Basler Electric BE1-851 - Manual (Page 264)

installed at the factory, one pin should be visible when viewed from the side of the unit. This
configuration allows the inputs to Operate at the higher end of the control voltage range. Figure
12-1 illustrates the location of the jumper terminal blocks as well as the position of a jumper
placed in the high voltage position.
3. To select operation at the lower end of the control voltage range, install the jumper across the two
pins. Use care when removing and installing each jumper so that no components are damages.
4. When all jumpers are positioned for operation in the desired control voltage range, prepare to
place draw-out assembly back into the case.
5. Align the draw-out assembly with the case guides and slide the assembly into the case.
6. Tighten the screws.

Mounting
Case Cutouts and Dimensions
Because the relay is of solid-state design, it does not have to be mounted vertically. Any convenient
mounting angle may be chosen. BE1-851 Overcurrent Protection Systems are available in three case
styles. These styles are the F1, H1, and S1 cases. Overall dimensions for the S1 case are shown in
Figure 12-2. S1 case cutout dimensions are shown in Figure 12-3. S1 adapter plates are shown in
Figures 12-4 and 12-5. Overall dimensions and cutout dimensions for the H1 case are shown in Figures
12-6 through 12-8. Information on two-relay installations is shown in Figures 12-9 and 12-10. Adapter
bracket 9289924100 allows a single relay to be mounted in a 19-inch rack (see Figure 12-11). A second
adapter bracket (9289929100) performs the same function but includes a cutout for an ABB FT switch
(see Figure 12-12).Overall dimensions for the F1 case are shown in Figure 12-13. F1 case cutout
dimensions are shown in Figure 12-14. All dimensions are given in inches and millimeters.
