Wiring the SIMG After Installed onto the KBMG - See Figures 3 and 4. [. . . ] Removing the KBMG Finger-Safe Cover If a finger-safe cover is not installed on the KBMG, proceed to section IIC (Modifying the KBMG Finger-Safe cover). If a finger-safe cover is installed on the KBMG, remove the two (2) socket head 5-40 X 5/16" screws located at the rear of the KBMG using the supplied 3/32" hex key. Also, remove the two (2) 6-32 X 1-3/4" screws located on either side of terminal block TB1. See figure 4 on page 8.

FIGURE 3 KBMG/SIMG ASSEMBLY DIAGRAM B. Removing Terminal Block TB1 from the KBMG Remove terminal block TB1 from SIMG Finger-Safe Cover the KBMG by rocking it back and forth or using a screwdriver to gently pry it off. The removed terminal block (4 places) TB1 will not be used and may be discarded.
C. Modifying the KBMG Finger6-32 x 1-3/4" Screws Safe Cover (2 places) Once the KBMG finger-safe cover is removed, it has to be modified to accommodate the SIMG. Cut out the finger-safe cover panel Cable at seven (7) places as Assembly shown in figure 6 on page Note: 9. (Note: Some fingerYellow to F+ safe covers may already Brown to Fhave the panel removed. ) To access the field termi5-40 x 5/16" nals (F+ and F- on the Screws KBMG) cut out the field (2 places) tab of the KBMG fingersafe cover at three (3) places as shown in figure 7 on page 9.

Connections to the SIMG Safety Warning!Do not use FWD-STOP-REV contacts as a safety disconnect since they are not fail-safe. Use only the AC line for this purpose.
!
Note: SIMG Enable jumper J1 must be installed, or a connection must be made between EN and COM terminals of SIMG TB1 in order for the KBMG to operate. TABLE 2 TERMINAL BLOCK (TB1) WIRING INFORMATION

B. Signal Following from Armature Voltage Uses motor armature voltage as a signal input. If the signal input voltage applied to the SIMG is derived from a motor armature voltage output, it is necessary to install a 1/4W resistor in series with the signal lead into the SIMG. for a 180V DC motor, install a 330K resistor.
