The pump is powered directly from the Variable
Frequency Drive (VFD). The VFD will be energized 
via an output from the relay board switched through a 
designated relay.

The VFD must be powered separately from the 
control enclosure. The 230 V drive power supply 
must be 230 V, 50-60 Hz, 1 Ø. The 120V drive power 
supply must be 120 V, 50-60 Hz, 1 Ø. The 480 drive 
power supply must be 480 V, 50-60 Hz, 3 Ø. See 
Page 19, Section 2.7 for additional details. The VFD 
on/off switching is done by an output on the relay 
board. The 0-10 V signal from the ULTRAVAC™ 
controller enclosure wired into VFD input relays 5 and 
2 (

see Page 26, Figure 13 through Page 28, Figure 

14) will dictate the speed of the pump. The VFD 
output supply to the pump is 230 V 3 Ø 0-60 Hz for 
115 V and 230 V models and is 480 V, 3 Ø, 0-60 Hz 
for 480 V models. The frequency of the output supply 
signal to the pump will be varied based on the 0-10 V 
signal from the control enclosure. See 

tion 3.2 for additional installation requirements.
