• To mount vertically (up or down), add an expansion block

either up or down in a back-to-back configuration. In this

configuration, you must use the optional 15 cm (5.9 in.)

ribbon cable, catalog number 1790-15CMCBL, and

alternately position the block in a right-side up,

upside-down fashion.

3. Mount your block on a panel or DIN rail.

Wiring the Terminal Block

WARNING

If you connect or disconnect wiring while the field-side power is on, an electrical
