Precautions for Correct Use Installation Test Button • 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. Conditions for Gang Mounting Relays Socket Back-Connecting Socket Front-Connecting Socket Models for 10A DC Loads ❍ ❍ Models for 15A AC Loads ❍ * Rated current of Relay 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. The mounting pitch is given in the following diagram. 20 15 10 5 0 0 10 20 30 40 50 Mounting interval (mm) 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. • Wire models with built-in operation indicators with the correct coil polarity (DC operating coil). 10 Operating Environment Do not use the Relay in environments with combustible gas. Doing so may result in explosion due to arcing. Storage Gang Mounting Relay • 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. 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.
