4.2.2 Terminal box
WARNING
Ignition source in a potentially flammable atmosphere! Fire hazard!
Any
work on the energized terminals in the compressor terminal box could create
an ignition. Do not touch the energized terminals with a tool or cable when the
compressor is energized.
Compressors operating with flammable refrigerants shall use only the qualified
terminal box supplied with the compressor.
Mechanical stress or shock! Overheating! Terminal Fusite damage and
leakage!
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. Bent or damaged pins may result in loss of hermeticity
and/or terminal performance.
Ensure correct connection of cables to the compressor terminal Fusite to avoid
local overheating of Fusite pins which might lead to refrigerant leaks.
Cable glands have an influence on the protection class of the terminal box. Emerson strongly
recommends using appropriate cable glands according to EN 50262 in order to reach the rated
protection class. Examples of correct electrical installations are shown in
Figure 16 below.
