DIN-Rail Mounting the Series 92
1. Place the Series 92 upper mounting clip on the top edge
of the DIN rail. See Figure 2.
2. Press down firmly on the top front edge of the Series 92,
see Figure 2 Mounting for location. The control "snaps"
securely onto the rail. If the control does not snap on,
check to see if the DIN rail is bent. The DIN rail specifica-
tion is DIN EN 50022, 35 mm X 7.5 mm. Minimum
clipping distance is 1.37" (34.8mm), the maximum is
1.39" (35.3mm).
Removing the Series 92 from the DIN-Rail
1. Place your fingers on the release lever located at the
base of the Series 92. See Figure 2 Removing.
2. While gently pressing on the top of the case, above
Terminals 1 - 9 (see Figure 2 inset), pull forward on the
release lever.
Mounting the Series 92
1. Using the control as a location template, mark both
mounting holes.
