SPST-NO or SPST-NO/SPST-NC contact form. 2. The P7MF-06-D has a built-in diode and can thus be used only with Relays with DC operating coils. Do not use it with a Relay with an AC operating coil. 3. Refer to Gang Mounting in the Safety Precautions section for the conditions required to gang mounti multiple relays side-by-side. 4.

Precautions for Correct Use Operating Environment Installation Do not use the Relay in environments with combustible gas. Doing so may result in explosion due to arcing. * Models for DC loads (i.e., models with "X" in the model number) have permanent magnets built into the insulating block. If a permanent magnet or other magnetic body comes near the Relay, magnetic interference will occur with the built-in permanent magnet and the contact switching capacity will be decreased. * Models for AC loads do not contain a permanent magnet. * When mounting a P7MF-06(-D) Front-mounting Socket to a DIN Track, attach PFP-M End Plates on both sides of the Socket to prevent it from moving. Storage Models for DC Loads (i.e., models with "X" in the model number) are magnetized because they have a built-in magnet to deflect and extinguish the arc. Do not install the Relay near IC cards or other items that may be adversely affected by magnetism. Usage Use the Relay mounted in the P7M-06P or P7MF-06(-D) Socket. Gang Mounting Test Button Conditions for mounting multiple MKS-X relays on the same DIN rail. * Turn OFF the power supply before operating the test button. Always return the test button to the original position after you use it. * Do not use the test button as a switch. * The durability of the test button is 100 operations minimum. Socket Back-Connecting Socket Front-Connecting Socket Models for 10A DC Loads Models for 15A AC Loads * Relay Rated current of Relay The circuit can be checked using either of two modes. Test Button DC specification: Blue AC specification: Red Applied current (A) * Gang mounting of the Front-Mounting Sockets is not possible if the contact carry current exceeds 10A.Provide space on both the right and left sides of the Sockets.

Mounting interval Wiring * The contact terminals on Models for DC Loads (i.e., models with "X" in the model number) have polarity. Wiring with incorrect polarity may result in inability to turn OFF the Relay or loss of functionality. * Be sure to check plarity when wiring DC coil MKS-X relays with built-in operation indicators.
