6.3 Fusing
AC Line Fuse – The KBRG-212D does not contain an AC line fuse or
fuse. It is recommended that a 20 Amp fuse or circuit breaker be
each AC line conductor not at ground potential. In addition, refer to Table
recommended Armature Fusing.
CAUTION: Most electrical codes require that each ungrounded conductor contain
fusing. Separate branch circuit fusing may be required. Check local electrical codes.
6.4 Motor Armature – Connect motor armature to terminals M1 and M2. Be sure that
jumper J2 matches the motor being used. (See Figure 3).

6.5 Field (For Shunt Wound Motors Only) – Connect motor armature leads as above.
Connect full voltage shunt field leads (90 volt motors with 100 volt fields and 180 volt
with 200 volt fields) to F+ and F-. Connect half voltage field leads (90 volt motors
with 50 volt fields and 180 volt motors with 100 volt fields) to F+ and L1. See Table
8, Figures 4 and 5, on page 15, for field connection diagrams.
CAUTION! Shunt-Wound motors may be damaged if field remains connected without
motor rotating for an extended period of time.
Note: Do not connect motor armature leads to F+ and F- terminals. Do not use F+ and F-
terminals for PM motors.
