(3) Grounding with frame ground (FG) terminal
If a 3-pole AC power supply outlet is not available and the green wire cannot be
grounded, the protective frame ground (FG) terminal on the rear panel must be
connected directly to ground potential.
WARNING
• Prevention of danger using protective ground terminal
If power is supplied without protective grounding, there is
a risk of accidental electric shock. If a 3-pole power sup-
ply outlet is not available and the green wire cannot be
grounded, the protective frame-ground (FG) terminal on
the rear panel must be connected to ground potential be-
fore power is supplied to the MT8801C.
