n Low Voltage Wiring for Control Circuit TerminalsWire low voltage wires with NEC Class 1 circuit conductors. Refer to national state or local codes for wiring. The externalpower supply shall be a UL listed Class 2 power supply source or equivalent only.Table C.6 Control Circuit Terminal Power SupplyInput / Output Terminal Signal Power Supply SpecificationsDigital inputs S1 to S8, SC Use the internal LVLC power supply of the drive. Use class2 for external power supply.Analog inputs / outputs +V, A1, A2, A3, AC, AM, FM Use the internal LVLC power supply of the drive. Use class2 for external power supply.n Drive Short Circuit RatingThe drive is suitable for use on a circuit capable of delivering not more than 100,000 RMS symmetrical Amperes, 240 Vacmaximum (200 V Class), 480 Vac maximum (400 V Class), and 600 Vac maximum (600 V Class) when protected by BussmannType FWH or FWP fuses as specified in Factory Recommended Branch Circuit Protection on page 236.u CSA Standards ComplianceFigure C.7 CSA Markn CSA for Industrial Control EquipmentThe drive is CSA-certified as Industrial Control Equipment Class 3211.Specifically, the drive is certified to: CAN/CSA C22.2 No. 04-04 and CAN/CSA C22.2 No.14-05.u Drive Motor Overload ProtectionSet parameter E2-01 (motor rated current) to the appropriate value to enable motor overload protection. The internal motoroverload protection is UL listed and in accordance with the NEC and CEC.n E2-01: Motor Rated CurrentSetting Range: Model-dependentDefault Setting: Model-dependentParameter E2-01 protects the motor when parameter L1-01 is not set to 0. The default for L1-01 is 1, which enables protectionfor standard induction motors.If Auto-Tuning has been performed successfully, the motor data entered to T1-04 is automatically written to parameter E2-01.If Auto-Tuning has not been performed, manually enter the correct motor rated current to parameter E2-01.C.2 UL and CSA Standards250 YASKAWA ELECTRIC TOEP YAIP1U 01B YASKAWA AC Drive - P1000 Quick Start Guide
