Low Voltage Wiring for Control Circuit Terminals
Wire low voltage wires with NEC Class 1 circuit conductors. Refer to national state or local codes for wiring. The external
power supply shall be a UL listed Class 2 power supply source or equivalent only.
Table C.6 Control Circuit Terminal Power Supply
Input / Output Terminal Signal Power Supply Specifications
Digital inputs S1 to S8, SC
Use the internal LVLC power supply of the drive. Use class
2 for external power supply.
Analog inputs / outputs +V, A1, A2, A3, AC, AM, FM
Use the internal LVLC power supply of the drive. Use class
2 for external power supply.

Drive Short Circuit Rating
The drive is suitable for use on a circuit capable of delivering not more than 100,000 RMS symmetrical Amperes, 240 Vac
maximum (200 V Class), 480 Vac maximum (400 V Class), and 600 Vac maximum (600 V Class) when protected by Bussmann
Type FWH or FWP fuses as specified in Factory Recommended Branch Circuit Protection on page 236.

CSA Standards Compliance
Figure C.7 CSA Mark
n
CSA for Industrial Control Equipment
The 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 Protection
Set parameter E2-01 (motor rated current) to the appropriate value to enable motor overload protection. The internal motor
overload protection is UL listed and in accordance with the NEC and CEC.
n
E2-01: Motor Rated Current
Setting Range: Model-dependent
Default Setting: Model-dependent
Parameter E2-01 protects the motor when parameter L1-01 is not set to 0. The default for L1-01 is 1, which enables protection
for 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.
