9 50 C100,000 Mounting When mounting more than two Relays side by side, keep a 3 mm gap horizontally and vertically between Relays to ensure a good heat dissipation. It may cause a malfunction if heat is not dissipated smoothly from the Relay. Terminals The terminals fit FASTON receptacle 250 and are suitable for positive-lock mounting. Use only Faston terminals with the specified leads for connecting Faston receptacles with wire diameters that are within the allowable range for the load current. Do not apply excessive force to the terminals when mounting or dismounting the Faston receptacle. Insert and remove terminals carefully one at a time.

10 Do not insert terminals at an angle, or insert/remove multiple terminals at the same to the following table for recommendations of connectors made by Omron .
