IPMG Positioning Indicators
In compliance with many safety standards, such as NFPA 70E, the position of
the IPMG device is seen through a standard viewing window. The Lexan
viewing window is on the lower half of the main medium voltage power cell
door. The switch is in the CLOSED or GROUNDED position when the blades
are in a vertical position. If the blades are not readily visible and/or if they are
in a more horizontal position, the IPMG device is in the OPEN position.
There is a secondary position indicator where the operating handle is used.
The graphic below details the location of the indicator that shows you what
position the IPMG device is in.

ATTENTION:
After operating the IPMG device, verify the position
indicator matches the label. Adjust if necessary before operating the
isolation switch handle.
