1.
To mount the AM4 on a BWC150/225, use the dimensions in Figure 1.2 to locate and drill two 3/16" holes as
shown in Figure 1.2.
2.
To remove the AM4 cover, insert a small flat blade screwdriver into the slot located on the tapered end of the control
and lift the cover off. Attach the AM4 base to the inside of the jacket panel using two #8-32 x 3/4 screws and hex
nuts as shown in Figure 1.3.
3.
Insert the long ribbon cable into the socket labeled X7 on the AM4 module and attach the other end of the ribbon
cable to the socket labeled X7 or X8 on the MCBA. Bundle the excess ribbon cable and secure it with
the clip provided on the inside of the RH jacket panel under the junction box.
4.
Refer to the 0-10VDC control manufacturer's instructions for the size and type of wire to use for the 0-10VDC
connections. In general, it is a good idea to route this wiring away from potential sources of electrical noise, such
as transformers, power lines, and fluorescent lighting. Where such sources cannot be avoided, it may be necessary
to use properly grounded shielded cable. Run the 0-10VDC wiring through one of the 7/8" openings in RH
jacket panel above the junction box and connect the positive (+) wire to terminal X2-1 and the negative (-) wire to
terminal X2-2 (Figure 1.4 Detail).
5.
Connect the alarm wiring to terminals X1-1 and X1-2 in the AM4 module (Figure 1.5) and run this wiring through
one of the openings in the RH jacket panel above the junction box.
6.
Reinstall the cover on the AM4 module.
