<1> Maximum MCCB rating is 15 A, or 200% of drive input current rating, whichever value is larger. MCCB voltage rating must be 600 Vac or greater.
<2> Maximum Time delay fuse is 175% or drive input current rating. This covers any Class J, T, or CC fuse.
<3> Maximum Non-time delay fuse is 300% of drive input current rating. This covers any Class J, T, or CC fuse.

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. Refer to NEC Article 725 Class 1, Class
2, and Class 3 Remote-Control, Signaling, and Power Limited Circuits for requirements concerning class 1 circuit conductors
and class 2 power supplies.
Table i.36 Control Circuit Terminal Power Supply
Input / Output Terminal Signal Power Supply Specifications
Multi-function digital inputs S1, S2, S3, S4, S5, S6, S7, SC, SP, SN
Use the internal control power supply of the drive or an
external class 2 power supply.
Multi-function analog inputs +V, A1, A2, AC, FM, AM

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) and 480 Vac maximum (400 V Class), when protected by Bussmann Type FWH or FWP fuses as
specified in Installing Fuses on the Input Side on page 78.

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.
n
L1-01: Motor Overload Protection Selection
The drive has an electronic overload protection function (oL1) based on time, output current, and output frequency that protects
the motor from overheating. The electronic thermal overload function is UL-recognized, so it does not require an external
thermal relay for single motor operation.
This parameter selects the motor overload curve used according to the type of motor applied.
Table i.37 Overload Protection Settings
Setting Description
0 Disabled Disabled the internal motor overload protection of the drive.
1 Standard fan-cooled motor (default)
Selects protection characteristics for a standard self-cooled motor with limited cooling capabilities
when running below the rated speed. The motor overload detection level (oL1) is automatically
reduced when running below the motor rated speed.
