[. . . ] Proper installation, which includes wiring, mounting in proper enclosure, fusing or other over current protection, and grounding can reduce the chance of electrical shocks, fires, or explosion in this product or products used with this product, such as electric motors, switches, coils, solenoids, and/or relays. Eye protection must be worn and insulated adjustment tools must be used when working with control under power. This product is constructed of materials (plastics, metals, carbon, silicon, etc. ) which may be a potential hazard. Proper shielding, grounding, and filtering of this product can reduce the emission of radio frequency interference (RFI) which may adversely affect sensitive electronic equipment. [. . . ] For reverse operation, set the desired preset speed Jumper to the "R" position. Speed Range Selection (HI, LO) ­ All HI and LO Jumpers are factory installed for full motor speed range. For more precise adjustment over a narrower speed range (high, medium, or low) set the HI and LO jumpers as shown in Figure 4.

Removing the KBMG FingerSafe Cover ­ If a finger-safe cover is not installed on the KBMG, proceed to Section III B. If a finger-safe cover is installed on the KBMG, remove the two (2) socket head 5-40 X 1/4" screws located at the rear of the KBMG using the supplied 3/32" hex key. Also, remove the two (2) 6-32 X 13/4" screws located on either side of Terminal Block TB1 of the KBMG. See Figure 8. KBMG Finger-Safe Cover KBMG 7 B. Removing Terminal Block TB1 from the KBMG ­ Remove Terminal Block TB1 from the KBMG by rocking it back and forth or using a flat blade screwdriver to gently pry it off. The removed terminal block will not be used and may be discarded. See Figure 9. FIGURE 9 ­ REMOVING TERMINAL BLOCK TB1 FROM THE KBMG Terminal Block TB1 C. Modifying the KBMG Finger-Safe Cover ­ Once the KBMG finger-safe cover is removed, it has to be modified to accommodate the KBMG Multi-Speed Board. Cut out the finger-safe cover panel at seven (7) places as shown in Figure 10, on page 9. Note: Some finger-safe covers may already have the cover removed. KBMG D. Installing the KBMG Finger-Safe Cover ­ Once the KBMG finger-safe cover has been modified, it can be installed onto the KBMG. Initially, use only the two (2) 5-40 X 1/4" socket head screws, using the supplied 3/32" hex key. [. . . ] See Figure 14.
