<1> Codes refer to a set of three crimp terminals and three insulation caps. Prepare input and output wiring using two sets for each connection.

Note:

Use crimp insulated terminals or insulated shrink tubing for wiring connections. Wires should have a continuous maximum allowable

temperature of 75 °C 600 Vac UL-approved vinyl-sheathed insulation.

n

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 i.29 Control Circuit Terminal Power Supply

Terminal Signal

Power Supply Specifications

Open Collector Outputs

DM+, DM-

Requires class 2 power supply

Digital inputs

S1 to S8, SN, SC, SP, HC, H1, H2

Use the internal LVLC power supply of the drive. Use class

2 for external power supply.

Analog inputs / outputs

+V, -V, A1, A2, A3, AC, AM, FM

Use the internal LVLC power supply of the drive. Use class

2 for external power supply.

n

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: 4Eoooo and 4Woooo), and 500 Vac maximum (400 V

class: 4Aoooo and 4Poooo) with built-in fuses manufactured by Hinode Electric Co., Ltd. and Mersen (or equivalent).

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: 10% to 180% of the drive rated current
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.
