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).)
DC reactor terminals, P1 and P (+)
When wiring the inverter to the power supply of 50 kVA or more, be sure to connect an optional
DC reactor (DCR).
Otherwise, fire could occur.

8.3 Terminal Specifications
8.3.2 Connection diagram in operation by external signal inputs
(Note 1) Install a recommended molded case circuit breaker (MCCB) or a residual-current-operated
protective device (RCD)/earth leakage circuit breaker (ELCB) (with overcurrent protection) in the
primary circuit of the inverter to protect wiring. Do not use an MCCB or RCD/ELCB whose
capacity exceeds the recommended rated current.
(Note 2) A magnetic contactor (MC) should, if necessary, be mounted independent of the MCCB or ELCB
to cut off the power fed to the inverter. Refer to page 9-1 for details. MCs or solenoids that will be
installed close to the inverter require surge absorbers to be connected in parallel to their coils.
(Note 3) When connecting a DC reactor (option), remove the jumper bar from terminals [P1] and [P+].
Note that the terminal assignment of single-phase 100 V class series of inverters differs that of
the above diagram. For details about the terminal assignment, see Figure 10.1 "Connection
Diagram of DC reactor (DCR)" in Chapter 10.
(Note 4) The THR function can be used by assigning "9" (External alarm) to any of terminals [X1] to [X3],
[FWD] or [REV] (function code E01 to E03, E98, or E99). For details, refer to Chapter 5.
(Note 5) Frequency can be set by connecting a frequency setting device (external potentiometer) between
terminals [11], [12], and [13] instead of inputting voltage signal (0 to +10 VDC or 0 to +5 VDC)
between terminals [12] and [11].
(Note 6) For the wiring of the control circuit, use shielded or twisted wires. When using shielded wires,
connect the shields to earth. To prevent malfunction due to noise, keep the control circuit wiring
away from the main circuit wiring as far as possible (recommended: 10 cm or longer), and never
set them in the same wire duct. When crossing the control circuit wiring with the main circuit
wiring, set them at right angles.
(Note 7) It is recommended for noise control that 3-phase, 4-wire cable be used for the motor wiring.
Connect grounding wires of the motor to the grounding terminal G on the inverter.

Chapter 10 APPLICATION OF DC REACTORS (DCRs)
Since the "Japanese Guideline for Suppressing Harmonics in Home and General-purpose
Appliances" issued by the Ministry of International Trade and Industry (Currently the Ministry of
Economy, Trade and Industry) was revised in January 2004, the general-purpose inverters have no
longer been subject to the guideline. Individual inverter manufacturers have voluntarily employed
harmonics suppression measures. It is recommended that DC reactors (DCRs) specified in Table
10.1 be connected to the FRENIC-Mini series of inverters.

Chapter 11 COMPLIANCE WITH STANDARDS
11.1 Compliance with UL Standards and Canadian Standards (cUL certification)
11.1.1 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.
11.1.2 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 C 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, A volts maximum.
