E.g., connect all common terminals to the same polarity. • Screw Terminal Model: Do not bend the coil terminals, otherwise the coil wire may be disconnected. Make sure that the tightening torque applied to each terminal is 0.78 to 1.18 N·m and the insertion force is 49 N for 10 s. • Do not reverse polarity when connecting open DC-switching Relays, including 3- and 4-pole models. When soldering solder terminals, do not let flux or other foreign matter adhere to contacts or do not let the coil terminals become bent. Also, solder as quickly as possible because excessive heat may damage the coil. ■ Installation ■ Storage • Do not install the Relays where iron dust can adhere to the contacts or coil. Such dust can prevent the armature from moving freely and inhibit proper electrical contact. • Relays can generate arcs externally. Either install the Relay in a location where a nearby object will not burn or use a covered Relay. • DC-switching Relays contain a permanent magnet in the insulation base. Do not place a magnet or magnetic object near this base. Doing so will reduce the power of the permanent magnet, thus reducing Relay capacity. • Insert PL Back-mounting Sockets from the back of the panel. • To minimize the influence of heat, separate Relays from each other by at least 20 mm for cooling when mounting multiple Relays together. A model for DC loads incorporates a permanent magnetic for arc suppression. Keep floppy disks away from the Relay, otherwise the data on the floppy disk may be damaged. 20 mm min. Top MM MM Mounting orientation Bottom • Relays should be mounted with the armature facing down. ■ Wiring When connecting a load to the contact terminals of a model for DC loads, consider the polarity of the contact terminals so that the generated arcs on the adjacent poles will not collide. If the common connections of the Relay are all positive or all negative, no arc collision will occur. ■ Diode Built into Relays A diode is built into the Relays to absorb reverse electromotive force from the relay coil. The diode will be destroyed if a large external surge voltage is applied. If there is a possibility of a large external surge voltage being applied, take suitable measures to absorb the surge. ■ Operating Environment Do not use the Relay in places with flammable gas, otherwise an explosion may result due to an arc generated from the Relay ■ Switching an AC Load with a DC-switching Model (“X” Model) DC-switching Relays (“X” models) use a magnet to extinguish arcs. The polarity must be correct when you connect the switching section. However, if you connect an AC load, the positive and negative poles of the power supply alternate. This can cause short-circuits due to the collision of arcs that occur when the Relay turns OFF. Therefore, the switching capacity for an AC load is specified as 20 VA or less to prevent short circuits caused by arc collisions. Take sufficient caution if you switch an AC Load with a DC-switching model (“X” models). Common C ＋ − ■ MMXP The MMXP has a hole in the Relay case to allow gas to escape. Do not use this Relay in locations subject to excessive dust. ■ Contact Loads The contact load should be greater than the power consumption of the coil. If it is less than this power consumption or if the Relay is operated very infrequently, the contact can change chemically thus causing unstable operation. Arc collision ■ Refer to the technical guide on your OMRON website for technical descriptions and FAQs on the product. ALL DIMENSIONS SHOWN ARE IN MILLIMETERS.
