Xylem IM131R01 AQUAVAR AV II - Manual (Page 9)

8
8. The AQUAVAR controller has electronic safety devices which will stop the motor in the event of
electrical or thermal faults. This does not remove power to the AQUAVAR controller.
9. The system must be properly grounded before being put into operation. Use a common
ground for the entire system.
10. High voltage tests of the AQUAVAR controller may damage the electronic components.
Before carrying out such a test, bridge the incoming and outgoing terminals L1 - L2 - L3 - U - V -
W. Isolate the motor from the AQUAVAR controller drive to avoid incorrect capacitor metering inside
the AQUAVAR controller.
Safety Instructions
FAILURE TO DISCONNECT AND LOCKOUT ELECTRICAL POWER AND WAIT
FIVE MINUTES FOR CAPACITOR DISCHARGE BEFORE SERVICING AQUAVAR
CONTROLLER CAN CAUSE SHOCK, BURNS, OR DEATH.
WARNING!
TOUCHING THESE COMPONENTS SERIOUSLY ENDANGERS LIFE! Voltages of up to
800 volts are possible (higher if there is a fault).
Before removing the AQUAVAR controller drive top cover, the system must be discon-
nected from the main power supply. After switching off the power supply, you must
wait at least 5 minutes before starting work on or inside the
AQUAVAR controller drive
head. This allows the capacitors in the circuit to be discharged by the discharge
resistors.
Note
Care must be taken when connecting external control wires and jumpers to avoid short circuit to neighboring components.
Note
Repair of electrical faults can lead to the automatic restart of the motor and pump.
You must remove all main line power to the
AQUAVAR controller before attempting to
correct a fault.
Note
WARNING
Hazardous voltage
can shock, burn or
cause death.
