Notch position 1 is shown. 44325 44228 1. Using a bladed screwdriver, rotate the keyswitch on the mounting base clockwise until the number required for the type of module being installed aligns with the notch in the base. 2. Make certain the DIN rail locking screw is in the horizontal position.
POINT I/O 8 Channel High Density Current Input Modules 11 Install the Removable Terminal Block (RTB) A removable terminal block is supplied with your wiring base assembly. To remove the terminal block, pull up on the RTB handle. This allows the mounting base to be removed and replaced as necessary without removing any of the wiring. To reinsert the removable terminal block, proceed as follows. 1. Insert the end opposite the handle into the base unit.
POINT I/O 8 Channel High Density Current Input Modules Install a 1734-TOPS Base 1. Position the base vertically above the installed units, such as an adapter, power supply, or existing module. 2. Slide the base down, allowing the interlocking side pieces to engage the adjacent installed unit. 3. Press firmly to seat the base on the DIN rail until the base snaps into place. 4. Verify that the DIN-rail locking screw is in a horizontal, locked position before inserting an I/O module.
