Wiring
Section 3-3
The G3PW may be damaged if a command voltage that is higher than 5 V is
applied. If it is necessary to apply more than 5 V, split the voltage as shown
below by inserting resistance in the line to terminal 1 and applying the voltage
across terminals 1 and 3. The internal impedance between terminals 1 and 3
is 30.1 k
Ω
.
Command Input and Power Supply Wire Sizes
Recommended Crimp Terminals
Always use the following crimp terminals (for M3.5) to wire to the command
input and power supply terminals.

Note
Only models with terminal blocks with small slotted screws have
terminal screws.
• Use copper AWG26 to AWG16 twisted-pair cable when connecting the
wires directly.
• Strip the wire sheathing for the following lengths, according to the connec-
tor type.
• Small slotted terminals: 7 mm
• Screwless clamp terminals: 9 mm
• When using twisted wires, it is recommended that you attach a ferrule
with an insulating cover that conforms to DIN 46228-4 and connect the
ferrule to the terminal.
