Wiring
• When connecting a wire to the GP's FG terminal, be sure the wire
is grounded. Not grounding the wire will result in excessive
noise.
• To avoid a short caused by loose ring terminals, be sure to use
ring terminals with an insulating sleeve.
• Wherever possible, use thick wires (max. 2 mm
2
) for power terminals, and twist
the wire ends before attaching the ring terminals.
• Be sure to use the following size ring terminals.

WARNING
• To prevent an electric shock, be sure the GP's Power Cable is un-
plugged from the power outlet prior to connecting the cable's termi-
