9. 2

Compliance with UL/CSA Standards

This inverter complies with the UL Standard and CSA Standard. An inverter that has obtained certifications
of these standards has a nameplate with a UL/CSA mark attached.
9. 2. 1

Cautions for installation

Since this inverter has obtained the certification of the UL Standard on the assumption that it will be
installed in the cabinet, be sure to install it in the cabinet.
Consider ventilation and cooling in the cabinet to keep the ambient temperature (temperature inside the
cabinet) within the specification temperature range. For details, refer to [12. 1].
• With models with applicable motor output of 15 kW or less, the ambient temperature is 50°C or less,
however, if the top cover is removed, the ambient temperature becomes 60℃. Models with applicable
motor output of 18.5 kW or more can be used at an ambient temperature of up to 60°C (without the
top cover).
9. 2. 2 Cautions for wiring
Pay attention to the types and sizes of wires to be used for wiring, types of crimp-style terminals,
tightening torque of screws, etc.
(1)

Power terminal

For wiring to the input terminals ([R/L1], [S/L2], [T/L3]) and output terminals ([U/T1], [V/T2],
[W/T3]) of the inverter and other power terminals, attach rod crimp-style terminals to UL
conformed wires (copper wires with the maximum allowable temperature for conductor of
75°C or more).
• Use crimping pliers recommended by terminal manufacturer to attach rod crimp-style
terminals. For recommended crimp-style terminals, refer to [2. 3. 1].
• Attach them to the terminal block with specified tightening torque. For recommended torque
values, refer to [2. 3. 3].
• For recommended wire sizes, refer to [9. 2. 3].
(2)

Terminal FL, R1, R2

For wiring to the terminal FL ([FLA], [FLB], [FLC]), terminal R1 ([R1], [RC]) and terminal R2
([R2], [RC]) use UL conform wires and rod crimp-style terminal V1.25-3.
• For recommended wire sizes, refer to [9. 2. 3].
• The UL conformed rated output current is different from the inverter unit rated current. For
details, refer to [9. 2. 3].
(3) Other control terminals
For wiring to other control terminals, use Class 1 wires.
• For the recommended torque, refer to the product label
