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. Use a class 2power supply for the control circuit terminal when not using the internal control power supply of the drive. Refer to NECArticle 725 Class 1, Class 2, and Class 3 Remote-Control, Signaling, and Power Limited Circuits for requirements concerningclass 1 circuit conductors and class 2 power supplies.Table C.5 Control Circuit Terminal Power SupplyInput / Output Terminal Signal Power Supply SpecificationsMulti-function digital inputs S1, S2, S3, S4, S5, S6, S7, S8, SC, SPUse the internal control power supply of the drive or anexternal class 2 power supply.Multi-function analog inputs +V, -V, A1, A2, A3, ACPulse train input RP, ACPulse train output MP, ACSafe disable inputs H1, H2, HCSafe disable outputs DM+, DM- Requires class 2 power supplyn 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 Installing Fuses on the Input Side on page 238.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.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.C.2 UL and CSA StandardsYASKAWA ELECTRIC TOEP C710616 41B YASKAWA AC Drive - A1000 Quick Start Guide 247C Standards Compliance
