5 INSTALLATION, MOUNTING INSTRUCTIONS AND ELECTRICAL CONNECTIONS
WARNING! DO NOT USE THIS DRIVE IN EXPLOSION-PROOF APPLICATIONS. BE SURE
THE DRIVE IS SECURELY MOUNTED.
5.1 Location and Mounting – The KBIC ® controls should be mounted on a flat surface and located in
an area where it will not be exposed to contaminants such as water, metal chips, solvents or
excessive vibration. When mounting in an enclosure, the air space should be large enough to
provide adequate heat dissipation. The maximum allowable ambient temperature at full rating is 45
ºC/113 º F. Consult factory if more information is required.
5.2 Initial Setup and Wiring.
a. Install proper size Plug-in Horsepower Resistor ®
.
(See Table 6, on page 11).
b. The KBIC can be connected to a standard 115V or 230V (±15%) 50/60 Hz AC line based on
model selected [Be sure the AC input voltage corresponds to the control voltage rating and the
motor rating (e.g. 90-130VDC motor on 115VAC and 180VDC motor on 230VAC)].
c. Follow the recommended supply wire sizes as per Table 3, on page 9.
d. Follow the NEC and other electrical codes that apply.
CAUTION: Separate branch protection must be provided on 230V circuits. Do not fuse neutral or
grounded conductors.
e. Connect control in accordance to connection diagram. (See Figure 1, on page 4).
f. When using a step-down transformer (440 VAC to 230 VAC) be sure the VA rating of the
transformer is at least 3 times the VA rating of the motor.
WARNING! READ SAFETY WARNING, ON PAGE 5, BEFORE USING THE DRIVE.
DISCONNECT MAIN POWER BEFORE MAKING CONNECTIONS TO THE DRIVE. TO AVOID
ELECTRIC SHOCK, BE SURE THE DRIVE AND MOTOR ARE PROPERLY GROUNDED.
