Interconnecting Terminal Base Units
Follow the steps below to install another terminal base unit on the DIN rail.
1. Position the terminal base on the 35 x 7.5mm DIN rail (A).
2. Make certain the side connector (B) is fully retracted into the base unit.
3. Slide the terminal base unit over tight against the neighboring terminal
base. Make sure the hook on the terminal base slides under the edge of
the terminal base unit.
4. Press down on the terminal base unit to lock the terminal base on the
DIN rail. If the terminal base does not lock into place, use a screwdriver
or similar device to open the locking tab, press down on the terminal
base until flush with the DIN rail and release the locking tab to lock the
base in place.
5. Gently push the side connector into the side of the neighboring terminal
base to complete the backplane connection.
Panel/Wall Mounting
Installation on a wall or panel consists of:
• laying out the drilling points on the wall or panel
• drilling the pilot holes for the mounting screws
• installing the terminal base units and securing them to the wall or panel
IMPORTANT
Make certain you install the terminal base units in order of
left to right.
