3 ELECTRICAL CONNECTIONS
See Figure 2 for the connections to the drive.
WARNING! HIGH VOLTAGE! The Safety Warning,
on page 7, must be read and understood before using
the drive. Disconnect the main power before making
connections to the drive. To avoid electric shock, be
sure to properly ground the drive.
3.1 AC Line Input and Ground: Connect the AC line input
to TB1 Terminals L1 and L2. Connect the chassis to earth
ground. Be sure the AC Line voltage corresponds to the drive
voltage rating, as shown in Table 2, on page 2.
3.2 AC Line Input Fusing: The drive does not contain AC
Line fuses. Most electrical codes require that each
ungrounded conductor contain circuit protection. Do not fuse
neutral or ground connections. It is recommended to install a
fuse (Littelfuse 326, Buss ABC, or equivalent) or a circuit
breaker (Square D QOU or equivalent) in series with each
ungrounded conductor. For the recommended fuse or circuit
breaker rating, see Table 2, on page 2.
3.3 Motor Armature: Connect the motor armature to TB1
Terminals A+ and A-. Be sure the motor voltage corresponds
to the drive output voltage rating, as shown in Table 2, on
page 2.
3.4 Armature Fuse: Models KBWT-16, 26 contain a 10 Amp fuse, Models KBWT-110, 210 contain a 15 Amp
fuse, and Model KBWT-112 contains a 20 Amp fuse. The fuse should be rated 1.5 times the full load rating of
the motor. See Table 2, on page 2.
