Chapter 2 MOUNTING AND WIRING OF THE INVERTER
2.3.5 Wiring for main circuit terminals and grounding terminals
Inverter output terminals, U, V, W and grounding terminal ( G)
1) Connect the three wires of the three-phase motor to terminals U, V, and W, aligning phases each other.
2) Connect the grounding wire of terminals U, V, and W to the grounding terminal ( G).
3) If the cable from the inverter to the motor is very long, a high-frequency current may be generated by stray
capacitance between the cables and result in an overcurrent trip of the inverter, an increase in leakage
current, or a reduction in current indication precision.
When a motor is driven by a PWM-type inverter, the motor terminals may be subject to surge voltage
generated by inverter element switching. If the motor cable (with 460 V series motors, in particular) is
particularly long, surge voltage will deteriorate motor insulation. To prevent this, use the following guidelines:
Inverters of 7.5 HP or above
Motor Insulation Level 1000 V 1300 V 1600 V
460 VAC Input Voltage 66 ft (20 m) 328 ft (100 m) 1312 ft (400 m)*
230 VAC Input Voltage 1312 ft (400 m)* 1312 ft (400 m)* 1312 ft (400 m)*
Inverters of 5 HP or below
Motor Insulation Level 1000 V 1300 V 1600 V
460 VAC Input Voltage 66 ft (20 m) 165 ft (50 m) 165 ft (50 m)*
230 VAC Input Voltage 328 ft (400 m)* 328 ft (100 m)* 328 ft (100 m)*
* For this case the cable length is determined by secondary effects and not voltage spiking.
When a motor protective thermal O/L relay is inserted between the inverter and the motor, the
thermal O/L relay may malfunction (particularly in the 460 V series), even when the cable
length is 165 ft (50 m) or less. To correct, insert a filter or reduce the carrier frequency. (Use
function code F26(Motor sound).)
Chapter 5 FUNCTION CODES
5.1 Function Code Tables
In the ROM version 0800 or later, the factory default of function code H27 (Thermistor for motor,
Level) is changed from 0.16 to 1.6.

Chapter 11 COMPLIANCE WITH STANDARDS
11.5 Compliance with UL Standards and Canadian Standards (cUL certification)
11.5.1 General
Originally, the UL standards were established by Underwriters Laboratories, Inc. as private criteria
for inspections/investigations pertaining to fire/accident insurance in the USA. Later, these standards
were authorized as the official standards to protect operators, service personnel and the general
populace from fires and other accidents in the USA.
cUL certification means that UL has given certification for products to clear CSA Standards. cUL
certified products are equivalent to those compliant with CSA Standards.
11.5.2 Considerations when using FRENIC-Mini in systems to be certified by UL and cUL
To use the FRENIC-Mini series of inverters as a part of UL Standards or CSA Standards (cUL
certified) certified product, refer to the guidelines given below.

Conformity to UL standards and Canadian standards (cUL certification)
If installed according to the guidelines given below, inverters marked with UL/cULare considered as
compliant with the UL and CSA (cUL certified) standards
Integral solid state short circuit protection does not provide branch circuit protection. Branch
circuit protection must be provided in accordance with the National Electrical Code and any
additional local codes.
1. Solid state motor overload protection (motor protection by electronic thermal overload relay)
is provided in each model.
Adjust function codes F10 to F12 and H89 to set the protection level.
2. Connect the power supply satisfying the characteristics shown in the table below as an input
power supply of the inverter. (Short circuit rating)
3. Use 75 Cu wire only.
4. Use Class 1 wire only for control circuits.
Short circuit rating
When protected by class J fuses, suitable for use on a circuit capable of delivering not more
than B rms symmetrical amperes,Avolts maximum.
