Electrical Connections

Risk of severe injury or death by electrical shock.
• To minimize risk of electrical shock, disconnect power before working on or around the system.
• Capacitors inside the drive can still hold lethal voltage even after power has been disconnected—
ALLOW 5 MINUTES FOR DANGEROUS INTERNAL VOLTAGE TO DISCHARGE BEFORE REMOVING
COVER OR WORKING WITH INTERNAL COMPONENTS.
• Once site power has been provided to the control panel and those feeds are live, there will be ener-
gized electrical lines in the control panel up to the remote disconnect terminals even when the
panel's remote disconnect switch is off. Always de-energize the site power feeding the control panel
when opening the panel; otherwise, an electrical shock hazard will still exist which can cause serious
injury, death and major property damage.
• Refer to the VFD Owner's Manual and the VR Pump Owner's Manual for proper wiring, installation and
electrical instructions, and hazards.
• The base booster pump package comes with pre-wired VFDs and an
electrical control panel.
• Provide power and ground wiring sized for the voltage, phase and
fuse size listed on the UL 508A labeled panel. Terminate the power
wiring on the panel's fused disconnect and land the ground wire on
the sub panels electrical stud.

NOTE: Some packages come without an HMI and, therefore, do not need wiring to the VFD.
