Minarik NRGD-4Q Series, User Manual

NRGD–4Q drives have nine user-adjustable trimpots. Each drive
is factory calibrated to its maximum horsepower rating. Readjust
the calibration trimpot settings to accommodate lower horsepower
motors.
With the exception of the TACH trimpot, all adjustments increase
with CW rotation, and decrease with CCW rotation. The TACH
trimpot increases with CCW rotation, and decreases with CW
rotation. Use a non-metallic screwdriver for calibration. Each
trimpot is identified on the printed circuit board.
Warning
Dangerous voltages exist on the drive when it is powered,
and up to 30 seconds after power is removed and the motor
stops. When possible, disconnect the voltage input from the
drive before adjusting the trimpots. If the trimpots must be
adjusted with power applied, use insulated tools and the
appropriate personal protection equipment. BE ALERT.
High voltages can cause serious or fatal injury.
