YASKAWA TOMPC71061753A YASKAWA AC Drive GA500 Installation and Operation Instruction 21
*2 For circuit protection, the main circuit is separated from the surface case that can touch
the main circuit.
*3 The control circuit is a Safety Extra-Low Voltage circuit. Separate this circuit from other
circuits with reinforced insulation. Make sure that the Safety Extra-Low Voltage circuit is
connected as specified.
*4 Reinforced insulation separates the output terminals from other circuits. Users can also
connect circuits that are not Safety Extra-Low Voltage circuits if the drive output is 250
Vac 1 A maximum or 30 Vdc 1 A maximum.
*5 Set L8-05 = 1 [Output Phase Loss Protect Select = Enabled] or set the wiring sequence to
prevent input phase loss.
■ Wire Selection
Select the correct wires for main circuit wiring.
Refer to Main Circuit Wire Gauges and Tightening Torques (for CE Standards) on page 283 for
wire gauges and tightening torques as specified by European standards.
Refer to Main Circuit Wire Gauges and Tightening Torques (for UL Standards) on page 296 for
wire gauges and tightening torques as specified by UL standards.
