3-14 Network Cabling and Base Plate Installation
The base plate contains two integral DIN rail tabs that securely grab a 35mm
DIN rail onto which the base plate is mounted. The base plate may be used on
both 35mm x 7.5mm and 35mm x 15mm DIN rails. To release the Base Plate
from the DIN rail, sequentially insert a flathead screwdriver into the DIN rail
release tabs and gently pull away from the DIN rail (figure 3.13).
Four keyhole slots are provided for affixing the Type 1D DIN Base Plate to a wall
or panel (figure 3.14).
The 1D Base Plate is supplied with a jumper plug that connects the power and
network connections between adjacent base plates. The Jumper Plug is shipped
inserted into the main cavity of the Base Plate, and can be removed by gently
pulling the plug handle in the direction of the mounting arrow. The Jumper Plug
must be removed before a DM-21 module can be inserted into the Base Plate.
