PointScan/200 Series Panel Assembly
PointScan/200 Series I/O snaps onto DIN rail strips fastened to the subpanel. The following figure shows
a sample panel with DIN rail strips and wire duct attached. Recommended DIN rail spacing is 8 inches.
This spacing allows room for wire duct to be installed without obstructing field wiring installation.
The PointScan/200 Series modules are typically installed against one another, but space may be left
between modules to accommodate other DIN rail mounted components such as terminal blocks and fuse
holders. End clamps are recommended to restrict side-to-side movement. The next figures show the
physical dimensions of the PointScan/200 Series components.
PointScan/200 Series modules may be installed in any orientation and order on your panel. The modules
are electrically interconnected using RS485 wiring, beginning with the gateway.
