• 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

) for power terminals, and twist
the wire ends before attaching the ring terminals.
