7.1 LED bulb changes
Warning:
The IP rating of the Hmi-5 unit
depends on correct construction of the button
and LED indicator, opening the button to change
the LED can adversely affect the rating. Please
contact your local Eaton representative for
guidance on this matter.
The LED indicators fitted to the Sonix Hmi-5 are long
life units designed not to be replaced within the typical
lifespan of the unit. If it becomes necessary to change
the indicator during service lifetime care must be taken
to properly re-assemble the button unit to ensure IP
ratings.
Warning:
Inserting the new LED indicator will
most likely result in a button activation, ensure
local procedures have been followed before
commencing work.
