Precautions When Using Solid-State Starters
When using solid-state starters, there are two precautions
servicing personnel need to be aware of.
WARNING
STARTER AND MOTOR TERMI-
NALS REMAIN “HOT” AT HIGH
VOLTAGE EVEN WHEN MOTOR
AND STARTER ARE “OFF.”
Be Certain To Disconnect All
Power To The Unit Before Per-
forming Any Work In The Starter
Panel.
The “In the Phase” starter does not remove voltage
from any of the six motor leads when it is off. Three
of the six motor leads remain directly connected to
line voltage with respect to ground. The remaining
three terminals are pulled up to the line voltage
through the motor impedance of each phase. See
Figure 18 .
