Wiring Cautions

3.2.1 Connecting the Power Cord

• To avoid an electric shock, be sure the power cord is
unplugged from the power outlet when connecting the
power terminals to the GP unit.
• The GP2300-LG41-24V/GP2300-TC41-24V and GP2301-
LG41-24V/GP2301-SC41-24V/GP2301-TC41-24V are
designed to use only DC24V power. Using any other
level of power can damage both the power supply and
the GP unit.
• Since the GP is not equipped with the power switch, be
sure to connect a breaker type power switch to the
GP's power cord.
• Be sure to ground the GP's FG terminal. Failure to do
so can lead to an electrical shock or GP malfunction.
• To prevent the Ring Terminals from causing a short when the termi-
nal block attachment screws are loosened, be sure to use sleeve-
type Ring Terminals.
• When the FG terminal is connected, be sure the wire is grounded.
Not grounding the GP unit will result in excessive noise. Use your
country's applicable standard for grounding.
• The SG and FG terminals are connected internally in the GP unit.
• When connecting the SG line to another device, be sure that the
design of the system/connection does not produce a shorting loop.
• Wherever possible, use thick wires (max 2mm
exposed wire ends when connecting the Ring Terminals.
• Please use the following size crimp-on type Ring Terminals.
