Slide the relay board into the place according to the insertion guide.
(Note) Engage the patterned section of the board with the metal pad section of the connector and insert the board in parallel. When the insertion angle inclines, remove the board once and try again.
Engage the patterned section of the board with the metal pad section of the connector and insert the board in parallel.
When the metallic parts of the relay board is touched with bear fingers, they oxidizes and the contacting failure occurs. Put on gloves for the work.
②Connecting two options
Connect options with reference to the diagram below.
Triangular mark on the side face
Fit two option’s positioning guides on both units and connect two units not to shift the connecting position of the relay board. Hold a triangular section on the side of the unit and engage the relay boards securely.
(Connection is satisfactory when the click sound can be heard.)
If there is a gap between the units, two boards are misaligned. Carry out the work again from the beginning.
