motortronics VMX-B Soft Start Packages User Manual

1 REV-02 100418
Manual Addendum for VMX-B Configured Soft Start Packages
For use with wiring diagram # 93-3880 Rev B (CB/FS), or 93-3881 Rev B (MLO), and VMX2 user manual.
Introduction: The VMX-B is a configured enclosed soft start, available as a Combination (with C/B or
Fused disconnect) package, or as an MLO (Main Lug Only) package, intended for use in Industrial,
Commercial, Agricultural, or Infrastructure applications.
Line Voltage:
By default units are set-up for 460VAC line power, but can be adjusted to operate on 230VAC or
208VAC at the reduced HP rating. To adjust the operating voltage simply move wire #1L2B from the
480V (H4) terminal to the 230V (H3) or 208V (H2) terminal.
Power Connections:
Line Power input is connected directly to the bottom terminals of the Circuit Breaker, or line terminals
on MLO (Main Lug Only) units, and the motor is connected to the lugs at the bottom of the VMX2 soft
start.
Remote Start / Stop Control connections:
The VMX-B is set up for 2 or 3 wire remote control using dry contacts rated at 120VAC (0.1Amp).
Remote Two Wire Control:
Connect a dry (voltage free) maintained contact closure between terminals 1 and 3 of the customer
terminal strip as shown here.

Remote Three Wire Control:
For standard 3-wire control, connect dry (voltage free) contacts for the Stop / Start buttons as shown
below of the customer terminal strip. Connect the normally closed “STOP” pushbutton across terminals
1 & 2, and the normally open “START” pushbutton across terminals 2 & 3 of the customer terminal
strip. Note: the unit can be operated in the “Local” position without any external control.
