IP PG power supply
• Output voltage: 12.0 V ± 5%
• Max output current: 200 mA
<1>
IG PG power supply common
AO A pulse monitor signal • Outputs the monitor signal for the A, B, and Z
pulses from the PG speed control card
• For open collector outputs from the option
• Max voltage: 24 V
• Max current: 30 mA
BO B pulse monitor signal
ZO Z pulse monitor signal
IG Monitor signal common
<1> A separate UL Listed class 2 power supply is necessary when the PG requires more than 200 mA to operate.
PG-B3 Wire Gauges and Tightening Torques
Wire gauge and torque specifications are listed in Table 8.4 . 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.
