Typical Earth leakage
*
*
Typical Earth leakage values were measured at steady-state conditions.
Note that higher leakage currents may occur:
i) under transient conditions such as power on or pump acceleration or
ii) with certain supply configurations such as Earthed phase or
iii) with abnormal supply configurations such as a missing phase or unbalanced supply voltages
Contact Edwards for more information about configuration requirements for Earth leakage reduction.

consumption of the pump’s internal auxiliary power-supply. This auxiliary power-supply is used to power the
pump’s motor-controller, pump-controller and customer accessories.
