3.3 Installation of Housing Barrel
The
flameproof surface
of the housing fits quite closely since the explosion-proof grade is
high. During installation, especially pay attention to protecting the
flameproof surface
; as
shown in the figure, the rear cover and the rear side of the barrel are flameproof surfaces,
which shall not be impacted or scratched during installation.
Figure 11. Careful Installation of Housing Rear Cover
An insulating spacer is provided between the drawer plate and the rear cover plate in the rear
cover assembly, and its insulation performance shall be paid attention to in case
disassembling is required; after assembling, measure its insulating resistance to ensure that it
is not less than 100
MΩ. There is an externally grounded bolt in the center of the rear cover,
which shall be reliably connected to the earth when the equipment is installed.
