Wiring Cautions

3.2.1 Connecting the GP's Power Cord

• To avoid electric shocks, be sure the Power Cord is un-
plugged from the power outlet when connecting the
power terminals to the GP unit.
• GP-377 Series units accept DC 24V power input only. Us-
ing an incorrect power supply will result in damage to
both the power supply and the GP.
• Re-attach the GP Terminal Strip's clear plastic cover after
completing wiring. If the Cover is not installed, it may
cause an electric shock.
When the FG terminal is connected, be sure the wire is grounded. Not
grounding the GP unit will result in excessive noise.
• Wherever possible, use thick wires (max 2mm
exposed wire ends when connecting the Ring Terminals.
• Please use the following size Ring Terminals.
• To prevent the Ring Terminals from causing a short when the terminal block
attachment screws are loosened, be sure to use sleeve-type Ring Terminals.
l l l l l Connect the GP Power Supply Terminals as follows:
1) Be sure that the GP's Power Cord is not plugged in to the power supply.
2) Remove the Terminal Strip's clear plastic cover.
3) Remove the screws from the three (3) middle terminals, position the Ring
Terminals as shown above and re-attach the screws. (Check each wire to make
sure the connections are correct)
4) Re-attach the Terminal Strip's clear plastic cover.
A torque of only 0.5 to 0.6 N•m is required to tighten an attachment screw.
