Wiring Cautions
3.2.1 Connecting the Power Cord
• To avoid electric shocks, be sure the GP unit's power cord
is unplugged from the power outlet when connecting the
cord's power terminals to the GP.
• The GP-37W3 accepts DC24V power input only. Using
an incorrect power supply will result in damage to both
the power supply and the GP.
• Be sure to re-attach the GP Terminal Strip's clear plastic
cover after completing wiring. If the cover is not installed,
it may lead to 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.
• 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.
• Wherever possible, use thick wires (max. 2mm
the exposed wire ends when connecting the Ring Terminals.
• Please use the following size crimp-on type Ring Terminals.
under 6.0mm
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 and only 0.5 to 0.6 N•m of
force.)
4. Re-attach the Terminal Strip's clear
plastic cover.
