VersaFlo UP, UPS
Fault indication wiring diagram
Standby operation with pump 2 as duty pump and pump
1 as standby pump. (requires 2-wire cable)
VersaFlo UPS 3X460V & 575V
Since the 3x460V and 575V pumps are not equipped with
protection modules or relay modules all motor protection
must be provided external to the pump. In addition wiring
the pumps for alternating or standby operation must be
accomplished using external devices.
The pump must be connected to line voltage thru an exter-
nal contactor. The contactor is to be connected to the
pump’s built-in thermal overload switch at terminals P1
and P2 to protect the pump against overheating on both
speeds.
Note: If the pump is also protected by means of a motor
starter, the starter must be set to the current consumption
of the pump at the chosen speed. The motor starter set-
ting must be changed every time the pump speed is
changed. The current consumption at the various speeds is
stated on the pump nameplate.
Wiring Diagram

contactor and start/stop switch using the internal thermal
overload switch.
Installation
