• Use shielded wire for the PG encoder signal lines.
• Use separate conduit or cable tray dividers to separate option control wiring, main circuit input power wiring, and motor
output power cables.

<1> A separate UL Listed class 2 power supply is necessary when the PG requires more than 200 mA to operate.
PG Encoder Power Supply Voltage
For the PG-X3 option, set the voltage for the PG encoder power supply using jumper CN3 located on the option. Position the
jumper as shown in Table 8.9 to select the voltage level.
NOTICE: The positioning of jumper CN3 selects the PG encoder power supply voltage (5.5 V or 12 V). Select the voltage level for the PG
encoder connected to the option and motor. If the wrong voltage is selected, the PG encoder may not operate properly or may become
damaged as a result.

PG-X3 Wire Gauges and Tightening Torques
Wire gauge and torque specifications are listed in Table 8.10 . For simpler and more reliable wiring, use crimp ferrules on the
wire ends. Refer to the option manuals for the wire size and torque specifications of other options.
