Do not tighten these screws strongly
so that wiring arrangement can be
easily made by rotating or removing
the terminal panel.
Cut the bushing into
hole circumference
length, and place it
over a hole edge.
Caution
When installing on top of the JB-031B, make sure the wiring of the
installed unit cannot directly touch the JB-031B's rear panel edge.
In cases where wiring touches the panel edge, protect the cables
from the panel edge by covering the edge with tape or by inserting
the cables in tubes, provide proper spacing between the units to
prevent the cables from touching the panel edge, or take such
appropriate countermeasures.
