Acceptable Size and Duration of Power Line Voltage Fluctuations
The Motor Control Module is designed to withstand
voltage fluctuations from the incoming power supply. If
the incoming power supply goes outside of the tolera
-
ble range, an over-voltage condition is flagged and the
system shuts down in an alarm state. Excessive or
repeated over-voltage may permanently damage hard
-
ware. The chart below shows the permissible magni
-
tude and duration of temporary over-voltage events.
Consult a qualified electrician if there are any concerns
about the available power supply.
