ARMATURE CONNECTION

IV. MOUNTING.

Mount the KBRG-213D on a flat surface free of moisture, metal chips, or corrosive atmosphere.

See Mechanical Specifications fig. 7, p. 6. A 5K ohm remote speed potentiometer is provided

with each control. Install potentiometer using hardware provided. Be sure to install insulating

disk between potentiometer and inside of front panel.

Enclosure – When mounting the KBRG-213D in an enclosure, it must be large enough to allow

the proper heat dissipation. A 12"12"24" enclosure is suitable at full rating. Smaller

enclosures may be used if full rating is not required.

V. WIRING.

Warning! To avoid erratic operation do not bundle AC Line and motor wires with

potentiometer, voltage following, enable, inhibit or other signal wiring. Use shielded

cables on all signal wiring over 12" (30 cm) – Do not ground shield.

Wire control in accordance with National Electric Code require-ments and other local codes that

apply. A “normal blo” 15 amp fuse or circuit breaker should

be used on each AC line conductor which is not at ground

potential (do not fuse neutral or grounded conductors). (See

section VI, p. 8 for fuse information.) Wire control in accor-

dance with connection diagram (see fig. 6, p. 5). A separate

AC Line switch or contactor must be wired as a disconnect

switch so that contacts open each ungrounded conductor of

the control.

A. AC Line – Connect AC Line to terminals L1 and L2. (Be

sure jumpers J1 and J2 are set to match the AC Line

voltage used.) (See table 4, p. 3.)

B. Motor Armature – Connect motor armature to terminal

A1 and A2. (Be sure jumper J3 is set to match motor

voltage.) (See table 4, p. 3.)

C. Field – [For Shunt Wound motors only. Do not use F1

and F2 terminals for any other motor type.] Connect

motor shunt field to terminals F1 and F2 for 90VDC

motors with 100VDC fields and 180VDC motors with

200VDC fields. For motors with half voltage fields, 90VDC motors with 50VDC fields and

180VDC motors with 100VDC fields, connect field to terminals F1 and L1. See table 6 for

summary of field connections.
