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. Refer to NEC Article 725 Class 1, Class2, and Class 3 Remote-Control, Signaling, and Power Limited Circuits for requirements concerning class 1 circuit conductorsand class 2 power supplies.Table D.5 Control Circuit Terminal Power SupplyInput / Output Terminal Signal Power Supply SpecificationsMulti-function digital inputs S1, S2, S3, S4, S5, S6, S7, SC, SP, SN Use the internal control power supply of the drive or anexternal class 2 power supply.Multi-function analog inputs +V, A1, A2, AC, FM, AMn Drive Short Circuit RatingThe drive is suitable for use on a circuit capable of delivering not more than 100,000 RMS symmetrical Amperes, 600 Vacmaximum (600 V Class) when protected by Bussmann Type FWH or FWP fuses as specified in Factory RecommendedBranch Circuit Protection on page 350.u CSA Standards ComplianceFigure D.4 CSA Markn CSA for Industrial Control EquipmentThe drive is CSA-certified as Industrial Control Equipment Class 3211–06.Specifically, the drive is certified to: CAN/CSA C22.2 No. 14-13 and CAN/CSA C22.2 No.274-13.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.n L1-01: Motor Overload Protection SelectionThe drive has an electronic overload protection function (oL1) based on time, output current, and output frequency that protectsthe motor from overheating. The electronic thermal overload function is UL-recognized, so it does not require an externalthermal relay for single motor operation.This parameter selects the motor overload curve used according to the type of motor applied.D.3 UL and CSA StandardsYASKAWA TOEP YAIZ1U 03B YASKAWA AC Drive – Z1000 User Manual 357D Standards Compliance
