Safety Precautions Refer also to Precautions for ll Relays. Precautions for Correct Use Installation 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 C loads do not contain a permanent magnet. When mounting a P7MF-0(-D) Front-mounting Socket to a DIN Track, attach PFP-M End Plates on both sides of the Socket to prevent it from moving. Gang Mounting Conditions for Gang Mounting Relays Relay Models for DC Loads Rated current of Relay ack-connecting Socket Socket Front-Connecting Socket Models for 5 * C Loads * Gang mounting of the Front-Mounting Sockets is not possible if the contact carry current exceeds.provide space on both the right and left sides of the Sockets. The mounting pitch is given in the following diagram. Test utton Turn OFF the power supply before operating the test button. lways 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 operations minimum. Operating Environment Do not use the Relay in environments with combustible gas. Doing so may result in explosion due to arcing. 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-0P or P7MF-0(-D) Socket. pplied current () 0 5 5 0 0 0 30 0 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).
