CAUTION
Mechanical stress or shock! Overheating! Terminal Fusite damage!
Mechanical stress and shocks to the Fusite must be avoided as they could
damage the glass and/or ceramic. This might result in hermetic failure or loss
of terminal performance. Precautions are required to prevent striking or
bending of pins.
Ensure correct connection of cables to the compressor terminal Fusite to avoid
local overheating.
Cable glands have an influence on the protection class of the terminal box. Emerson strongly
recommends to use appropriate cable glands according to EN 50262 in order to reach the rated
protection class. Examples of correct electrical installations are shown in Figures 19-21 below.
