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