D.3 UL Standards
◆ UL Standards
The RU mark applies to products in the United States and Canada and it means that UL has performed product testing and
evaluation and determined that their stringent standards for product safety have been met. For a product to receive UL
certification, all components inside that product must also receive UL certification.

◆ UL Standards Compliance
This converter is tested in accordance with UL standard UL508C and complies with UL requirements. To ensure
continued compliance when using this converter in combination with other equipment, meet the following conditions:
■ Conditions of Acceptability
1. The “3PH Input Harmonics Filter Module (3PH Input Reactor)”, “3PH Input Reactor 1”, “3PH Input Reactor For
Harmonics Filter” and “3PH Input Capacitor For Harmonics Filter” shall be installed on the input of D1000 Series
device.
2. The D1000 device and its peripherals shall be installed in a suitable enclosure in the end use.
3. The D1000 Series of Power Regenerative devices shall be connected to a VFD which incorporates Solid State Short
Circuit Protection Circuitry and was found to comply with the High Fault Current Short Circuit Test without additional
testing when:
a) The D1000 series uses solid state short circuit protection circuitry for compliance with the Short Circuit Test,
Section 45 of UL508C, 3rd edition
b) The solid state short circuit protection circuitry is used in accordance with 45.1.3 of UL508C, 3rd edition.
■ Installation Area
Do not install the converter to an area greater than pollution degree 2 (UL standard).
■ Ambient Temperature
IP00/Open Type enclosure: -10 °C to +50°C (14°F to 122°F)
IP20/Open Type enclosure: -10 °C to +40°C (14°F to 104°F)
■ Main Circuit Terminal Wiring
Yaskawa recommends using closed-loop crimp terminals on all converter models. To maintain UL/cUL or CSA approval,
UL Listed or CSA Certified closed-loop crimp terminals are specifically required when wiring the converter main circuit
terminals on models 2A0030 to 2A0130, 4A0030 to 4A0630. Use only the tools recommended by the terminal
manufacturer for crimping. Refer to
Closed-Loop Crimp Terminal Recommendations on page 251 for closed-loop crimp
terminal recommendations. The wire gauges listed in the following tables are Yaskawa recommendations. Refer to local
codes for proper wire gauge selections.
Note: The mark indicates the terminals for protective ground connection as defined in IEC/EN 60417-5019.
Grounding impedance:
200 V: 100
Ω or less
400 V: 10 Ω or less
