A pre-fab. module can be grounded using ground lugs or ground cables.
– Ground lug method: Use a ground lug made of hot-dip zinc-coated flat
steel sheet with a cross-sectional area of 40 mm x 4 mm, connect one
end of the ground lug to the pre-buried ground grid, and connect the
other end to the pre-fab. module ground point. When a ground grid is
pre-buried, the ground lug must be long enough to connect to a ground
point on the pre-fab. module.
– Ground cable method: Use a 95 mm
one end of the cable to the pre-buried ground grid, and connect the
other end to the pre-fab. module ground point. When a ground cable is
used, the ground cable must be routed through a plastic-coated metal
hose.
NO TE
● The screw reserved at a ground point is an M12 screw.
● A pre-fab. module can be grounded in the TN-S or TN-C-S mode.
The water refill ports for humidifiers must supply water continuously when
the FusionModule1000 is operating.
