KB Electronics KBDA-42 - Manual (Page 20)

6.2 GROUND CONNECTION – Connect the ground wire (earth) to any available green Ground Screw.
The two Ground Screws are located near Terminal Block TB1. Be sure the motor is also properly
grounded. See Figure 10, on page 18, and Figure 11, above.
6.3 MOTOR CONNECTION – Connect the motor to Terminal Block TB1 Terminals “U”, “V”, “W”. See
Figure 10, on page 18, and Figure 11, above. Be sure the motor is properly grounded. Motor cable
length should not exceed 100 ft. (30 m) – special reactors may be required – consult our Sales
Department. Be sure Function No. 0.01 is set to the corresponding Motor Nameplate Current.
Note: If the motor does not rotate in the desired direction, either: 1. Reverse any two motor leads
(with AC line disconnected and motor stopped). or 2. Use the FWD/REV Key. or 3. Use Function
No. 1.02 to reprogram the forward and reverse direction.
6.4 MULTI-FUNCTION OUTPUT RELAY CONNECTION – The Multi-Function Output Relay Contacts
are located at TB2, as shown in Figure 12. The Multi-Function Output Relay is factory pro-
grammed to function as a “Run” relay (Function No. 5.00 set to “0000”). When the drive is put into
the Run Mode, the relay contacts will change state (the Normally Open (N.O.) contact will close
and the Normally Closed (N.C.) contact will open). See Table 5.
