Replacing Relays
To replace output relays, first remove the cover using the following procedure.
Reference Data The following reference data shows actual measured data from sampling in a
production line. There is some variation in relay characteristics, so use this
data for reference only.
(1) Hook your fingers under the handle and bend it upwards.
(2) The side will bend
out in the direction
of the arrow,
releasing the hook.
(3) Using a tool such as a screwdriver, press
down on the relay socket lever and
remove the Relay from the socket.
