sp 257 use method 1. both the sp relay 2c and 4c can be mounted to the mounting slats. 2. use the mounting slats either by attach- ing them directly to the chassis, or by mounting with a din rail. (a) when attaching directly to chassis use two m3 screws. for the mounting pitch, refer to the speci- ?cation diagram. (b) when mounting on a din rail use a 35mm 1.378inch wide din rail (din46277). the mounting method should be as indi- cated in the diagram at right. method for mounting on din rail (1) first ?t the arc shaped claw of the mounting slat into the din rail. (2) press on the side as shown in the dia- gram below. (3) fit in the claw part on the opposite side. precautions for use when mounting to a din rail, use a com- mercially available fastening bracket if there is a need to stop sliding of the mounting slat in the rail direction. press relay in fit into mounting grooves. press mounting slat din rail fig. 3 fig. 2 fig. 1 fit in to remove the relay, press down the mounting slats so the claws move to the outside. for cautions for use, see relay technical information (page 48 to 76). 9/1/2000 all rights reserved, ? copyright matsushita electric works, ltd. go to online catalog
